Hi everyone,

I'm making a noisy shader in vops and I need the noise to “stick” to the object if it moves. I've done a “uv project” on the object at the sop level. I know that I can get in s & t and put it into a texture vop, but I don't want to use a texture map. If I leave the texture map field blank, it renders reddish. Is there another vop I can use that will take and use the s & t?

Thanks!

Sure, “Anti-Aliased Noise” will pay attention to s&t - in fact pretty well anything that uses “P” will. Ensure you've placed a “Shading Layer Parameter” VOP, and feed that into your Pos input of the AA Noise. That will respect any s or t changes you make back out in the UVProject SOP.

The reddish result you got is when mantra can't find the image you've said you wanted to texture map. That's expected behaviour - you've said you wanted a tmap and didn't provide one. It really depends on what you wanted to create in your shader.

Cheers,

J.C.

Thanks, that was it!
