Hi everyone! Just a small note on this (maybe this helps debugging further..):
- having just a .xsirtcompound in a workgroup plus an open/once opened rendertree when unloading is a sure crasher (you dont even need a custom renderer in that workgroup) - the PluginManager["Tree" & "Workgroup" tabs] doesnt update when you switch between workgroups with .xsirtcompound in them using python - when using events and python to Add/Remove workgroups the only ones that _never_ crash for me are workgroups containing only python plugins. Everything that has a DLL/SO in it crashes eventually in my tests. Still havent figured out what exactly triggers this. I was testing this with a script that switches between different workgroups on siOnEndSceneOpen. The exact same setup could crash on first "switch", could crash only after multiple "switches", could crash during the event, could crash after the event when saving the scene, could crash after the event when hitting the "Connect..." button in the PluginManager[Workgroups tab]. hope this helps Philipp
