problems with overlays

[keir]

im having a problem with overlays, some of them have black around them or to the side or on top or whatever.
Mainly with doors, am I doing something wrong or are some of the textures suppose to me like this?

Doors aren't used as an overlay.
make a brush 56x112 and then apply the door texture you want. Do a search in the texture window for dev_measuredoor01 and you'll find a texture to help you out.
Also, not all textures are meant to be used as an overlay so if it has black around it when you place in on your map then that probably isn't one of them. Usually overlay or decal textures have a grey background in the texture window.
