10:32 treat object as volume 20:30 setup no primary visability (only bounced / reflected etc). 21:10 velocity v - velocities color Cd -> displayColor 25:65 render as holdout 30:05 render as discs
If anyone is experiencing that bug at 11:45 where the ocean becomes blank, go back to the ocean geo node and save the spectra to disk again. I do not know why they removed that part from the video.
I have the problem, that I only see a flat grid without my spectrum although it should be applied. Ive been struggling with karma ocean issues for 20h straight in total. So Im a bit frustrated. I watched so many videos. Every video about karma oceans including masks etc. I need to increase dicing a lot to even see my ocean spectrum. However, no matter if a grid works or not. I need to apply the spectrum on a flip mesh which also gets masks etc. That ends up in a long long long initialization, so I consider mantra faster at this point. But even if I try mantra is continuously saying "processing displacement geometry". So I decreased my spectrum resolution although I even tried this in karma before + packed my flip mesh. What should I try now? Any ideas? I would really appreciate any tiny bit of help.
No cameras found in the USD file Anyone else having this issue when trying to render to disk? Renders fine in hydra and the camera IS in the stream. Thanks for a great video! Edit: Resolved itself when updating to 455.
Amazing tutorial, such valuable information, I've being creating shaders on material x for flip ,white water and oceans, with XPU now simulations are blazing fast. i got everything working properly except the volume gradient for specular, any tips would be really appreciated.
How much gpu memory is required to render a more complex scene(including explosion and oceans) or like kingkong vs skullcrawler final battle.with gpu alone.is 16vram enough? @rebelway
-How come the ocean shaders become a simple diffuse glossy shader when imported to K? There's not even as many waves as Mantra -Why is dicing not an available option in RenderGeometrySettings -Why is the lighting completely different in K compared to M?
We are going to focus mainly on Karma, however everything should be applicable you just need to find the appropriate shaders for your third party renderer.
Great stuff..actually my intention was to see the creative aesthetic side of your developing a water/WW shader when using renderman.I quite liked your videos with Arnold volume shader construction so always on the lookout for your other valuable inputs in terms of aesthetic designing
@rebelway really loving this and felt very straightforward but had some issues with glitching geometry and volume when rendering out to disk, experienced anything like that? any good tips on what to avoid?
I had some glitches too. For example, one frame would ignore the fluid and volume and render only the whitewater volume. Then the next few frames would ignore the whitewater and only render the fluid elements. The final render looked like a strobe effect switching between whitewater and water. The object stayed constant.
@@MarvelousMediaEngine hey if you have this issue I solved it by rendering points as uniform volume - rather than using the rasterised volume, which I would have preferred.
the scene files link isn't working at 9:30 you set the sop import to read ocean interior/merge render grid - this is not available if i create the ocean from the shelf,
Does anyone know how to bind the vorticity and velocity to basecolor if you are using the shelf generated basic liquid material. I see how he binded them into his coreshader, but the default liquid shader that is created with the shelf tool looks so much different.
Wow... Mind is blown... Now a small request. Can we please get a tutorial How to make Cinematic Quality Spiderman Web shooting simulationd. COMPLETELY PROCEDURAL? There aren't any on TH-cam actually. it can be the first... Thank you...
Do you guys think you could make this tutorial but for MaterialX. I really want to render on my 3080 and my 10700k has a hard time with volumes. Cheers
Well I tried, it's definitely not for everyone. Still very slow on my CPU, kinda enjoyable on XPU with some previewUSD shader, I don't know what else I could use; many things doesn't work with XPU so without a very powerful CPU I'd better give up on this
big fat beefy cpu and lots of ram ought to do the trick, also a bigger hdd or ssd wouldnt be bad, and while youre at it you can also upgrade your gpu. basically if youre asking these types of questions youll probably need to upgrade your whole rig lol
Hey I've opened your project and the water is pink and I don't know why does this happen to someone else?. It appears this warning: Load warnings for C:/Users/(name)/Downloads/Ocean Rendering with Karma Project Files/water_shading_in_karma.hipnc Warning: Problem while synchronizing child node: Warning: Problem while synchronizing child node: Warning: Skipping unrecognized parameter "firstpointcount". Skipping unrecognized parameter "firstprimcount". [/obj/ocean_surface/oceanfoam1/foam_sim/pop_object_foam/sopsolver1/attribwrangle1]
SOLVED: in a recent version they did some cleaning on the sopsolver1/attribwrangle1 node thus there is a unrecognized parameter. you can delete that popobject node and rebuild it since you probably updated your H19 version while the project is older.
I can’t believe I’m watching this for free

Very welcome!

Hi, great tutorial. but the download link to project file is dead. any chance to update the link? Thanks
Thanks for sharing. Always wanted to learn more about Karma.
Now please make some destruction very detail tutorial and render it in karma.
You are a great houdini school
Brilliant work!
These guys are content machines!
omg you actually did it
We don't have plans for third party renderers, main focus is going to be Karma, Good luck!
Wow, thänx for this great tutorial AND for the scene files! Amazing!
You're very welcome!

really good tutorial, bad project files is not available and it is really hard to repeat if you don't know what is inside attr VOP and Wrangle
Beautiful
Thank you so much!
Great video, i like it 😊 Nice simulation, you use the tool in a very talent way.😁
I've been waiting for this, thank you so much!!
No problem!!
@@Rebelway Hi, you mention to watch Karma arrow scene before? Which one is it please?

doing well and thanks again!

Really awesome tutorial! Any reason why you didnt use the MaterialX shaders for this? Or is that not supported for this use?
I need a materialx tutorial lol
@@oxvcontent1040 me too apparently, all my mtlx creations are lacking
@@iluvyunie yeah I just switched to redshift

coooooooooooool :)
for the materials, what do I set "usd path prefix" to?
is there any cources about the whiter water with xpu render in houdini 20?
Downloaded the Project Files but I cannot find the HDRI tex "Cloudy_Sun28deg_etc.rat"'. Anyone experienced the same issue?

@@timtaxevasion then i guess a ryzen 7 and a Quadro p2000 not enough 🥲 how can a 15 year old but a 128GB ram and a RTX 3090 and threadreaper
how much did it took to render this clip? time!
project file isnt in dropbox anymore
How many disk space used?
those repeating pattern at the beginning is ....😳
想问一下 我用houdini 20做水的特效 ，和houdini19相比有什么不同吗
i would like to know that i only have 64G RAM , is that enough to do this shot?
yes, very much yes
why don't we use XPU????🤔
Does XPU works? how much render speed imporvement?
no XPU for these VEX shaders
🙌👍🏻👍🏻👍🏻
Can some one tell me what is the recommended spec of computer to do this shot.....???
We recommend using a computer with 32gb ram, but you are able to still use it with smaller than that. It just will take longer. Cheers!
@@Rebelway Thank you very much, And a little question : The high end CPU and VGA do help that or not ?
WHATS YOUR PC SPEC?
Show how to render it with arnold.
they arent planning to sadly :(
god bless u xdd
have too many proprietary restrictions on the user and I want more freedom in importing and exporting projects, soft and video editing
How can i get Houdini for freeee?????

Try saving the render grid, it's probably looking for the displacement map
