How can I make a ball bouncing more consistent?

[Adamiomn]

Hi there!

I have a ball that falls down from a starting position. I save the initial transform in a variable. It then hits a few angled planks, bouncing and/or rolling off of them. When the ball reaches the ground, I reset its transform and reset the linear and angular velocity. However, the way the ball bounces/rolls is fairly inconsistent. Sometimes it takes the same path 10-20 times but sometimes it seems to retain more or less momentum and ruins the determinism.
Is there a way of making this more consistent? Did I forget to reset something else?

Thanks in advance for any help

I think this is a limitation of the physics engine. UE5 doesn’t have determinism. “Enable Enhanced Determinism” in project settings could help though.

Thanks! I’ll try that!
