Hey guys! I am new to both modelling and modding, so i really don't know what i am doing that much. So i made this model for a custom vehicle. Looks good in blender, i export it in game go to the asset editor and see this: (it's shadow looks like a cat so that's cool i guess.) Before this one i couldn't even load the model so this is progress but as you can see i need help. Below there are two images one is a render of my model other is kinda the properties and stuff. I also wanted to attach a blender file but it won't let me, sorry Thanks in advance!
