Mesh Extraction and normals

[system]

Hello, I’ve a problem with extrations from my mesh, e.g:

The upper one is the extraction, the lower part of the image is when I turn Dynamesh on. Im basically trying to get better geometry by later zremeshing it, but after I dynamesh it the normals seem to go all bat**** crazy.
I’ve tried to fiddle with the Display Properties menu but to no success, I tried both flipping the normals and turning on and off the double sided option. None if it seems to work. Is there a way for this to be avoided or fixed?

Dynamesh can have problems with very thin meshes and will create multiple holes.
If you want to lower the resolution to avoid sending high res meshes to Zremesher better to use decimation master. But Zremesher should not have problems unless it is several hundred of thousands verts. If you want simply to refine the shape the current geo should be ok.

Oh, ok thanks. I did the dumb-fix by inflating and smoothing out then dynameshing and it seemed to work D:
