Setting photoshop's alpha channel bit depth
Author
I installed CS and it seems to work in CS, so I guess it's a versioning problem. Now I just need to figure out how to turn my targa into a dds...

Okay, if I flatten the image like someone suggested earlier (didn't work in 7.0, but CS it seems to works), it will let me save the alpha channel as the transparency in a DDS (for DXT5 anyway). DXT1 is still giving me a bit of trouble, but I think I can figure it out with a little more effort. And anyway I can convert from the DXT5 to DXT1 easily enough.
So thanks everyone for your help and patience :)

There was a problem with Photoshop 7 and alpha in TGA files. Adobe changed it to save transparency information as the alpha channel in TGA files instead of using the actual alpha channel. They fixed it in 7.0.1, but you can download the fixed TGA plugin from here:

My issue isn't just with TGAs. It seems they introduced a new filter in CS called something like "save alpha channels" in the save file dialog. That's what I need to have checked for this to work.
