Physics collides with character

I am using the first person template to create an architectural walkthrough. My character appears to be too big to fit through some openings and can’t pass through some smaller doorways. Where do I set the size of the physics actor on the character? Also, is there a way to delete the character with a gun and just have a character walkthrough without any model elements for the character, but still have it lock to the floor. I don’t want to be able to fly all around the model. Just walk around.

To adjust the size of your characters collision, modify the height & radius values in your game characters capsule component.
This can be done in C++ or Blueprint.
To remove the meshes, you will need to modify your game characters .cpp file to remove the first person & third person meshes.

Though you may not need too do any of that, as I thought there was an architectural specific character in there already.
