Adding physics to imported objects


I tried to import a football I made in blender to Unreal Engine 4, and make it act like a real football with physics. But I am unable to check “Simulate Physics”. Does anyone know why I can’t, and how I can fix it?

Hey ,

Does your Mesh have collision on it? Without collision, you won’t be able to simulate physics. Put some collision on it via Mesh Editor > Collision and save. Then Simulate Physics checkbox will be enabled.
