ball falls through maze (mesh collider) Why?

Unity Engine
1

I have a maze model (with a mesh collider attached) into which i have placed a ball object (with a sphere collider and rigidbody attached).

The problem is the ball just falls through the maze, why is it that this happens?

All help is much appreciated! :slight_smile:

Can you pass me the project？

I help you see where wrong.happens

i’d rather not send across my project… are there any common reasons why that happens that you could tell me and i can try?

ball is moving too fast.

try:

  1. lowering time between physics updates
  2. setting the ball to dynamic collision detection
  3. put box colliders around the bits where the ball is likely to fall through
  4. use convex mesh colliders where possible

Ok I am having the same issue except it doesn’t happen all the time it is only when I get the balls to bounce really fast. I did everything except lower the time between physics updates… HOW do you do that?
