Are you able to put some of the outfits into a big 1024*1024 split up, example
hair.png (1024x1024)
- Would contain all the hair for the outfits you've done above.
shirt.png (1024x1024)
- Would contain all the shirts you done etc.
Then upload that as a zip for me
So in all there should be
-hats.png
-shirts.png
-pants.png
-shoes.png
-capes.png
