create a collider onto an fbx

Hello, I recently started using unity about a month ago and I am trying to make a simple game which includes a maya fbx file. In the game, I want to somehow make a collision detection with the fbx file and the camera. I tried using a mesh collider, but I was unable to find a mesh shape that would fit perfectly onto the fbx. Therefore i am wondering, Is it possible to have a collider that fits perfectly onto any shape?

Do you know how mesh colliders work? Your .fbx file includes all the data you need for this- just tick the ‘generate colliders’ box in the .fbx importer window, and it’ll even do it for you! A mesh collider works just like a mesh filter- you just drag the mesh you want onto the slot in the inspector.
