Baking Maya projection to multiple UDIMS

Chris Rohlfing · Sep 2020

Hey all I am trying to bake a projection texture in Maya to the multiple UDIMS for a large roadway I am doing. I have tried "Convert to file texture in Hypershade but it only does the 0-1 space. My ultimate goal is to get this into substance painter.

Why don't you bake it in substance painter?

I would but there dosnt seem a good way of matching the projection exactly in Substance painter with the scale and translation of the projection in Maya. Currently I have the projection matched with a meshed point cloud of the site in Maya. If I were to do in it Substance painter it would have to be a 1 to 1 match for the projection since accuracy is important for the project. It's being using in a civil case.

Cut the geo and move all UDIMs to the 0-1 space. And bake them one by one.

I think turtle could also work.

Nice, I had no idea Arnold had this. I think this will work. Thanks for pointing me in the right direction. I got it working earlier by having to manually move all the UDIMS into the 0-1 space but that could end up being a pain on future work with more UDIMS. Again thanks going to try this now.
