I would like to be able to tell the exporter how to group certain parts of the source images.
The reason is to achieve better (lossy) PNG compression, since I'm running a lossy PNG optimizer on my textures.
Example scenario:
I have a avatar with a yellow skin color, red shirt and hat and green pants and shoes and gloves.
Ideally, I'd love to tell the exporter to create 3 different atlases, one for the items with the skin color, one for the red clothes, and one for the green clothes, instead of just randomly throwing all colors into one or two atlasses ( This is just an example, but hopefully the idea comes across).
Sooo, is there anyway to specify how to group items into atlasses?
Thanks!
