Wire render normals were exactly opposite to the normals for solid faces.
This caused displacement to work inverse too. Flipped them.
(Note; for shading normals are corrected to point towards viewer)
Reading DXF curves can result in corrupted edges (with 2 identical
vertex indices). Probably thats OK for autocad or so.. but it made
Blender crash on entering editmode.
The issue was that particle emittors were still transformed by the object
matrix itself. That was solved in the previous commit, but there was
still an error in correctly evaluating dependencies for the object...
Current commit uses depsgraph to recalculate all objects that influence
the emittor.
The depsgraph code doesn't like particles much (because it uses baking).
Current construct is still weak, is on the list to solve nice.
"Full OSA" render used wrong subsample pattern for accumulating passrender
info. Was only noticable for the 'normal' pass, for example on raytraced
images. Image looked as if it had a wireframe render.
Raymirror didn't use proper texture-space 'osa vectors' for sky texture,
causing extremely blurred reflections of sky.
Error was actually a mixup of arguments for sky render...
When using CTRL+L for materials, you can end up with non-existing material
indices in faces. The drawing code then was still happily drawing the old
situation (or something random, its a static array).
This commit checks the maximum amount of materials on an object, and draws
the last available material for a non-existing index. It uses an ugly
global yes, but this code is bad anyway. :)
Dynamic particles sometimes didn't properly use global coordinates.
Meaning they were transformed by an Object, for example when it has
animation constraints.
Error caused by attempt to get duplicators to work for particles. Will
need re-evaluation this.. for now restored old functionality, with
exception of dupli-groups.
Particle strands with a width set (like 10 pixels), and with extreme
bending of strands (like a very course subdivision), could create non-flat
quads. For speed reasons, the quad-to-triangle splitting was turned off
for hair, but in this case that should be done nevertheless.
Solves another Dandruff issue for furry bunnies!
oblivious of each other, so setting/clearing the face edit mode select status
did not set/clear the corresponding vertex select statuses. This patch makes
a change of any select status recalculate the selection state of all edges an
faces. One unresolved issue is what effect this should have on the recent
edge mesh's stored selection. Currently changing the selection state will
delete store selection info, but it may be desirable to emulate the stored
selection (but I need to discuss how this should work in more depth with
Geoffrey Bantle).
As an added bonus (while I was messing with this), I added a "sel" attribute
to edges so they are the same as faces and vert.
meshes, and actually fix the bug that caused the crash. The fluidsim result
doesn't preserve a mapping to the original mesh, so it shouldn't be displayed
in face select mode.
Made obj_export use getMeshFromObject
obj_export now copies images from mtex as well as texface when copy images enabled.
obj_export tested to work with exporting fluidsim animations (somebody reported it was broken, must have been fixed at some point?)
variable blah at a higher scope is already defined...
(one of these was introduced by me when I moved a variable declaration
to the top of the function.)

at the moment it only has meshWeight2Dict and dict2MeshWeight
These allow you to deal with vertex weights as a list of dicts which makes scrips short and easy to understand.
(kh_python, perhaps dict access to the python verts could replace this )
Used the above util functions to update mesh_cleanup.
Copied from the source
'Material Clean', 'Remove unused materials.'
'VGroups'
'Group Clean', 'Remove vertex groups that have no verts using them.'
'Weight Clean', 'Remove zero weighted verts from groups (limit is zero threshold).'
'Weight Normalize', 'Make the sum total of vertex weights accross vgroups 1.0 for each vertex.'
Normalizing lets you see how much % of the vertex a bone owns just by looking at 1 of the bone weights.
Would be nice to have this functionality in Blender but theres not much room for new buttons in teh vgroup and material area :/
Outliner, Group view, operation menu "unlink group" also set the group user
counter to zero, which it should not do.
Note; the definition of this command is to make sure no users exist of this
group, but the group itself can still be there with objects.
Since the text-object remake, it was not possible anymore to 'cut out'
text from, say, a box made by a polycurve, by converting text to curve
and then joining - only the first character would be cut out.
This is because of the filling groups (nu/dl->charidx)
I introduced for getting the vast speedup and the possibility
of overlapping characters.
The new convert menu option now assigns filling group 0 to all of
the nurbs generated.
Maybe filling groups should be exposed in the UI in general for curves -
there are various occasions where they are useful.
(Hint to the UI mafia! ;)
Stored selections now get saved to mesh library blocks as direct data.
The idea that stored selections are 'erased' when leaving editmode and
switching objects is pretty mysterious for the user. Note that currently
the mselect array in a mesh is not written to file. Not sure whether
to change this or not.
(Now always work on copied data- Blender.Mesh could do with a copy function)
Now triangulate works without "Apply Modifiers" enabled.
Much thanks to Gianluca Faletti for helping me track down the problem.
