I am new to Substance Painter and have some questions.

Before exporting from Maya do I have to always put lamberts to objects to separate them or can I just use collage UVs? If so how can I work with collage UVs in Substance Painter?
Thanks in advance!

collage UVs?

ionicotaco

yeah like put a whole model in the 0 to 1 space or just separate the UVs by materials
Want me to explain it with pictures?

If you are using UVs, then all of your UVs have to be in 0 to 1 to texture in substance painter.  Although I think Painter now support UDIMs.  If you want pieces in separate texture sets within Painter, you need to assign different shader in maya.  You can also separate areas within the same texture set using an ID map.

Yes that is what I mean. But if you don't make separate pieces do you just use masks to put materials in certain areas?

The color ID map will allow you to apply different materials to different areas.  If you need to use more materials then your color ID map supplies, you can always create more masks manually in Painter.  I usually do all 3: color ID map, texture sets, and some manual masking.

Ohhh well thanks for the help. Appreciate it!
