I'm doing an animation in Blender where a bunch of cans are falling in an enclosed space. I give the cans a rigid body and enable collision on the bottom plane that they land on.
What I'm trying to do is make it so after the cans land on the platform there's a trapdoor that animates open causing them to fall through the floor. When I tried to do this by detaching part of the plane and animating it the cans don't fall through.
Can you guys help me figure out how to achieve this effect? Thanks. I feel like i'm missing a key element in these physics.
