- MESSAGE:
After a bit of back and forth and with the Help of Dino, Lino and Ricky with the enabling tip, here it is, the eagerly awaited Foam shading Tutorial.
I think this technique can be translated into a lot of different renderers as well as most of them let you alter volumes with textures.
If the reaction on the net to my teases is any indicator this will be my most watched video in the future. Let´s actually see.
I hope you get good results. Feel free to tag me with whatever you get out of this exercise 🙌

History will remember the name Silverwing as it does Einstein. Epic tutorial, thank you for sharing.
You are too kind. That would be kind'a cool 😄
Buuuut as I point out in the video, the idea existed before. I just translated it to Octane 😇
Thank you for your great comment. Made my Day 🙏
Absolutely amazing, many thanks for teaching us how to do it. You deserve a spot in the C4D hall of fame👏👏👏
Hey hey and thank you very much for your comment.
Fantastic to hear you like it and your compliment 🙌
That would be nice if something as a C4D hall of fame even exists 🤔
It's been 3 years since I watched the Silver Wing tutorial, and I thought I learned a lot, but something new always pops up. It's amazing.
Thank you. Yeah, doing my best to bring you new and exciting stuff. As it´s always the case with creativity and development. Not every tutorial is as innovative and "brilliant" as this one. But every once in a while i get there 😄 😇
I hope next tutorial will be "Silverwing Quickish-Tip: Redshift Foam Shader (C4D Redshift)" with latest redshift version
Unfortunately not, but the way it works is very similar to Octane.
You need the newest version of redshift with the Standard Volume in order to make it work. Then take the C4D Volume builder to make your object into a volume. From there on it´s basically the same. I have uploaded a RS scene to my patreon. With a bit back and forth this is definitely doable also on your own though!
fantastic ....SO much learning watching this through
Hey hey and thank you for your great comment. I really appreciate that you find it useful 🙌
Watching and listening to you explain and navigate the Octane UI is poetry in visual motion. Awesome tutorial again, thanks!
Ohhh, thank you so much. Makes me happy you say that.
I was having really bad headaches while recording. So recording was very slow and I needed to record a lot of takes for every single step. Recording went on for 10h 😇
But reading your comment, I think the inconveniences paid off 🙏🙌🫧
OMG Absolutely amazing, many thanks for teaching sir LOVE U
Thaaaank youuuu. Super glad you liked it. This is one of my most successful Tuts I have done so far 😇
Never thought that one could easily switch the meshes to volumes in th object tag! That could also be extremely useful for rendering fluid bodies with non uniform density, like swamp water, tanks filled with mysterious substances and so much more!
Thank you!
Thank you for your comment.
I like the way you think. Yes, those are some really interesting ideas. I like those!
You could possibly also color your volume through a noise or gradient 🙌

Thank you so much. Fantastic to hear that 😊 🙌✨
Amazing! Thank you for working on this and sharing it!
Thank you very much for your comment.
Feedback such as this make my work worth it 🙌
What an bonkers and amazing tutorial Raphael. The little explanations you do inbetween are so valuable. Thank you so much for your deep dive.
Thank you very much for your comment. I actually was a bit afraid I was explaining to little. Great that you find it a good balance 🙏✨
Excited! Always wondered how to do this! Thanks mate!
Thank you very much Grischa.
It´s just one technique. There might be a lot of others out there. Though this works quite nicely 🙌
Awsome tutorial! Thank you very much!
Great to hear you like it. Thank you very much!
Thanks for the amazing tutorial and freebie scenes, Your channel always helps me in solving problems on Octane C4D, thanks.
Thank you very much for your comment.
Fantastic to hear you like my videos 🙏
YOU!!....you are amazing! What a great technique!. Thanks a million!
Thank you very much. I think the technique is a known one and has been used before in Blender. Though it´s good to have it working in Octane 🙌
Awesome! Great tutorial as usual! Thanks Raphael! 🧼
Thank you. Super glad to hear, you like it 🙌
Awesome ! Thanks for that !
