Butter fingers,
Thanks for the heads up.
I had to look at the pic to remember which glass door I had posted...
The door I made the texture for was not glass so my best advice for the new people would be to copy a door and rename it and then assign the texture and change the number of the material index in the new door's .fpe file.
The reasoning behind that is if you change one of the existing doors' material index number when you actuall go to use the door as it was made you will be shooting at the door but it will still react like glass instead of wood or whatever the original door was made out of.
Another idea might be if you make the door destructible to use the glasssmash scripts in the destroy folder.The downside of this is the whole door will be destroyed not just the part that seems to be glass.
