What is the best collider to use for a simple (1 quad) plane?

Questions & Answers

Sorry if it’s a daft question. I keep reading that mesh colliders are inefficient, but I’m not sure if that’s just because most meshes are more complex than the primitives.

If I have a really simple mesh - just 1 quad (i.e. 2 tris) - is it more efficient for me to use a mesh collider, or a box collider with 0 height? (I only need to detect collisions from one side)

Thanks in advance :slight_smile:

It does depends entirely on what you will use it for.

If it is some sort of terrain/scenery, use a mesh collider and click the ‘static’ button in inspector. If you wish to manipulate it (movement etc) then a box collider will do. Of course (given the above comments) you would need a ‘thick’ collider but this is perfectly fine if you intend to use only 1 side of the quad.
