How to make FPS character move inside a building model?

I am trying to do something as simple as importing a FBX model of a building and making my FPS character to walk inside it.

I have no problem with the FPS character nor with importing the model. What I am having trouble with is to actually making the character walk inside the model.

I have tried applying a box collider and mesh collider with no effect. I have also tried making sure the character is inside the model and above it. Nevertheless, everytime the character falls through the building. It only stops if I have a plane under the building.

What am I doing wrong or simply not doing? Maybe some FBX import setting I need to set?

Thanks.

We worked it out :slight_smile:

@nuno needed to add a mesh collider and make sure that the mesh was actually selected in the mesh on the collider.

The mesh collider also needed to be added to a separate game object that was scaled, this is due to some factor about the import that I don’t understand.
