IndexError: list index out of range #66

Closed Germanunkol closed 2 years ago

Germanunkol commented 2 years ago

I've gotten the following IndexError a few times now. It looks like it has to do with a bunch of objects which are part of the RigidBodyWorld collection. When I delete that collection, it works. However, I'm not quite sure - sometimes it even works with the RigidBodyWorld collection still in place.

I can try to provide a minimal example if needed, just don't have the time right now and wanted to leave this here.

I will need some way to repro this. A blend file I can run locally would work the best. If you can simplify it, that would be ideal, but, if not, that still gives me something to play with.

Moguri commented 2 years ago

Closing due to lack of response and no repro. Feel free to reopen this if/when you are able to get a repro case together.

Germanunkol commented 2 years ago

Sorry, haven't gotten around to this, yeah. If I find some time I'll send you an example!
