How to make soft-body sphere stay inside concave object? So, I have a soft body sphere inside a 'maze', (this is just the beginning of it) like this...

The sphere has soft body settings of:



The maze had settings of:


However, as soon as I played the animation, the sphere squished and jumped out the back part of the maze... What I wanted it to do was roll down the ledge. 

NOTE: This may be a duplicate, but I've looked up around the place and nobody has had the same problem as me (that I've seen).
The physics solver tries to minimise the work it does by making approximations. You can increase the number of steps the solver will calculate and the number of iterations attempted to improve the detail of collisions.

On the Scene tab under Rigid body settings there is "Steps per second" and "Solver iterations" 

But be wary, increasing them too much will slow the simulation time significantly.