You are very welcome 😊 🙌 ✨
I’m doing something with foam as soon as I have some free time! Very interesting technique. Thanks for sharing 🫧
Thank you very much for your comment Lucas! Great to hear you find it useful. Yeah I was a bit skeptical if the technique would even work. But it brought better results then I initially hoped for. So I knew I had something special on my hands for this week 😄
Thank you so much for the ✨🫧✨
This is absolutely amazing. Thank you for your clear explanation and amazing tutorial!
Thank you very much for your comment and your nice words. Fantastic to hear you enjoyed it 🙌
This is so cool! Such a smart way to achieve this look. Thank you for sharing yet another valuable tutorial with the community Raphael 🙌
And thank you for your great comment. Fantastic to hear that you liked it 🙌
really brilliant
Ohhh, thank you so much. Glad you liked it 🙌
unexpected, but such a pleasant solution! Raph, you are great!
Thank you very much. Yeah it´s not the first thing you would think of doing. I guess this makes it a but unique 😊
I did not explain the single steps to closely. e.g. what a Voronoi noise is doing. So I hope the audience can pick that up and understand it as is 😇
Amazing tutorial and really intuitive to follow!
Hey hey, super nice seeing you here Paddi. Great you liked it and you did actually follow 🙌
I see you are getting into 3D artistry ✨
Cheers and an amazing start into this week to you!
seriosly awesome tutorial! Such a great idea on how to make this effect! Incredibly realistic and customizable. Thanks so much for sharing :)!
Thank you. Fantastic to hear you find it useful and versatile 🙌
You are very welcome!
Love when I watch your vids I pick up so many tips. Like I could never really think of a reason to use the compare node, but now I know it’s actually the answer to the issue I’ve had with the add node all along! 👌
Hey hey and thank you very much for your comment. Fantastic to hear that you found some bits that you could learn from! It´s always a joy to hear that the videos are well received 🙌✨
YUUUUUUUUUUUUFFF. Great job bro as always. Simply the highest level of skill.
Thank you very much for the praise.
I am barely translating an existing concept to Octane 😇
Though I greatly appreciate the huge response this video has caused 🙏 🙌
Dude! You are awesome! thanks a million!
And thank you for your great comment. Fantastic to hear that you liked it 🙌
Love it!
Thank you very much. Glad to hear you enjoyed it 🙏🙌
I'm digging your new transitions
Thank you. It´s more or less an experiment ha ha. Glad you hear you like them!
Yeah I think they still miss a bit of a sound effect. Maybe I can get Lucas to make a jingle of some sorts 🤔
you are the gift for the communtiy
Thank you very much for your comment and your kind words.
Every once in a while I find out stuff like this. In the mean time I do lower profile tuts. I hope you still like those 😇
really amazing

Wow so nice. Thank you very much.
You are very welcome 🙏 🙌
Amazing!
Thank you very much 🙌
🫧 Mind blown!! Love these Quicktips as usual. Was experimenting with making Nebulas in Cycles/Blender. Couldn't work out how to translate to Octane. . . . . I do now though. Thank you 🤗
Thank you very much ✨🫧✨
I love your approach. Not only seeing the tutorial itself but also it´s implication and potential on other stuff 🙌
That´s the spirit 🫧
dude you are amazing!
Thank you so much 😊🙌
Amazing work
Thank you very much 🙌 Greatly appreciated!
🫧🫧🫧 I will for sure build out a scene with this new knowledge! Thank you for always providing actually useful and industry building tuts for the community! I'm also patiently awaiting that BEAUTIFUL Opal shader tut!!! Maybe a 2024 premier?? 🤗🤗🤗
Hey Jerome,
thank you very much for your comment and thank you very much for your kind words. Yeah every once in a while I have topics just like this. In the mean time I make more low key tuts that are hopefully helpful as well.
I am still on the development with the opal shader. More off then on right now to be honest as I hit some serious walls. I am not sure if I will ever make it work to the standards I have in mind. Would be so cool though having an opal shader that really behaves and looks like the real thing. Maybe, like with the foam shader just now, I have a breakthrough. Fingers crossed for that!
Cheers and thank you for your support ✨🫧✨
I really appreciate it!
super cool bro thanks!
