[chimerax-users] request for true transparency support in .bild files

[Francois Berenger]

Dear chimera hackers,

In the old Chimera (not X), if I put two transparent spheres in a .bild 
file:
one sphere can completely hide the other (e.g. a small one inside of a 
bigger one).

While, if there was true transparency, no sphere should completely hide 
another.

Is this better handled in ChimeraX?

I _love_ .bild files, because it is so easy to generate them in order to 
annotate
a 3D molecular system then view all of it (molecules + annotations) in 
Chimera.

Thanks a lot,
F.

PS: here is an example problematic .bild file for the old chimera
