Hi!!

I'm trying to render a ocean scene, with foam, ocean spectrum, flip simulation etc, but the render with karma_CPU shows different colors, in my case, red colors for ocean, flips and foam. This happens in H_20.
My scene is different to this, but for test the materials, light etc I've tried to render this project and I've had the same result. I attached an image.

The material are done with VEX Material builder and with karma XPU I don't have any render. I don't know if VEX material builder is not compatible with karma XPU.

Hi!

I have similar problem with my unreal and the heightfield HDA.

I have my layers (volumes) in houdini and I create the HDA.
Then I import this HDA to my unreal project and finally I add the HDA to the scene. The problem is the landscape object is not nest/join to houdiniassetactor and if I check the layers in landscape/paint, there is no layer and when I use the material by layers, the terrain is black.

I have watched a few tutorial about how is the best way to import a terrain_HDA into unreal and in all of them the landscape is attached to houdiniassetactor.

Any solution?

Jajaja. Don’t worry. Feel free to discuss about everything related to the topic (new pc). It is also additional information for me.

Ok! Thanks for your information!! It was very useful for me

Thanks for your reply. Im waiting for to know the price of the 3d version and then I will choose between this one or the 7950x.

About the graphic card, I know the best solution is 4090 but the price is very high. I dont know if the amd solution is a good solution for houdini. Nvidia 4070ti, 4080 or 4090, depending on my budgetary, are the best devices.

hi,

I’m thinking to update my current Pc and I don’t know which processor is better for houdini.

Intel 13900k
Amd 7900x
Amd 7950x
Amd 79003d vcache
Apple silicion (mac pro/mac studio).
My preferences are amd or apple. I don't know if the 79003d is just dedicated to gaming and I don't know if there is much difference in performance between the 7900x and 7950x either.
Currently I have an amd 3900x.

Thanks!

Hi,

I'm introducing in the heightfield world and I have a doubt regarding the shading workflow.
I have my scene, heightfields, terraces, noises, distorts, masks, trees, etc etc etc but I don't know if it is better to shading the terrain directly in houdini material network (or shop), exporting previously the masks, displacement etc or using substance painter.
What is the diferences between doing the shading in houdini or in substance painter? I think in both cases I need the terrain (displacement) and the different masks (debris, water, cliffs, sediments...). If I need export anything else, please indicate it.

And finally, for the trees, rocks, grass etc I think using quixel, the best way in this case is shading these items directly in houdini.

I'm going to use redshift.

thanks in advance.
