I finally made my own contact. This contact has 2 versions, one is realistic, another is fantastic. I used HQ textures for the contacts and lashes.
The realistic version has 4 chanels for recolor: main color of the eyeball/ color of the wavy lines around the pupil/ color of dots around the pupil/ color of highlight and the white part.
The fantasy version also has 4 chanels for recolor: 3 background colors of the eyeball/ highlight + white part + wavy lines around the pupil.
The following pictures are taken when aWT's HQ mod 4096 is used (textures look very clear with the mod used):
The following pictures are taken without aWT's HQ mod (some details are lost):
Sorry for the late update here. I've been busy moving these days, and I have no access to the internet in my new house. Moreover, my laptop broke down......I did not even know many of you have already visited my Chinese blog. It seems that some of you have trouble using the eye lashes in this set without the HQ mod. Sorry for the problem caused by the HQ texture. I'm considering making another version.
