Getting model import settings for mesh asset created from Unity

So, I have a ton of mesh assets that I need to use both for colliders and mesh renderers. When I assign them to a collider, there's a quite heavy Mesh.Bake Physx CollisionData step that happens when Instantiating them. However, in model import, there's a Generate Colliders step that would probably do this beforehand.

The problem is, I save my meshes from Unity as .asset files, which don't have those settings. Is there a way to get those settings without having to create objs for everything? This would save me a whole lot of time. Thanks!

 

Nevermind, I converted my meshes to .obj files and checked the add collider setting, the spikes are still there. I will try to make prefabs with colliders and check the prebake mesh colliders, see if that helps.
