Hi all, I’ve been going in circles on this issue of finding the best compression format for Sprites on Droid.
What I’m I trying to do it is compression formats that have a low file size but still keep image a decent quality.
I’ve grouped my sprites on atlases based on there appearance ie: alpha, semi transparent and flat colour/ gradient.
ETC2 8 bit works the best and keeps semi transparent pixel quality but the file size is huge.
ETC2 4 bit with 1 bit alpha has great compression on the file size but the image quality isn’t great.
ASTC is great but doesn’t like semi transparency much plus I’m not sure on what devices support this.
DXT5 is awesome but again I’m not sure what devices are supported.
I’m trying a mix of ETC’s but I guess someone has come across this and hopefully has a optimal answer.
Any help is appreciated
