Question by dyankov · Dec 04, 2013 at 06:30 PM · collisionmayaground

How to approximate this surface with primitives?

Hello!

I'm in the first stages of modeling the environment for my game and I'm making the env. colliders in Maya right now. My plan is block everything out with boxes and in Unity apply a Box Collider to each box. From what I have read that seems to be the most efficient way.

However, here is where I'm at:

(Gray = visible geometry, Green = colliders) I have those cylindrical stairs in the middle of the room and I can't decide how to cover it with boxes exactly. There are no cylindrical colliders in Unity and I know that mesh colliders are expensive.

What would you advise?

I would advice you to model a collision mesh, with simpler geometry, for example remove the inner dip's steps and make them into a ramp.

Mesh colliders are more expensive than box colliders for sure, but then again.

One, simplified mesh collider vs dozens of boxes?
