So when I discovered this I thought it was the Silly Bug that Kent talks about. But I tried the fix four or five times, but to no avail. So I went digging and when I look at my mesh in edit view, the normals seem fine. (I also did a recalculate normals. just in case) But in sculpt mode with multires on there is a line in the eyelid with bad normals. I lifted up the eyelid in edit view and the base retopologized mesh doesn't seem to have any bad normals. When I tried the shapekey (to close the eyes) this gave some rather funky effect. Is this a shrinkwrap artifact? Any suggestions? Print screens
That looks like the faces are folded onto themselves. Like when you take a sock and flip it inside out. Faces that should be in the back come up to the front as they intersect and it all makes a mess. Usually going over the messed up part with the smooth brush does the trick to un-mess the mess. Try it out and see if it helps.
Also, using the 'Front Faces Only' Option in the Brush Setting might help in those cases were Faces Are close together and/or overlapping.
Especially the Inflate and Smooth Brush are your friends here.
You might try doing this on the Base Mesh (or Move Vertices manually in Edit Mode), when the Faces are not yet overlapping, but only close together.
I tried these different things without any results. I went back in several versions of my incremental saves and it kept on happening. So I went back to just before I applied my shrinkwrap and fixed the mesh problems there. And now I'm fine, Thank God for incremental saves and keeping a version per each lesson. I tried the shape key after reshaping the mesh and it works fine. Thank you for your suggestions.
