Hey man, just recently graduated from VFS as a 3d Modeler and wanted to jump into Houdini next. Problem is, I would hear horror stories about it...and after watching a few intermediate/advanced tutorials, I could see why. But then I landed on your series, and I just wanna hug you if I could. This is a top level tutorial series, not just from the content but from the motion graphics to the tonality you're teaching your students. Cheers man, you're a Godsend!
@@fraon7222 Yup! that's right haha! it was a good experience albeit a little expensive. I head great things from Langara, two of my classmates are there now! if you see Kevin and Dan, give them my regards! Good luck man, you're up for a great journey!
Just wanted to throw my support into the comments: these are really great tutorials and I'm really loving the flow. Perfect delivery and just the right amount of details. Thanks!
I really appreciate this tutorial series for Houdini so far. There's a lot of useful information in every video, the step by step walkthrough is clear and easy to follow, and there's not a lot of boring downtime in-between steps. I just wanted to say thank you for taking the time to put these together for us :)
thank you so much for your nice tutorials . im a french beginner on Houdini and i must admit french tutorials are very rare and not so good . you are a good teacher ! please keep on doing this , we need you !
If you have the sphere problem in the render view, go to the "render" tab in the emitter node, go to the "geometry" tab and put "no point rendering" in "Render As Points"
@@poyodiazmusic Disable rendering of DYNAMIC_SPRINKLES. Basically, what happens is that you are already connecting sprinkles to render at SPRINKLES node. On top of that you are rendering DYNAMIC_SPRINKLES which is just bunch of points. For some reason, points are rendered as massive spheres hence it blocks you from seeing the actual sprinkles. DYNAMIC_SPRINKLES in this setting should not be rendered because we are already rendering DYNAMIC_SPRINKLES inside SPRINKLES. Dynamic Sprinkles is just a node that defines how particles should fall, think of it as a function that is only meant to be applied inside other objects and never directly rendered on scene.
@@Navhkrin I solved with the comment from @Fabio Gomes "On the dynamic_sprinkles geometry check the display/render flag on the transform node! Tell me if it worked!" but thanks for the explanation.
Love these tutorials! Been using Maya for a long time but loving Houdini so far. Maybe it's a bit specific but I would love if you went a bit deeper into the workflow of procedural shading/texturing (like controlling the roughness or bump with a combination of noises for example) as well as organized layout of a scene with more objects going over instancing/placement tools etc. Anyhow keep up the good work! :)
Oh man, thank you so much! As a blender user i can now say - Houdini isn't scary thanky to you. I really would love to buy an in depth course from you!
Thanks Ben, I appreciate the kind words! We're dropping a revised and extended version of "Houdini Isn't Scary" called "Houdini is Hip". If you're interested, it'll be released over the coming weeks
Thank you for this. Your videos are the best beginners tutorial for Houdini! I am really starting to see how can can use all the learnings so far in creating my own 3D art. Definitely going to continue learning and will support when I can you deserve it.
Do you think you could do an intermediate tutorial on pyro dynamics? Or destruction FX (I mean fracturing and RBD dynamics and stuff like that)? This tutorial series is really helping me learn Houdini, thanks.
Thank you for these amazing tutos. I love it and it makes it so simple. Now, a quick question, where did you get all the HDRI you are using for this tuto ? Is it on HDRI Haven ?
These tutorials are amazing!!!! But In this one, I found a problem. When I click render, the sprinkles turn into spheres, not tubes. Is there a fix for this? What have I done wrong? Thanks!
Was there a video somewhere for the dynamic sprinkles? I opened the file and found it scary lol. Thank you for making these tutorials they are amazing!
Hey, I really like your tutorials and they help me learning houdini. I can always follow through, but something is not right with my project in Houdini. I created sprinkles but they won't show up in the render. Instead it shows red and white spheres.
If you are seeing the white and red spheres in the render you need to turn off the display flag on the Dynamic_sprinkles geo node. By keeping it on you are running both simulations and the sprinkles are stuck inside the spheres from the base sim we use to drive the motion of the sprinkles. Cheers!
