Hello,
I just saw on the blog, that we can activate threads for the rendering in panda 1.8.
I just tried to pu this two lines at the top of my program
from pandac.PandaModules import loadPrcFileData
loadPrcFileData("", "threading-model Cull/Draw")But error:
:display:gsg:glgsg(error): at 3436 of c:\buildslave\dev_sdk_win32\build\panda3d\panda\src\glstuff\glGraphicsStateGuardian_src.cxx : invalid operation
:display(error): Deactivating wglGraphicsStateGuardian.Can you help me?
[/code]
Does that happen when you just have a trivial program that imports DirectStart and calls run()?
If it doesn’t, but it does happen in your larger program, maybe you can determine what it is that your larger program is doing that triggers this problem?

It does’nt happen on a such simple program.
I am using a program using bullet. I think it is the only things that can be impacting.
