It only seems to happen with this truck, I don’t know if it’s some weird setting in 3ds Max or what, but I’m pretty sure it’s the skeletal mesh and not the engine itself. When I import it into modo it shows the skeleton at 100% and the truck at 26% scale, I’m pretty sure that’s causing the problem. Though no matter how much I change the skeleton or the model and zero everything out, It still imports the same, so I assume it’s something on my end.
