Re: How to edit winmask files?
it looks like single-channel Truevision TARGA file (TGA texture). You can rename this file from .mask to .tga and open it in any image editor. I don't know whether the window glass object is explicitly UV-mapped onto texture or not, but in general you can edit this texture in image editor to match your needs.
