I created a few props with propper. In the propper_model/physics mesh I put in the same value I had in the propper_model/name field. When I compile these to props and put them in a map using physics_static the compiled map's resulting collsion models are large boxes that won't let you enter the models and stretch to the outskirts of the farthest point to form a box, making you appear to walk far above them. How can I make the physical collision model match the visual model exactly for these? I am new to models, thanks.
