Custom physic vehicle simulation! Project download included

Hey! First of all thank you for this project, i found your development videos on Youtube and it looks really good compared to the default simulation in UE4. One minor issue is that every time i try to open the vehicle blueprint, it freezes the engine, probably due to the automotive materials, which my PC seem to have some problem with. Is it possible to include a version of the vehicle with no materials on it? Or can I edit the blueprint with a text editor to disable these very resource intensive materials?

Cheers!