Great to hear you like it. You are very welcome 🙌✨
That's a brilliantly made tut Raphael. Thank you!!❤
You are very welcome. Glad you like it ✨
@@SilverwingVFX I've posted my version of your tut-outcome on the Octane Group (and also on our Stack - 3dsmax group). Since this is a mind blowing tutorial.
@@OfirGardy Oh, thank you so much for spreading the word. I really appreciate it 🙏🙌✨
Excellent tutorial as always, Raph! Thanks so much. I'll go try this out in Blender Octane tomorrow and get it to work there.
Thank you very much. Appreciate that you like it!
I have made a Blender Octane version too. Heads up. The noises in the volume and the Shader don´t align there.
So you have to turn the volume Shader +90° on the X axis for some reason.
Or, if you are Patreon member, you can download the Blender Octane scene from there... ✨
@@SilverwingVFXAt first I converted the mesh to a volume from the object menu, but couldn't get the textures to match at all. Finally downloaded your scene file and saw that you had done the mesh conversion through geometry nodes, which worked. I had actually thought of the possibility of doing the entire setup in geometry nodes. Between watching your tutorial and looking at the Blender Octane setup, I finally got the desired result. Thanks once again!
Thanks for sharing! Now to try and do it in Redshift.
Thank you very much for your comment. Let me know if you get anywhere. I tried to make it work in RS to. But only managed to go the route with the volume builder that is voxel based and therefore very resource intensive. If you find a way to use Shaders in RS volumes directly (not translated via voxels), let me know!
Perfect! Some months ago I tried to make a foam for a shampoo bottle and I was failed. So it means I will go back to this project again) Thanks a lot!!
Thank you very much!
Good luck with your project. Hopefully you can get there with this technique ✨
Gonna have a go at recreating this technique in Redshift! Nice one :)
Yes please, be my guest. I am all about spreading the knowledge 🙌
life saver!!!
Thanks so much. Super glad hearing that 🙌✨
Hello bro, thank you so much for the tutorial.
Hey there and thank you very much for your comment. You are very welcome. Glad you like it 🙌
😮😮 thanks for best tuts
Hey hey. You are very welcome and thank you for your comment 🙌
很棒的教程！谢谢！
谢谢你的评论。 我很高兴你喜欢这个视频！
This is the genuine solution!
Maybe there are other good ways to do foam. You never know 🤔
But it´s a good one at least ✨
Thanks 🙏
Also thank you 🙌✨
A few months ago I spent many days building a very similar solution for a client project. It worked but ended up being hackier than this solution. Wish I had this back then. Thanks!
Thank you very much. Yeah I know those situations. Actually I was in the same situation before where I just built foam from displacement maps. I had this in mind back then but was not able to get there because the last component, a volume shader that allows density through textures, was missing. Luckily we are here now and whenever I have a request for foam again, I know a good way now.
Well it has its limitations too... but it looks convincing as a still at least🙌
@@SilverwingVFX Yeah, definitely more convincing than anything you could do with displacement. I went through trying displacement, making complex geo through Houdini and finally ended up with something similar to this in the end after seeing someone made something similar in Blender with Cycles.
You are the Best mate...
Thaaank youuu. Glad to hear that ❤️
Very cool effect Raphael. I had an almost exact same setup back when I used Octane but it was dog slow because back then you couldn't just pipe a C4D Noise into Displacement without passing it through the Baking Texture node. So I had to do everything inside the Volume Builder 💀 while using the same noise for a geometry displacement (Displacer deformer). Because surprise surprise, if you use the same noise and seed inside C4D (like a field or something, using the CPU) and in Octane (on the GPU), you get different results. But your quality is insane, just so damn realistic.
Hey neoqueto,
thank you very much for your entertaining message. Yeah. I thought for a longer time how to make it work. And the biggest hurdle was that I could not use VDBs or a voxel based approach because it would be to resource intensive. All those small details in a volume are almost impossible to do on a voxel resolution level.
I also tried to make the same shader in Redshift and did not manage to get there. Because I did not find a way to control the shader with a texture and would have to go through the exact workflow you described above!
