How can i create eye patches as accessories?

1. Create the graphic for it in your program of choice - you'll need to download the skin map in order to create it in the right area.
2. Grab the texture for one of the face paints in the base game.
3. Import your new graphic as the texture and you're done.

My advice would to be to read through some of the tutorials on this site and try little stuff like eyeliner and lipstick before attempting more complex like this if you've never done CC before.

For texture layers you can use Medibang, as I really like the brushes there compared to photoshop.

For the other images (normal, specular and shadow), I recommend Gimp. You'll have to find the dds and the normal map plugins for it first so that you can make the other three maps.
I hope this helps!

well i downloaded the skin map,exported the texture of one face paint in S4S, created the graphic of the eye patches in Gimp and now what extension do i export it (.fli, .flc , .dds, .psd etc) ?

how can i make the texture layers in medibang?

i am a little confused now
