Int to color conversion is missing (you may notice error message in log "Error| * Unsupported socket connection at "/mat/integer": VOP_TYPE_INTEGER => VOP_TYPE_COLOR!").
I'll fix this.

Anyway... if the input is not "int" just use "User Float", all data is exported as floats anyway.

Ah, good to know, it works. Thanks!

I have the same problem (I would like to drive the attribute to switch different textures in material context)... Was it resolved?
Thanks!

Hey woytha ,

could you please check if the file attached here works for you ?

Yep, that works! I was using Houdinis native switch which seems to not accept the values from vray float / integer node. With vray multiIDtex node it works just fine.
Btw it kind of confuses me that Houdinis material nodes seems to have problems to get work with Vray (especially as I am migrating from Maya where it was just fine if I can recall correctly).
Anyway thanks a lot.

Hey woytha ,

It is indeed the case that V-Ray in Houdini does not support the native Houdini nodes. We could have tried emulating some of them with V-Ray plugins in the background but that would mean we would only be able to cover some of the nodes, and only some of the parameters. This would eventually lead to a lot of confusion for everyone so we decided to stick to supporting V-Ray nodes only.

Hope that helps!

I see. It would be helpful to somehow block / or announce that it is actually not supported. This is rather confusing for new users (or migrants ).
Anyway, thanks!

If you are inside the vray material builder and press tab you will only get the ones supported.

There is also an option to leave only particular renderer nodes in Houdini: Edit -> Preferences -> Rendering.
