What if I wanted/needed my model to have more than two UV I've never seen more than two UV for games ?
I can't imagine how game making could be lot more complicated with one more UV
Well it's just an appart remark.
Unreal Engine 3 supports 3 uv-sets (for color, light map and I forgot about the third
).
It reads ASE and Collada. And it supports some special export plugins.
Currently many engines thend to support Collada (C4, Torque, Shiva, Unreal 3, Unity, S2, XNA ...). FBX is another choice. But Collada is more open, you can read it easily, like a XML file. FBX is property of Autodesk and you get "only" a SDK.
Both formats are able to store geometry, several uv-sets, cameras, animations, bones, lights and more. Colldada can even store data for physics and shader.
@AlbertoT: Yes, it can happen that FBX or Collada files work fine in one engine but do not work perfect in another. Each implementation of exporter and importer can differ.
