[Chimera-users] Exporting from Chimera to Blender - basic questions.

Hi Andrew,

  Chimera exports the surface vertex and individual atom and ribbon 
residue colors in the X3D and VRML output.   If you raytrace a scene 
with Chimera File / Save Image... it first exports X3D and then converts 
that X3D to input for POVray which does get all the colors right.  So I 
think your question calls for some expertise with Blender, to find out 
what color information it can handle when importing those files.  I 
don't know anything about Blender.

> Hello all, 
>        I have recently solved the structure of a novel membrane protein, and have been using chimera quite a bit for my figures and analysis. In my free time I have been playing around with the 3D animation package Blender which I must say is a total blast, and makes fantastic movies and animations. However exporting from Chimera to Blender is a little tricky, in that when using VRML2 or X3D formats while the actual 3D "mesh vertices" import quite well, the colors are not imported, and imported items such as cartoon helices seem to have totally random materials assigned to nonsensical segments (instead of materials assigned by chain for example) . Ideally I would like to perform and export the coloring operations using chimera because it's obviously an order of magnitude easier to select residues, chains and monomers with chimera. Or at least have the grouping of objects imported correctly. This is really just for fun so I'd thought I'd ask if anyone here has any experience !
