complex blender collision efficiency

Question

I'm making a little project where you put a ball through a maze. I made a rounded corner so the ball would easily take corners. Here's the shape:

Then I shape 6 different shapes around this one so that I can later give those 6 shapes Box Colliders in Unity

Now my question: When I import this in Unity and give the 6 added shapes box Colliders it works well. BUT is there a better, more efficient way of giving a non-standard shape a complex collision?

Answer 1

Yes there is and it is called a MeshCollider. It creates the collider according to the original mesh. Link to docs.
