Now in UE 5.03: I have a wheeled vehicle pawn using a skeletal mesh that was a Physx UE4. I have successfully converted it to chaos including the skeleton, wheel blueprints, it drives perfectly. It just looks wrong when I drive it in the game. If I just drop it into the Level it looks fine. If it is not active (just leaving it there dropped into the scene) it’s totally fine. But when I make it the active player its just wrong. It’s all black and strange no matter what material I select for it. It looks like maybe it is inside out. I have no clue as to how to fix this. Please see the pics below. How it looks in the editor just dropped into the scene (white), and then while the game is simulating in the viewport (its a weird black).
Ha, just after posting this I figured it out. Looking at the Reference Viewer I found a reference to an material I didn’t think I was using. As it turns out I had copied the Wheeled Pawn blueprint from the Vehicle example project the and function for the brake lights was applying a material to mesh for the car. Very weird and not at all obvious (until now)
