UV randomize + Triplanar = doesn't work

V-Ray V-Ray for Houdini Issues
1

Hello.
I want to use UV randomize and Triplanar, but seams it’s doesn’t work together or I set-up it incorrect. Please check screenshots below. Also maybe you can make using triplanar similar to 3ds max when I plug it Mapping sourse and can have only one Triplanar node for all maps in the shader? I use Houdini 19.0.455 and vray_adv_52020_houdini19.0.455_4c01e64_2201 from Nightlies

Hi @Mikhalenko , can you try using embedded randomizer in UV tab of ImageFile VOP.

Hi I will try. Any info about using 1 Triplanar for all ImageFiles?

This particular 3dsmax setup is not supported. It could be implemented, but it’ll take time.

It’s not exactly the same but you could use “V-Ray UV Projection” uv generator in “TriPlanar” mode in uvwgen input of textures.
