Thats odd... when I save as .tga, I can safely preserve the alpha channel. I have Photoshop 5.5.... I don't think this is exactly the problem.

As a test.... open up a stock unit card and look at that. You will need to extract the PAK files to get at them..or if you don't want to ...drop me a PM and I will send you a stock one.

Look at that file in PSP and find the alpha channel. It will be there....and that will make sure you aer looking at the right thing. Then try saving the file as a tga. There should be some save options there when you choose to 'save a copy' ... look under the bit where you type in the name of the file when you save a copy...I think it defaults to exclude alpha...

If the file works OK...job done. If it doesn't...then you have a PSP problem!