If you are using Houdini 18 or above: DYNAMIC_SPRINKLES GEO- in render tab: Render Visibility instead of * , select invisible (unrenderable...this should work.
If you are following along this tutorial and when coming down to rendering, IF you are using V-RAY for the renderer make sure to give the sprinkles a VrayUserColor into a VraypointParticle in order for V-ray to be able to render particle color, and also make sure you are on CPU rendering since V-ray hasn't got the GPU working with particle colors yet. Also make sure that your "tube" is a polygon and not a primitive because V-ray can for some reason NOT render primitives. I came across this while following the tutorial and tried troubleshooting it myself. So, keep that in mind 🙂
Hello sir thank you so much for the great stuff you've been doing we are all support you and appreciate the effort. I'm just having a little problem, when I start to render the dounut, everything is fine but the icing disappears can you please explain to me why is that happening?
In case somebody else is facing the same issue - if you always see the sphere particles instead of tubes, go to your object network > select the dynamic sprinkles node > Render tab > Geometry tab > Render As Points (Mantra) > select "No Point Rendering" ... (I am using Houdini 20.0.751)
Hi Thank you for your great tutorial. I really appreciate it. I have one question. I've followed your tutorial and it worked out great. But next day I restart my houdini donut, everything works fine except my render view. My sprinkles are looking fine in my Scene view but they look way bigger in my Render view. Why does it happen?
Hey Sabil, you certainly can, it's just a different approach. Because Houdini is procedural and node based, each part of the modelling process is stored as a node. This gives you more control but also makes it a bit more complex. Basically, Houdini is incredible at everything except sculpting. The current packages we use are Houdini (General), ZBrush (Sculpting), Nuke (Compositing), and Substance Painter (Texturing). That allows us to do everything we need.
Following step by step but by some way in rendering my icing does not appear. if i open your file - everything is ok but if I work on mine (which I made following the guide thoroughly) , the icing part just dissapear from the render. Could someone give me an advise where to look at? Cant spot the difference in overall structure. Thanks!
Hello! I follow your tutorial (houdini) with the donut and I have reached the rendering phase, but at the candies iuse tube shape ,I only see some white spheres and some red ones that are glued on the donut! please help me
Большое вам человеческое спасибо! I'm very grateful to you! I haven't got any money right now, so I can't support you but when I will, I will become a patreon :)
You're amazing! it's really hard to find quality houdini tutorials over the internet. Can you tell me the frequency of videos? You plan post one vide per week?
Hey Lui! Thank you for the great comment, I'm glad you're enjoying the tutorials. We're trying to be more consistent with our videos. We aim to post once per week but not fewer than twice per month. All the best Lui!
When I hit render I dont see anything the render screen just stays black. I am using Houdini Apprentice so I dont know if it could be due to a resolution limit and if it is how do I adjust it?
Does this "Houdini Failed to save output to file "Traceback"" appear on the render view? if it does, this happens when you have non-latin characters or accent in your user profile folder. I had the same problem, search "how to rename user profile folder" on google. it worked for me! good luck!
Nice video! BUt just a question about HDRI. Anyone knows why the warning 'mantra: Unable to load texture ' appeared when I gave a HDRI file to environment light? 😥
Hey.. While rendering I am getting redn and white colors of sprinkles. I hav multi color in scene view for sprinkles. I am using Hudini Free version to get used to it. Can u help ?
You've got ‘DYNAMIC_SPINKLES’ display flag enabled. Just turn off the blue flag and you should only see the tube particles. Having ‘DYNAMIC_SPRINKLES’ displayed with also render a second version of your particles, but without tubes. By default, mantra will render these particles as spheres.
The Environment Light only works in the viewport, not when rendering for mantra. Also my shadows between icing and dough don't look smooth. Any Ideas? I'm using Houdini 19.5
Loved the tutorial man. I am having a doubt. The icing isnt visible in my rencer view. also the sprinkles are in white and red color. Can you please help me with it?
