Bugfix:
Fix for "Use pupmenu menu to select align orientation. Faster workflow than always having to change the current transform orientation beforehand."
memory corruption... (theeth ? )
Bring back multivert normal average for the normal manipulator/orientation.
When selecting more than three vertice, the averaged normal of all selected is used to get orientation Z-axis.
NOTE: This is only applicable when NO faces are selected, otherwise it uses the averaged normal of the faces (excluding vertice that aren't part of a face). This is not new behavior
CHANGES FROM 2.45: Selecting 2 or 3 vertice doesn't use normal averaging but uses virtual edge and face orientations instead.
Merge Normal orientation calculations with Custom Orientations, to make it work the same all accross the table:
- One or more faces: use average face normal (first edge of faces define tangent)
- One edge: use edge itself as normal (vertex normals define tangent)
- One vertex: use vertex normal (tangent is perpendicular to normal and z-axis)
- Two vertices => edge orientation
- Two vertices => face orientation
*I tested quite a bit but please report any bugs this might have caused.*
