Creating UV id maps

Recommended Posts

Hello!

I am in the progress of uv-mapping some stuff. Is there a way to create id maps in Houdini? This is needed because I want to export my object into substance painter and texture in there.

hi, you can create arbitrary attribute on geometry, read it in shader (bind VOP) and bake it into a texture from there.

Thanks for the reply. 
I am not really sure I understand what you mean. 

At the moment I have different groups with different colours that I've set but I am unable to somehow bake out the colors onto the uv's to create id maps.

Thank you so much for this!
When I try to copy what you've done in my scene it doesn't work, when I choose to look at the "id" panel I only get a black screen. However, when I import the same asset and uvs to your scene it works so I am kind of interested in what settings I am missing..

I am very grateful for your help :=)

Nvm I got it working thank you, I forgot to add the material with the bind to actually use the Id attribute!
