Just created a mansion in Blender which is going to be included in my FPS game, so proud of it, didn’t know that i could do something like this. But the problem is when i exported the model to Unity and put an FPS Controller inside it and started the game, it fell through the mansion’s floor. I added a mesh renderer and box collider to the model, but it didnt help.

Try adding a mesh collider instead of a box collider. IF you add a box collider it will only create a cube shaped collider.
