Re: [PyMOL] Shader issues and automatic disabling (was Re: I just built pymol, comes up but hangs on any attempt...)

[Jason V. <jas...@sc...>]

Hi Ben,

We read the shaders from $PYMOL_PATH/data/shaders. We should be
reading them from $PYMOL_DATA/shaders. If you'd like to change this on
your own compiled PyMOL you'll need to change lines 411 and 418 of
pymol/layer0/ShaderMgr.c and rebuild. If you're a paying PyMOL
subscriber this should be fixed in the next update release. This might
not be the problem for you, though?

What is your $PYMOL_PATH set to? What is in there when you do a file
listing of that path from the shell?

Cheers,

-- Jason
