Mesh colliders

Unity Engine
1

Hi there,

I would like to find out about the amount of mesh colliders Unity can handle. For example, when I make a building in Sketchup, and explode everything completely, and export to FBX > Unity, then Unity pick it up as one mesh, and I only add one mesh collider. Is that correct to say then for each building there is one collider, and not per triangle of mesh?

Cheers

Yes, that is correct (though that one collider, of course, contains every triangle in the mesh).

I don’t think there’s any theoretical limit to the number of meshcolliders you can have in a scene, any more than there’s a limit to any other kind of component.

Thanks, I was just curious, as I know there is a limit to Capsule colliders. (cannot find the info now though)
Does adding a mesh collider to an object have an impact on the framerates?

Something I experienced was that every additional mesh collider increases the loading time at the beginning due to initialization or something like that.
