How do I put on a manual collider onto a 3D modeled asset?

I modeled a chest in Maya for a survival game that i’m making in unity. I’ve been using unity for about 8 months now, but still haven’t figured out how to do this type of collider, but for this project It’s sort of a necessity.

This is the chest, I have a basic box collider on it, but I want to be able to put things in and out, or even get into it without just floating above the open space on the box collider.


You’ll need multiple child game objects each with a collider that covers a side of the chest. I’m surprised that a convex mesh collider doesn’t work though.
