Will jPCT-AE support "OpenCollada" like it supports "3DS", Blender has great support for import and export of "dae" files. I say this because OpenCollada/Blender has great support for UV maps on an object.
I see the bones add-on to jPCT has some OpenCollada support , but don't know if it works in AE and don't need all the other stuff it adds "yet".
