Paa and pac formats

[Hara Kiri]

what is difference between them?

I think paa can have an alpha channel and pac cannot, but other than that I'm not sure.

I can't describe it correctly, but the .pac will be "visible" through the dust, smoke, and the transparent textures. The .paa will work as usual.

The only real difference between the two is that the PAC format seems to have a 1 bit alpha channel, and PAAs have an 8 bit alpha channel. PACs are useful for making things like bushes because they only have either fully transparent or fully opaque parts, eliminating graphical errors that occur when using PAAs.

Thanks for that information http://forums.bistudio.com/oldsmileys/smile_o.gif

PAA format also creates the 'blotchy' look that so many people complain about on OFP textures. PAC format is, IMHO, more suitable for opaque textures where complex alpha channels aren't needed.
