Hi Christian,

I'm not sure what version of Chimera you are using, but with the current daily build, the VRML export (File / Export Scene...) does include transparency of surfaces. I believe older Chimera versions (1.3, ...) also do this. I made a transparent red icosahedron and writing as vrml

shape icos div 1 color 1,0,0,0.3
export format vrml ~/Desktop/test.vrml

The resulting vrml text file does have the transparency information, and when I open it in Chimera it is transparent (although Chimera does not display transparency of VRML models correctly). So quite possibly the program you are using to read the VRML is ignoring the transparency.

Hi there,
I am trying to export molecular surfaces with varying transparencies to vrml, but the resultant model has a completely opaque surface. Is there anyway to export surfaces with transparent features to a 3D model? I would rather not work with x3d files as there don't seem to be any good 3D modeling programs that can accept this format.

Thanks in advance,

Christian
