Hi Simon,<br>
<br>
I’m currently working over this topic - but it is not a trivial one,
we have to be very careful with how we manages those custom normals…
You can have a look at my current working doc,

:)<br>
<br>
Best regards,<br>

<div style="">I've made a python script to edit vertex normals. <a

<div style="">It lets the user assign some faces to a group. The
normals connected to a group of faces are then smoothed
individually.</div>

<div style="">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 <a moz-do-not-send="true"

<div style="">The script has some problems that make its use
destroy workflow:</div>
<div style="">-Every time the user enters edit mode the edited
normals are lost.<br>
</div>
<div style="">-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.</div>

<div style="">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.</div>
