Do invisible open edges matter with weapons? You can't see the the open edges their inside the weapon.

I think all open edges matter, no mater where they are, unless they are in render-only materials.

Hmmmm...I just compiled it anyway since i wasn't getting answers and it didn't come up with any errors. maybe they don't matter or i'm just really lucky. :)

I don't know much about weapons, but if they are anything like scenery, they have a regular model and a collision model. Which did you compile?

I would have said that weapons never use collision, but then I remembered that you can shoot them on the ground and they spin/ fly, and also when you're holding them they can be shot and you take damage, so they must use a collision model of some sort.

edge errors only matter for things that have collision.. BSPs always have collision built right in.. but with other objects, such as weapons, scenery, vehicles. the collision is a seperate tag. The gbxmodel can have what ever deformitys you want, but the collision_model cant, and will respond the same as building a BSP.
