[Chimera-users] VRML rendering options?

Hi, I have been using Chimera for a while and find it great software. Now I am trying to include my own VRML models and show them together with PDB data. I succeeded in opening an externally generated VRML 2.0 file. Since the VRML file contains colored boxes, the standard smooth rendering is not appropriate. Is there a way to influence the rendering style? Also, is there a way to switch on a fixed transparency (alpha value) for the whole VRML model, on a per-model basis? Any help would be appreciated! Cheers, Nils
