some pictures which I deal with recently must be export png format file with alpha channel.
as i know photoshop 5.5 can export png file with alpha channel,
but I don't wanna use it,because photoshop 5.5 is not convenient.
I use photoshop cs now,but I can't export png flie with alpha channel.
who knows any solutions or plugin can fix this prob.

Hi, I didn't think png supported Alpha Channels but they do support transparency. If you want alpha channels tga are a good way to go.

but game engine support png file with alpha.
so all the texture must be png format.
but i don't like photoshop 5.5.:sad:

I dont think PNG is 5.5 in Photoshop doesnt have the ability to write out an alpha...thats pretty old technology... PNGs support transparency, so ya shouldnt need a separate channel.

the version is higher than 5.5's photoshop can't save the png file with alpha channel.
I had tested.
I don't think the png file that high version photoshop saved support transparency.
maybe some plugins can do that.
