(Resolved) UV shader mapping

[Jim Meston]

Hey all,

Sorry for the dumb question but I am stuck on achieving a simple task, UV mapping in the shader level.
Is there a way to cylindrically map and have have some kind of size controls?

I can see camera settings but I do not want it to be a cam projection.

Best,
Jim

You could use MakeTransform VOP to control size of Projection UV with type Cylinder. Check the example bellow if it will work for you.

Oh so you can use Houdini vops in a vray shader ??
Which other ones can you use?

There is a projection UV node with cylindrical projection type.

Well I think, only MakeTransform VOP is supported, at least can't think of another.

Yep I got that far, I was just struggling to do more complete uv transforms at shader level. "MakeTransform" usage completely solves this for me.
