Does it “work” with one of the glasses? Transparent surfaces make Tachyon do *a lot* more work. Depending on your settings, it can take quite a while to render, especially with CPUs only, like it would be on a Mac.

Subject: vmd-l: VMD Tachyon Render fails with new material

Hello VMD Community,

I am trying to use VMD to visualize a membrane protein. I have output from the HOLE2 program which lets me visualize the tunnel inside it. To visualize the tunnel better, I use a surf representation of the protein and make a new material with lesser opacity. When I try to render it using Tachyon/Tachyon Internal, VMD stops responding and I have to end up closing it. Rendering works when the material is one of the default ones (Opaque, for e.g.). Any insights would be appreciated.

I am using MacOS 10.15 (Catalina) and VMD 1.9.4a51.
