Problem with normals...what else? When I try to remesh, I see this


  QuadriFlow: The mesh needs to be manifold and have face normals that point in a consistent direction.


It won't let me remesh. Shift + N won't work and in Face Orientation all I see is red (as per pic). What can I do?

Thanks
the same thing happened to me, what worked for me was to first voxel remesh it at something like .0001 then all of the normals were fixed and I clicked quad and everything worked fine.
