I have geometry being created through geometry nodes and I am am trying to flip the normals on this duplicate geometry. However, it appears that normals are a read only attribute in the geometry nodes. Any ideas on how I can flip normals through geometry nodes?
It is possible to flip normals for any single face. You just have to do several steps:
- Detach selected face from mesh.
- Put this face into convex hull.
- Delete from convex hull all faces with normals orientation equal to normals orientation of the original face.
I already applied this solution in my answer here: Is extrude possible in Geometry Nodes?
