I am making a script for a sports game(FIFA 14) and i need to import some objects that actually contain information about each spectator’s seat (position, seat rotation, color etc). The positions are stored like certices and my purpose is to visualize these vertices somehow.
What i’ve done now is to create a mesh with all these vertices, and of course i have no faces.
What i want now is to find a way to apply that seat rotation to the vertex normal in order to be able to see it in the viewport through the normals.
The problem is that i’ve never been able to change any face’s normal permanently. Blender keeps recalculating them.
How can i change the mesh’s normals and protect them from recalculation?