Hey, one thing to check for your icing, is your display flag. There should be a blue display flag on the icing object. For the red and white sprinkles, it is likely an issue with your attribute randomize. Check to make sure that your 'Distribution' on the attribute randomize for Cd is set to 'Uniform'. If that doesn't fix it, try downloading the file in the description and compare yours to the downloaded file. If you're still having an issue, let me know :)
@@NineBetween I dont know if Pranil's sprinkles are rendering like red/white spheres as well while it should be a tube... but for the love of god i cant make it work lol I went through and through, comparing your file with mine and I didnt see anything amiss... and I know it's probably something really stupid that I didnt do...
@@heyLevii I had this problem too. Seems to be something to do with it rendering everything. I think it was rendering the dynamic sprinkles on top of the new sprinkles. This is a hack fix, but where it says 'obj' for your network, click it and go to 'out'. Click the mantra_ipr node, go to the 'objects' tab, and in 'Candidate Objects' click only 'Sprinkles', 'Icing' and 'Donut'. Get rid of the *. See if that works.
I'm having an issue with my render time (in the render preview) rendering just one frame. I'm running a Ryzen 9 5950X, 64 GB Dominator platninum at 3200 mhz CL16 and an RTX3090 but when I want to render it's giving me an ETA of almost 3 hours (resolution 1280x720). If I remove the purple background from the scene it has an ETA of 5 minutes. I tried lowering the resolution to 640x360 but still have an ETA of 40 minutes I'm working in Houdini apprentice 8.5.462 if that would make any difference. I mainly use C4D at the moment and I'm getting no where near these kind of render times when doing something similar there. So I'm looking for tips and advice on where to start looking for the cause of these long render times. Thanks in advance!
Found the solution to my problem. After converting the HDR file used on the environment light into a .rat files it rendered in just a couple of seconds. Credits go to: www.reddit.com/r/Houdini/comments/lo55kt/2_hour_long_renders_for_very_basic_scene_in/
When I render, the render is upside down and the particles are spheres instead of my cylindrical sprinkles... Why? In scene view it looks fine... The sphere's are basically the dots from the dynamics but I don't understand why they get rendered (they get colored grey while falling and red when on the icing)
I needed to change the "render visibility" of my "dynamic sprinkles" to be "invisible"... The upside-down image, idk why that happened, but I reloaded and replaced camera and lights and seems to be fixed.
I accepted HDRI in the enviroment light.. but there is no change of background ..but after I did render I can see there a subtle change.. in that case was the HDRI accepted on my scene? sorry for my english..
Could you let me know how to improve the render speed? My computer(Mac pro 15) is a little slower than your render. Is that fine I buy new computer meet the minium specification written in houdini website?
Hey, your Tutorials are so simple , Thanks a lot. But in this rendering session... I have followed as per u said, but when i click render.. i m getting many White balls falling and balls which touches the donut stays red .... Can't fix this..Pls do reply
i am having trouble while rendering which says Invalid detail specified Invalid detail specified Invalid detail specified [20:27:53] mantra: Can't find geometry /obj/Donut/Donut_out [20:27:53] mantra: Can't find geometry /obj/ICING/Icing_out [20:27:53] mantra: Can't find geometry /obj/toppings/topping_out. Can you please help me out
When I render I am getting spheres instead of tubes(I don't have spheres in the scene) that too very large compared to what I have in my scene..any idea what might be happening!?
Hi, generally, if you're trying to render points without any geometry they'll render as spheres. It's houdini's way of dealing with particles. The size of the spheres is dependent on the pscale attribute. So, check two things, is your display flag on your tubes and do they have pscale attributes? If you'd like, the file download is available to compare :)
When I download your part 3 file, the sprinkles are going through the donut. 'Add Hit Attributes' is checked and popcollisionbehaviour is on stick. Why does this happen??
houdini failed to save output to file traceback (most recent call last) i have this problem when i render... seems like it has to do with the environment but all my folders are name correctly any ideas?
Hello Sir, I have a problem in render view. In scene view everything is perfect but when i go to render view , the sprinkles (Tubes) turns into spheres . Please help why it is happening.
