A few people have recently been bitten by this bug, and I blame myself for not highlighting it more in my tutorials as it can be frustrating. The bug impacts saving 32-bit TGA files in Photoshop 7.0 — alpha channel transparency doesn’t work. So if you’ve done any of my tutorials and just couldn’t get Alpha Channels to work, my bet is you’ve run into this problem. Luckily all you have to do is download the free Photoshop 7.0.1 update from Adobe’s site.
From the 7.0.1 release notes: “Photoshop now saves alpha transparency data in Targa files in the same way it did in previous versions.”
