4 alpha channels

[CapMorgan]

Hi all, i have a problem with a "cristal box". No matter how i map the textures i always get this error in one of the four faces.
As you can see (or not ), the inside is not visible thru the glass.
Any clue?
thanx.

Try selecting all the glass panels and then cut (ctrl-x) and paste (ctrl-v) them back in that should sort it out.
