i’ve tried your suggestion but it didn’t worked. maybe i need to explain my problem a bit better. i want to make a cube fall onto an object that rotates. for example an cube that is falling onto an rotating cube. i use the solver object and gravity to make the object fall, i also added the rigid body dynamics tag. When the cube has fallen onto the cube i want the both cubes to rotate. i keep getting the problem that the cubes falls and dont rotate. the other cubes spins but the cube with gravity does nothing. hopes this clears thing up a bit.
