Large ocean render in Houdini with Vray

Recommended Posts

Hi everyone,

I apologize in advance if this is not the right section to post this.

I'm trying to find a solution to use Houdini Ocean Tools in Vray. I have the basic scene with the giant grid, which in Mantra is displaced at render time. At first I connected a material node with a basic Vray shader (without any displacement) after the Ocean evaluate node (I know that I will have a gigantic grid with many subdivisions but that isn't a problem) but it doesn't seem to pick up the full displacement value. Then I tried to export the textures from the Ocean Evaluate node but I'm having a problem with the displacement in the Vray shader. Has anyone ever achieved a realistic look with HOT in Vray? 

Thanks for the help

Hi Lucky card.

 

The textures file loadeder has a bad filter set which makes the displacement look blocky and clipped.

Change it to Quadratic from Bilinear and this should fix the fiirst part.

Second in under the Vray displacement node, check Use Bounds and set the black to -4 and the white to +4 and you should get a faire match.

 

I hope this helps, vfxamp.
