A couple months ago I dabbled with getting a projectile to pass through a wall and leave a mark, and it was never totally successful. I figured I'd try this again but with only glass, that it should be easier somehow, yet it isn't. Right under where the game does the trace in g_runrocket or whatever, I added: if ( tr.surfaceFlags & SURF_METAL ) { G_AddEvent( ent, EV_MISSILE_MISS_GLASS, DirToByte( tr.plane.normal ) ); G_Printf( "work dammmit \n"); } this is right above the part: if ( tr.startsolid || tr.allsolid ) { The idea is if the surface the trace touched is metal (yes surf_metal for now because of problems with adding new surfs), then add the event mostly for the CG effects to occur. In game this does nothing on either a brush or a plane with the glass texture. So back to the question: how would you get the game to detect the type of surface the projectile touched, and how would you tell it to place a mark on that surface while allowing the projectile to continue through it?

It just has to be surface flag specific and as it is it's like it completely disregards the surface type check. I wasn't sure about how to approach this one since my past attempts failed. The other problem is that the surfaces I'm using are planes the game just ignores any type of collision with planes.
