So I am looking to change the normal direction from being 90° on the face to just kind of lay flat on the face. Is that possible to achieve in Blender? Or are there any addons that will help with this?

  • $\begingroup$ May I ask why you want to do that? It is just that blender calculates its normals. They are not something that can easily be modified. $\endgroup$ – Gerald Degeneve Jun 15 '18 at 1:05

If you want to modify specific normals of specific faces of a mesh, the only way I know of is the "Normal Edit" modifier.

Basically you create a vertex group, containing all the faces you want the normals changed of. Then add the Normal Edit modifier, choose Directional, select the vertex group and pick a target object. After that all normals of all faces of the selected vertex group will point in the direction of the center of the target object. If you want the normals be parallel, select Parallel Normals in the modifier.
