I am currently working on my first mod for BeamNG, and right now I'm trying to load a .jbeam file as a test (I used rmikebaker's Blender to jbeam exporting tool). My vehicle appears in the vehicle select, but once I attempt to load it, the game shows a loading symbol for a second, crashes, and displays an error box. (Error 0x00000001) I tried loading it again in safe mode, but the same thing happened. Has anyone else had this issue, and is there any way to fix it?
That tool does not export jbeam from the model, you have to make nodes and beams in Blender, which can then be used, but it does not generate beams automatically. If you export the model as a jbeam that will be just useless file with lot of nodes and beams without actually structure that nodes and beams require. Even if you carefully craft node and beam structure in blender and then export it, I believe you have to do lot of editing by hand in text editor.
