I used this on a model I made (1 group) and the game crashes without an error message :| Jbeam is attached if you want to check it out. Also seems to detailed atm
Thanks! For a future plugin, you should make a script where the selected nodes (in Blender) would be connected in a way so that they would support in BeamNG, like something that connects each node every possible way when you run it. That way we could make the rigidness of the vehicles quicker, and maybe even better.
