I have made my own model in 3ds max and imported it so I can use it in Hammer. My problem is that when I run my map the model don?t shows up. If I change to prop_dynamic my model shows up, but I need to use prop_physics becouse I want my model to fly and explode. I tried to search the forum but i could only find post concerning the in-game models and not user-made. I have a screenshot of my model when it is a prop_dynamic, as u can see the shots went right through it. 
How can I make my model use prop_physics?
