[PyMOL] Ray tracing transparent sticks

[Ioannis R. <riz...@eb...>]

Hello!

I have been trying to ray trace stick representations with transparency (i.e. stick_transparency = 0.5). Although surface transparency is visible in ray tracing, transparent sticks always appear opaque in the rendered image. 

Is there a way to resolve this? Note that in OpenGL, stick transparency appears normal; the problem is only in ray tracing.

Thank you very much.

All the best,
Yannis