I did not even get to the point where the noise of the surface is defined differently then the one in the volume 😬
Great to hear you like the approach I took 🙌
❤beauty!!!
Thank you ❤️
Your renders turn out much better when you're using C4D
Thank you very much for your comment!
I would argue against it. At least technically Octane is doing exactly the same in Blender then in C4D, so there should not be any difference in quality.
Maybe it´s the fact that I have much more assets ready for C4D then for Blender, as I have been using C4D for a lot longer time now 🤔
Cheers and thank you for your comment. I respect your vie of course. It´s always good to have ones own viewpoint challenged.
@@SilverwingVFX Yea, I don't know but I always tend to like your C4D work more. Looks more realistic (in my eyes).
You're doing great. I'm very impressed by your physics knowledge and creativity.
@@flopp4812 Thank you very much for your great response.
I guess I have to work harder to make all my work stand out then 😇
Cheers and a great rest of the week and a good easter time to you!
@@SilverwingVFX Happy easter to you too, looking forward to the next video 👍
I thought it was vdb, turned out to be texturing, bravo!
Thank you very much. Yeah when I first started thinking about it I was sure that It could not be VDBs because it would have been insane ad a huge burden on the scene to put all those details voxels. I am therefore so glad that octane allows you that shader based workflow 🙌
this is amaizing stuf
Thank you so much 😊✨
YES!
Yaaaas 😄
Best!)))
✨❤️✨
certified banger
Yaaaay. Nice 💥
This is really cool, thanks for sharing Raphael!
In real life, wouldn't you also see the specular material refracting inner walls of the bubbles? I wonder if there is a way to create voronoi cell geo from the same noise?
Thank you for your comment. Yes you are absolutely right.
Maybe I should have been going a bit more explaining the physics of it...
Anyway. In reality you would have the reflection of all of those small bubbles but you would not have a volume. So basically what we did is accumulate all the small reflections that would happen in real world and distributed their energy to be a scattering (volume) instead.
Of course there is a difference in real world between scattering and reflection. But the smaller the bubbles are the more those two converge into the same behavior.
So for a more realistic shader it would be nice to have the inside of the bubbles also reflecting. Though this is not possible with our shaders as of now since a reflection needs a polygon wall and can not occur from a volume density change.
There might be some tricks you could use to sort of get there, but there are vastly complicated and, as far as I can think of, all have drawbacks:
I am thinking of creating a parallax occlusion on the surface material as well as some normal direction from the underlying noise to map the reflections of the surface to a depth that is seemingly inside the material with the orientation of the "bubbles" inside.
Though you would have to use stochastics to get different reflection layers on top of each other and since all of it is really only simulated on top you won´t get the natural obscuring of energy through the volume between the internal bubbles.
This is all well beyond my paygrade and also the reason I am struggling with the opal shader material so much as this is playing with ideas along the same lines.
Well, thank you for visiting my ted talk and thank you for reading ha ha ha.
Cheers!
@@SilverwingVFXThanks Raphael, always appreciate your ted talks!! Yes it certainly does seem tricky to get that fully in shader, I was imagining maybe tackling it with something similar to the flakes shader in RS (which I think is similar to what you mention with the parallax occlusion / noise / stochastics), but you're right that the volume won't interact properly.
I'll let you know if I ever tackle the full geo approach in Houdini someday haha. Best of luck with your Opal shader!
Amazing! But now how do we up the level and make this amazing looking foam slide down the side of the bottle, for example? Let this be a consideration for your next tutorial :)
Thank you very much for your comment!
Yeah, that´s the big thing! In other engines such as Arnold or Karma there are so called rest positions that can anchor the noise to a meshes deformation. But this does not exist in Octane yet. I have thought about it a little bit and think this will be rather hard to implement with the available tools.
P.s. foam sliding down the bottle linearly will be OK. It´s just not possible, when the mesh deforms 😇
What a great sharing. Very interesting way to create procedural foam bubbles. Thank you so much.
I am trying to follow your idea to recreate in Redshift. However, I have got a problem to match the bubble cut out and displacement. The shading happens after meshing (displacement) so they can't match. Basically, the texture used for displacement is not going to be the same as the vertices have moved. Just wonder why Octane doesn't have the same issue. Thanks in advance.
