Hello, I noticed that the mesh simplification gave strange results with a rather simple, single-sided, semi-spherical mesh.
I can't really explain it yet, but as you can see, I end up with ghost triangles, the outer shell is good though with back face culling, but without culling the ghost triangles start to show in my viewer...
The flipped triangles start showing in the first collapse round already, they appear very thin and tiny at first, I guess that they start growing as more iterations are performed
