Follow up from "shading problems": avoiding Mirror + Shrinkwrap to merge each other's vertexes


Right now, I’m currently doing a stylized version of a character from Cookie Run (Strawberry Crepe Cookie) and I want to make a clipping-like modifier combo in which the pupils disappear as they get off the sclera.

Well, I’m currently tweaking anything because when I place the pupils in their “rest position”, they magically merge each other, and I have no idea what to change in other for them to “wash away” instead of merging.

If I understand your question right which is to avoid geometry from merging just disable clipping and merge in the modifiers but I can see you have already done that.

As for a clipping effect to make the pupils merge where they meet, why can’t you use the clipping with mirror modifier? Do you really need to merge the geometry and couldn’t this be done in a shader with simple masking?
