Generating ST maps in Houdini


Recommended Posts

I did this lately, just plugged UV inside a shader into R&G and exported it as a color variable to an image plane.

 

However i was wondering how to deal with UDIMs?

I did not allow for values above 1 in U or V by subtracting the real UV with their floored versions before plugging into Red and Green.

For example, UDIM U coords of 3.6 become (3.6 - 3.0) 0.6 in my stmap giving the familiar red-green look.

Not sure though if this the right way, or if i should just allow values above one ?
