Rigidbody falls through Box Collider

Unity Engine
1

Hey all,

I have a table with a box collider, and it’s not thin, with a book (with a Rigidbody) on top of the table. When I press play, the book falls right through the table.

I even placed the table on top of some terrain and the book falls through the terrain.

Any ideas on how to fix this?

Thanks in advanced.

Does the book have a collider too?

I’m sorry for responding so late, yes it does have a rigidbody and collider.

you don’t have ‘Is Trigger’ checked in the book’s collider, do you?
