OnCollisionEnter not being called reliably

Unity Engine
1

I setup an object with a collider and a rigidbody. When it hits something it’ll bounce off of it like you expect, but only sometimes will it do the OnCollisionEnter callback.

If it bounces, it obviously did a proper collision. So any idea why the callback is not happening 100% of the time?

Best guess atm: Your fixed timestep might be too high.

That wouldn’t be logical. If the objects were passing through each other, sure. But I’m just talking about reporting the collision that actually took place. You can tell because it bounces off visually.
