Hello - Does anyone know a simple way to reverse the normals on a mesh where some are backfaced but not all? cant just use the reverse sop as it inverts everything. I guess i could do some kind of nearpoint look up in vex and use the dot product to see if it's in a different direction but it doesnt feel like it will work exactly?
Anyone had this issue before?
Reversing normals, but selectively

hummm musnt be manifold as polydoctor sop doent work :-(
It's a FBX export of a solidworks model which i suspect is just not cut out for this
looks like it might be a manual selection (might be able to select by normal using the delete sop)
thank you!

polydoctor manifold check only works if the meshes are are non-manifold. An entire manifold being reversed from the desired state doesn't make it non-manfold.
Try the winding number sop to determine which meshes are reversed. If I remember, a negative winding number is reversed orientation.