Hey hey and thank you very much for your comment.
I think it will work in RS as well. It might be that the noise is not matching up between the volume and the geo.
I remember I had to switch the RS object shader to input source "World" in order to match up with the volume. Not sure if this helps!
I guess there is always a slight mismatch between shading and actual volumetric noise because of the displacement / shading order. But it should still work half way decently and look rather good.
I have a working RS version on my Patreon if you are interested.
It will work in RS 3.6.00 and newer. This is because it has the new RS Standard Volume. Therefore it became possible to control shader density via textures. And therefore finally also create the foam techniques in RS. Though the volume noise can't be moved with the original Object, therefore no animations possible :-(
Silverwing goes full tilt godmode and I am bubbling up the Anthropocene with foamy blobs today :D ... octanly speaking that is :)))) ... the puns aren't entirely my doing, obviously :))))))))))
P.S. I'd love to see a follow up for this showing the treatment for sponges and industrial foam - this is just amazing - so very grateful for the breakdown!!!
Thank you so much 😄
Great to see you here and thank you very much for your ongoing most generous support!
The derivatives like Sponges / Industrial Foam are rather easy. Its just different bubble sizes / shapes.
Also with sponges I think you can skip the surface part altogether and just use the volume.
What would be amazing is to somehow find a hack to be able to bend and deform the volume so you can use it inside deforming geometry. I was not able to think of a solid way to do this yet.
That I would say would be worth a follow up vid.
Anyway it´s hard to follow such a well received tutorial with anything. And I am not that brilliant to have such good ideas every week unfortunately 😇 This was more like a "Once in a lifetime" thing ha ha.
@@SilverwingVFX indeed incredibly inspiring tut + great basis for experimentation! Definitely a major highlight as far as tuts go in general ✨ if my tinkering yields anything in the way of evolution I’ll most certainly will share it 🫧
We need this in blender! Great tutorial :)
I was shown a tutorial after I postet mine that goes a really similar way in Cycles:
Here´s the video I am talking about.

If you want a Blender Octane version. I have a scene for Blender Octane uploaded on my Patreon 😇
@@SilverwingVFX I followed all steps inside Blender Octane and just can't get the noise to match between the foam object and the surface object. Even though I use the exact same node and projection settings 🤔🤔🤔 I bet i am missing something
@@VaggelisRoubos Thank you very much for your comment. I faced the same problem as you did and It took much more time then I am willing to admit to come up with a working solution. However the working fix is very simple:
For some reason the texture space and the volume space do not align. So what you have to do is to rotate the texture space +90° on the X axis.
@@SilverwingVFX maaaaan you 're amazing 🙏 subscribed to your patreon
Woah! this is nothing like i had in mind, Amazing and very eye opening, imagine how more powerful it'll be if we could gave something like pin material, i forecast a flood foamy bear renders for the coming weeks haha, what a trick, in some of my work in product viz, i needed to make a foam shader for a shoe sole and the way i went about it is the usual texture hacks with sss, however i had to change to redshift because with all the displacements in the scene i was constantly at least 4GB out of memory, i was working with a single 2080, fun times (sarcasm)
i was messing with projections on the side, i found out all the primitive ones work but also we can't really pin them to the surface of the geo so the best way to go is the XYZ to UVW, also triplaner works* + sticks to the surface and survives the bend deformer test, however, if you're not careful, your foam turns into swiss cheese or a cowboy hat
i wonder if there's a way to use geo as a cage to deform it with the surface, something like mesh deformer or FFD, all that aside, i think another solution is if in the future it becomes possible to use the standard volume into the medium input in material nodes, that way we can use the pin material tag to freeze it and use deformers on top
thank for unlocking a new part of octane, didn't know that the object tag is this powerful as a shading tool, wish you a great week ahead full of clean 🫧🧼renders
Hey hey. I was waiting for your comment. Thank you again for all your time and effort you pour into those!
About deformation:
I guess we would need a rest state / pin / initial state for that to work.
Right now the noise inside the volume does not even know the objects origin if we don´t explicitly tell it (Through linking the Null). So it´s unfortunately limited to non deforming geo.
