[Chimera-users] Exporting STL/COLLADA/OBJ with textures

Hi Elaine,

Ok thank you. DAE do indeed seem to render the colours properly as I can see them in Mac Preview, though seemingly not in other tools as you say.

I don't suppose there is any way for chimera to write the colours out as an MTL file since this seems to be the approach other tools take.

I'm not very familiar with these file formats, but it seems to have something to do with colours being applied on vertices but not faces.

Any more info you have would be appreciated.

Hi Joe,
As per the “export” docs...

COLLADA export includes colors but many readers do not interpret them correctly.
OBJ export is only single color per surface piece.
STL export does not include colors.
X3D, WebGL, ... are more complete and may include what you want.

I hope this helps,
