I'm doing retopology with subdivision surface and shrinkwrap modifiers. In yesterday's project, the viewport behaved like this:
Today it looks like this:
The problem is that the "control points" (actually just the pre-modifier mesh) gets buried inside the mesh and I can't see what I'm doing. In the other file the edges were curved with the subdivisions, making sure they were always visible.
The subdivision surface modifier settings are identical for the two files, so the issue must be elsewhere.