Depending on the shoes sole I would probably go with an UV map and then with texture displacement. But it really depends how "foamy" the sole looks and how much of the inside you´d see.
P.s. does the Pin Material work?
I was under the impression that Octane does not have a way to pin materials other then UV maps. Would be really cool if I was wrong here. That would open a lot of other possibilities.
So for what it´s worth this should work for non deforming geometry, though I think there also might be problems with motion blur on fast moving e.g. sponges flying through the air, since the volume is only a translated texture. And I don´t think texture translations are supported by octanes motion blur.
I stated in a comment before that I really prefer cycles approach here having volumes and objects more connected so you get all the things you get in a texture on the volume too, and you do not have problems moving the object and the volume density noise to move with it. But well, you can´t have it all. There is always a thing that does not work and needs a workaround.
I am glad to have gotten so far as this is a very good way to make foam on static- or only slightly deforming geometry. It can get only better from here 🙌
A clean start into this week to you too ✨🫧✨ 😄
haha! of course i enjoy thinking and sharing my experience linked to the topics of your videos 🙌
unfortunately, i can confirm the pin material tag is not working for octane projections, however it works if you'd use the c4d projections on octane materials, even if the object has no UVs
for the shoe inner sole it had voronoi like texture, I'll share with you images once i dig through my old files 🙏
yes i remember that comment and it makes me wonder about the algorithmic limitations that causes these compromises and why isn't there a truly complete render engine (besides real life 😂) in existence, but as you said, it only gets better from here 🙌
Cheers 🫧🌟
@@SilverwingVFX
👍👍👍
🙏🙌✨
Thank you for this great tutorial! Do you think it will work on a deformed object (alembic) without the material sliding?
Thank you for your comment.
The Shader is anchored to the axis of the object.
You would need something like a "reference position" "initial position" like in Arnold.
To my knowledge Octane doesn´t have a feature like this, So the noise will always slide through deforming geometry.
With alembic it also really depends how it was cached in the host app. If the geometry is non deforming and the axis is moving, then it would work. But if the axis is at the scene origin and the points of the geometry are animated, then it would start sliding.
Hope this helps to get a bit of an insight in the matter.
Cheers and a great start into this week to you!
Thank you for the answer, I will try something 🙏🏽
Please advise me, I have the same software version as you do.
This is actually a Swiss Cheese shader in disguise.
It really is. It´s a lot of shaders in disguise. You can do cheese, probably some other food as the inside of bread, sponges, industrial foams, clouds. Basically everything volumetric with bubbles of air inside 🙌
Amazing...🎉 What if I change the shape of the object?
It should just update as intended.
If you have seen my posts on Twitter or Instagram I can also use other objects to hold the foam 🙌
Is it necessary to use c4d2024？no matter what mesh i use， only get a cube foam
Thank you for your feedback.
It should not be necessary to use C4D 2024. This should work with all C4D versions that Octane supports.
I had a comment earlier from someone who had the same problem. I could not recreate it unfortunately.
The only thing I can think of is eventually you have your voxels set to low and therefore your only see one cube.
If you find a solution, I would appreciate if you let us know what it was!
Cheers and thank you very much!
I duplicated my object, but my noise in the glossy material is not in the same pattern as the voxel =/
But great tutorial!
Thank you for your comment.
Make sure you have no transforms in your noise other then scale. Also your object axis need to be on the world origin for the noises to align!
Further, if your density is rather weak it can seem that your noise is not aligning because you can look inside the volume quite a bit so what´s going on inside the volume and on the surface can look disjointed.
I hope you will get there!
@@SilverwingVFX thanks, I'll try again
waw
Thank you 🙌
How do people hide the expiration date of the octane rendering?
Interesting question 🙌
The only solution I have found as of now is to dock your window. So you do not have the window title showing up.
And then you can klick on the hamburger menu and disable "show title".
Let me know if you find another way!
Where can I buy this foam shader?
Thank you very much for your comment.
You can re-built it here with the tutorial. It's not that hard actually.
