Rigidbody gameobject falls through plane
I have a rigidbody gameobject that has a box collider. The object is supposed to fly straight over the plane but when I run the scene the object just falls through the plane. The plane has a mesh collider with convex turned on but the object still falls through the plane. Any ideas why this is happpening?
I know this seems like a simple question but I'm new to unity so bare with me.
What layers are the objects on? If they're on layers that aren't set to collide with each other, they'll pass right through each other. You can check what layers collide with what under Edit -> Project Settings -> Physics, and seeing what checkboxes are ticked in the collision matrix.
Don't use mesh collider on a plane. It's just too costly first of all. Use box collider. Make sure if isTrigger is not turned on. Add rigid body.
