[SOLVED] Wallmask doesn't work

[SimSamBol]

please, help me with this: my window wallmask isn't working, the wall in which i put it doesn't appear with the hole. what's wrong?

Did you save wallmask in .png format? (From description, this sounds most likely)
did you do 'build' and use DXT3 format?
Are you sure you have the 'right' wall mask -- there are often all those diagonal ones in the straight version. It can be very confusing.
Did you commit & save after pulling in the wallmask?

oh, my problem was when importing, i imported the image by clicking in the buttom 'import". that's it, thanks!
