[Bf-gamedev] vertex normals editing

[Simon Broggi]

Hello everyone,

I've made a python script to edit vertex normals.
https://github.com/simonbroggi/Blender-Smoothgroups

It lets the user assign some faces to a group. The normals connected to a
group of faces are then smoothed individually.

The simplest application of this script is to create a beveled cube with
correct vertex normals and a minimum amount of polygons. In this image, the
cube on the right is makes use of the script

The script has some problems that make its use destroy workflow:
-Every time the user enters edit mode the edited normals are lost.
-Modifiers recalculate the normals. It would be great to use the script in
combination with the edge split modifier, as this is another convenient
method to edit normals. Unfortunately the modifier ignores the normals and
recalculates everything.

These problems could be solved by implementing something similar in the c
code of blender. It would probably make sense to implement it as a
modifier. This would be a valuable tool for game artists.

Greetings, Simon
