Some dmx happen to have "duration" key word exported, despite not meeting version condition in code. Ex. L4D2 animations DMXs included in starter kit.

They are sorta like spheremaps

Downgrade to more appropriate version

Or update blender

Maybe reparent that barrel thing bone to gun bone. Cuz those freely moving bones always suffer from precision loss.

Jitter graph modifier?

If you provide an engine, path, the exporter will automatically select the correct DMX version for you.

I specified engine path, exported. Studiomdl can't compile, ACCESS VIOLATION error.

It scene tab

Exactly what it says
