[Chimera-users] Chimera output into Collada .dae file format

Collada is a triangle format, so I'd recommend exporting from chimera in 
either the OBJ or the STL format and then convert it that to Collada. 
Neither Chimera export is ideal for Collada, the OBJ format has color, but 
only does surfaces, and the STL format doesn't have color, but does 

The open-source program MeshLab can be used to convert STL output to a 
Collada .dae file and has some ability to add color.  MeshLab didn't like 
Chimera's OBJ output in my test case, so you'll need to find a different 
program for that.

So, sorry I don't have a better answer for you, perhaps someone else on 
this list has alternate suggestions.  I'll add a Collada exporter to the 
list of feature requests.