Hey Manu, usually, if spheres are rendering in your scene, it is because your particles do not have geometry attached to them. Make sure that your display flag is on the last node of your sprinkles node. Also, make sure your DYNAMIC_SPRINKLES node is hidden. It will render as spheres if you have it showing. Otherwise, try downloading the file that I linked and try comparing. Hope that helps!
Hello! I hope someone still watching this but... does anyone had the issue with the icing? I can´t see it when I´m rendering, I solve the spheres Issue but man, I don´t know what to do D:
Hey! In houdini, points are rendered as spheres. This just means that you have not copied any geometry to the sprinkles points. Check to make sure that your render flag is on the correct object and it should work. I hope that helps👍

go to your dynamic sprinkles geometry, and press the blue flag on the transform node
Thanks a lot.. it worked.
@@diftyfifty If random color was defined in sprinkle node why happens this way?
for some reason the scene feels very choppy in my computer. Like I just bought a new one with 32 gigs of ram and 4070 Nvidia graphics card.
Where do we go to add more sprinkles that get stuck to the icing? Right now mine are scarce and spaced out
Dynamic_Sprinkles > popnet > POP Source and then adjust the constant birth rate.
tank you man
i am having trouble while rendering which says

Can you please help me out
Hi, my render tab stuck in black (I add camera and light) What should i do
i love you bro 🙂
When I render I am getting spheres instead of tubes(I don't have spheres in the scene) that too very large compared to what I have in my scene..any idea what might be happening!?
Hi, generally, if you're trying to render points without any geometry they'll render as spheres. It's houdini's way of dealing with particles. The size of the spheres is dependent on the pscale attribute. So, check two things, is your display flag on your tubes and do they have pscale attributes? If you'd like, the file download is available to compare :)
On the dynamic_sprinkles geometry check the display/render flag on the transform node! Tell me if it worked!
@@fabiogomes1145 Yes it is. Thanks, but why?
@@NineBetween This is also happening to me and i tried your file and it still happens
@@fabiogomes1145 omg THANK YOU!!!
when i am rendering the sprinkles the tubes become the sphere please help me
When I download your part 3 file, the sprinkles are going through the donut. 'Add Hit Attributes' is checked and popcollisionbehaviour is on stick. Why does this happen??
houdini failed to save output to file traceback (most recent call last) i have this problem when i render... seems like it has to do with the environment but all my folders are name correctly any ideas?
Help when i render the springkle become a sphere
my icing top layer is not getting rendered any idea why??
Hello Sir, I have a problem in render view. In scene view everything is perfect but when i go to render view , the sprinkles (Tubes) turns into spheres . Please help why it is happening.
same happened to me :(
Hey Manu, usually, if spheres are rendering in your scene, it is because your particles do not have geometry attached to them. Make sure that your display flag is on the last node of your sprinkles node. Also, make sure your DYNAMIC_SPRINKLES node is hidden. It will render as spheres if you have it showing. Otherwise, try downloading the file that I linked and try comparing. Hope that helps!
Hey, I gave Manu some feedback, maybe it will help you. All the best!
@@NineBetween woo! thanks, that would have been a tough one to figure
@@NineBetween had the same issue but you were correct my DYNAMIC_SPRINKLES wasn't hidden
Hello!
I hope someone still watching this but... does anyone had the issue with the icing? I can´t see it when I´m rendering, I solve the spheres Issue but man, I don´t know what to do D:
"see you next time!"
@Nine Between hi,I have some problems to ask you,when i click render button,then just stuck on "generating scene" ,how can i solve that
same, check if the folder name has some weird letters in it
:-* Love you sir
Is it normal to see your Sprinkles rendered out as red circles? (Can somebody help me with this?)
Hey! In houdini, points are rendered as spheres. This just means that you have not copied any geometry to the sprinkles points. Check to make sure that your render flag is on the correct object and it should work. I hope that helps👍
My Donut is like super bright lool
when i render it gets flipped any help?
why is my render upside down
Same here. Even pressing H in the viewport does not help. Does anybody know how to solve this problem?
Pressing H solved the problem as i remember.
idk why but when i am rendering it doest showing the sprinkles its showing red and white balls
