Short description of error
physics bounce value doesnt work unless both objects bounce
Exact steps for others to reproduce the error
open provided file and press play, the ball doesnt bounce even though it's bounce value is set to 1. select the ground plane and then in the physics tab set it's bounce to 1, now the ball does bounce.
I've checked to make sure that i'ts not just the behaviour of passive rigid bodies, and the same problem applies even if both colliding objects are active rigid bodies (one animated so it didnt move).
This makes it impossible for a ball to bounce off of a collapsible brick wall for example, as the bricks would have hardly any bounce of their own so that they can land properly.
