I made a clean retopo of a highpoly sculpt and tried to project all the details in the subtool palette. Everything worked out quite nicely, but in some areas the model kind of exploded. See picture.
I have checked my retopo for failures, but couldn’t find any. It’s all quads, no lose verts, no non manifold edges etc.
Here’s is a wire of the retopop and a pic of the strange issue
