this is the bug:

base.saveCubeMap(‘test1#.png’)

yet saveSphereMap works … hmm i thought they used smiler methods.

error:

Cubemaps don’t work very well post-v1.4.2

They seem to specifically have problems if the shader generator is active in your script.

Josh said he’d get around to fixing it sometime but I’m pretty sure it hasn’t been fixed yet.

No i don’t have shader gen on… and I really need this feature back Josh please help me!

It looks like a low-level bug in glGraphicsStateGuardian.cxx. I’ll check in a fix for a future release, but in the meantime, you can work around it by adding these lines to ShowBase.py:
