Hi Matt, Yes the VRML lighting is handled differently in Chimera than lighting for molecules and density maps. As I mentioned before, our VRML implementation is very limited. I guess this includes bad lighting, but I haven’t seen examples. You may want to send an image so we know just what you mean by “lighting drops off”. I have certainly seen many examples in the past where VRML transparency in Chimera looks very bad. Tom On Feb 12, 2014, at 12:35 AM, Dougherty, Matthew T wrote:

I have a multiple vrml models that vary by scale. 1, 10 & 100

I notice the lighting significantly drops off as the scale increases.

When I have another model, say PDB, that is in approximate relation (ie, viewable in regards to the volume size similar to the vrml files volumes); the PDB file looks good regardless of size (eg, tRNA or ribosome).

I can increase the brightness to compensate (10-20) but it washes out the PDB models when brightness goes beyond 2.

is the lighting handled differently between these different types of models?
