can you export an obj with 2 UV channel for lightmaps?

ZacD · Jul 2010

I'm having issues with this with XSI, it seems like it always compresses it down to 1 UV channel when I export.

It depends on the exporter and the engines importer. A second uv channel is not standardized in the obj format unfortunately.

What the best format to work with then?

commander_keen · Jul 2010

What engine?

Unity

Cant you just import the Max/Maya/Xsi file? failing that .fbx supports multiple channels

commander_keen · Jul 2010

Yeah FBX. The unity site says it also will directly import XSI files.

OBJ is 1 UV set only. FBX or Collada work with multiple UV sets. You might have to set the material to use both sets before exporting, and possibly try an older version of crosswalk.

really? the .xsi isn't working.

What if I have the the UV's already set up? is there anyway to merge without loosing them?

Do they need to be merged? The Merge UVs button seems to merge set1 with set1 and set2 with set2

I got it working once, then I messed with it and broke it again, thanks for the help though, I'm sure I'll figure it out.
