Major premise: this is probably a very, VERY simple problem with a very obvious solution - I am a beginner with both Blender and JBeam so I could really use some guidance. Bear with me! I'm trying to add an alternate shell for this vehicle, originally a RoR truck converted for BeamNG.drive. I adapted a replacement body mesh designed to sit on the same chassis and imported it in Blender. I literally slapped it on top of the existing structure, together with the current body shell: Now, this is how the new shell spawns in game... ... and it doesn't seem to be correctly attached to the chassis either (despite the grouping defined in the flexbodies section of the body file). The shell movements seem to be... mirrored: if I turn the vehicle to one side, the shell seems to lean to the opposite side: I feel I must be missing something blatantly obvious yet very important, but I don't know what it is. Thanks in advance.
press c+a you should get this click on rotation and scale in the bottom left check all 3 boxes then export
... ... and now I feel VERY stupid. It was much simpler than I thought, I could have well figured it out... Thanks a heap bunch!
