Hello.
DDS (BC7) is a common texture compression format used by lots of moderns games.
And now with ffnx 1.50+ you can use this format with FF7 instead of png.
It's having lots of adventages:
-It's realy fast for loading and all the job is done with graphic card and not cpu
-It's take less memory (about 25/30% of png) so no more texture corruption problems
-It's visualy loseless
-It's compressing well so the iro or 7z share of the mod will be realy lighter (for my full pack 7z png is 6go and 7z dds is 2.3go)
To convert from png to dds i made this simple gui witch is self explainatory, but if you need help, just ask ^^
It can also convert a classic iro file mod to iro dds file.
It Can also convert dds to png (as dds is a lossy codec, don't do dds > png > dds ... you'll have quality loss after some time)
