Hair can be kept dry(!), but this is a priority type. So in order for the slime to be on the head, it is necessary to strengthen, for example: "(Wet hair:1.5)"

0.4-0.5 The slime will look more like clothes.
0.8-1.0 The poses will become more uniform.

The slime can be given color, but different colors have different texture, transparency and style.
