Thanks for all the feedback so far, everyone. Please upload a picture if you can. The driver camera being off center is intentional, the seat of a racing kart is offset to the left slightly to compensate for the weight of the engine on the right. (source: Gli ANNI D'ORO DEL KART Facebook) I know about the moving props (steering wheel, driveshaft, and pedals) disappearing already, it may be a bug due to the props being part of the main JBeam rather than being part of a slotted part in the Vehicle Customization menu. Breaking up the main JBeam into parts (Main jbeam -> chassis -> seat, engine) may fix the issue and I've already planned to do that. It was a mistake to put everything under one JBeam file but this is my first mod and I'm learning as I go! As for AI cars passing through each other, the kart currently doesn't have collision triangles on the frame. Once I add them, it should fix inter-vehicle collisions. The missing floor just needs a material flag that I forgot to set, so that will be fixed. I haven't yet figured out how to get the RPMs to display but I'm sure it has something to do with the powertrain.
