So, here are some experimental iris underlay textures.
DeepDiveEyes are used in the preview model.
To use, put the texture in Iris Underlay like in the preview!!
O, don't forget to turn pupil transparency all the way down!
Enjoy~☆ᕙ( ˙-˙ )ᕗ
Update: I now added a sample chara card using one of the overlays ;)