But you can also subscribe to my Patreon (lowest tear gives you access to everything) Including this foam shader as well as a lot of other shaders, models and scenes.

Why does my oc object label particle rendering not follow the object but a rectangle?
Hey there and thank you very much for your comment.
I think you are speaking of the step where you voxelize your object to make it a volume?
Maybe you have your Tag on the base object instead of the SDS Object.
Or you might have to large voxels and need to make them smaller.
Hopefully one of this will work.
@@SilverwingVFX I followed your tutorial tips for placing labels on the SDS, and in the OC render window it shows a rectangle instead of the actual object shape. The parameter settings for the label and object are the same as yours. Thank you very much for your reply!
My octane tag doesn't have Particle to render; Any work around?
I think it might have something to do with the Octane version that you are using.
It came in around Octane 2022. If you are using a version before that, you do not have the possibility to use "Mesh To Volume"...
Thanks for the quick reply. Yes that is the correct answer, old version; i did found half of a work around using voxels with the volume builder tag but.. still stuck tho. You have a great day!@@SilverwingVFX
You keep blessing us with your amazingness! I used to do this with an animated 10k foam texture, but the file size was enormous (dozens of gb) and it was too overkill for my machine. I'll definitely try your method, this looks fun! Thank you so much! 🫧
Thank you very much Sleezy!
Yeah I know that there are even animated textures for foam out there that also work quite well in certain scenarios. But not in others.
At least my technique is looking decent for the stuff I show it. Definitely has its disadvantages too.... so in the end it´s good to know a couple of methods and just use the one that applies best. And thank you so much for the ✨🫧✨ Yay 🙌
Can you show that in redshift?
Thank you for your comment.
I tried that in Redshift. But I could not make it work yet. Possibly because of my limited knowledge there.
The only possibility I found there was to use the C4D volume builder and use a texture field with a noise in there. But that makes everything dependent on voxels and not textures alone to control densities. And therefore this approach will be very resource intensive.
I will let you know if I find a better way.
Could i use blender?
There is a video on how to do this in Blender Cycles.

If you want this for Blender Octane you can use Geometry Nodes to convert your object to a volume. I think there is a preset in the Modifier Stack.
The only problem I encountered with Blender Octane is that the volume noises initially do not match up with the displacement. However the working fix is very simple: For some reason the texture space and the volume space do not align. So what you have to do is to rotate the texture space +90° on the X axis.

Yaaaaas 🧼✨🫧✨🧼
Me as redshift user... 🥲🥲🥲 Nice tut, but Coffee foam is better, I am going to grab a coffee... haha. Nice tut!
I think this can be also applied to RS. Haven´t tried it though.
P.s. coffee foam for the win ☕🫧
Thank you, great tutorial again. It was totally different from my approach. I used a Replicator to create the bubbles inside and on the surface of the foam mesh, and then Nested Dielectrics to “cut” the foam out where the bubbles are.
🗯< that is technically a bubble. I can't never find the correct emojis. I suspect YT might restrict my emojis :D
Thank you very much Kimmo,
yeah it also took me a bit to realize that the approach was not to put in a lot of geo but to just use shaders in a volume. Of course it´s not completely perfect. Usually you would also have reflections from the inside bubbles that is missing. But it came out a lot more convincing than I thought in the beginning!
About the Emoji. Thank you so much. Love the creative use of it because of restrictions. Looks like a busting bubble ha ha.
Thank you so much for your ongoing support! ✨🫧✨
This is great, I love it! Exactly the stuff I'd love to see in Cycles too, to compare the workflows. Thanks, great work!
Thank you very much. Fantastic to hear you liked it!
I think the technique originated from Cycles. This is one of the thing I like better in Cycles over Octane, it´s good integration of volumes. It´s a bit more easy to do that effect in cycles actually as the volume of objects is not voxel based but also lets you use textures in it´s density.
I wish I had more time to do all the tuts for C4D Octane, Blender Octane and Blender Cycles. But there is a limit to how many tuts I can record in a week... 😄😇
@@SilverwingVFX I'll try to replicate today and let you know how it went :)
@@the_mitacek Thank you 🙏 Looking forward to your results✨
