This is the core code for it, tools (datatransfer and modifier) will come in next commits).
RNA api is already there, though.
See the code for details, but basically, we define, for each 'smooth fan'
(which is a set of adjacent loops around a same vertex that are smooth, i.e. have a single same normal),
a 'loop normal space' (or lnor space), using auto-computed normal and relevant edges, and store
custom normal as two angular factors inside that space. This allows to have custom normals
'following' deformations of the geometry, and to only save two shorts per loop in new clnor CDLayer.
Normal manipulation (editing, mixing, interpolating, etc.) shall always happen with plain 3D vectors normals,
and be converted back into storage format at the end.
Clnor computation has also been threaded (at least for Mesh case, not for BMesh), since the process can
be rather heavy with high poly meshes.
Also, bumping subversion, and fix mess in 2.70 versioning code.
* Same issue as T42760 was also reproducible in some cases in 3DView.
* You got an error message about missing RNA prop in some drop-called operators.
* You could not drop a movie file in nodes, (some cases of) 3DView, nor ImageEditor.
Add simple uvs now does a cube unwrap and pack operation. Result is not
optimal by far but it should not result in crashes and it will be quite
usable for simple cases.
Do not generate materials/images/UVs if they are missing.
Now we spawn a panel ("Missing Data") with operators to generate the missing data and
pop a warning if user tries to paint without them.
The reason we have reverted this is that it is too easy to end up with more textures
than we wanted. It was impossible to enter texture paint without having textures added,
and code makes too many assumptions about what user may want.
Discussed during Sunday's meeting.
This might be a candidate for 2.72a but I'm not sure how other artists will take this
(and how refined and crash-free it is), better make a few iterations first.
And for interested parties...test please, don't wait until after a release to poke with such issues.
Also, add slot operator now adds a new unconnected image node in cycles. Only
used in the "Missing Data" panel. This should be a separate commit but I am squashing it into the same commit because
it relies too much on changes done here and can be reverted easily if complainstorm occurs again.
Another Evil Typo (r) one, you could add much more than the 8 allowed VCol layers!
Note: added some (warning-only) checks in mesh validate functions, but we still have a big issue with new cdlayer merge function, which could generate more than 8 layers of UVs or VCol... Don't know yet how to handle this situation. :(
flush the selection on entering editmode instead (since the selection mode can be changed with another mesh).
is other tools leave the selection incorrectly flushed, those will need to be fixed so transform works as expected.
- give feedback on how many mirror verts succeed/fail (for select mirror, shape key mirror, weight mirror)
... when a mirror failed it was confusing and not obvious what was going on.
- slight change to select mirror, now center vertices will remain selected.
- speedup to EDBM_verts_mirror_cache_begin, cache customdata layer offset.
note: that this intentionally removes check to exit vpaint mode when a vertex color layer is removed,
since being in vertex-paint mode without a vertex color layer is supported.
also minor change to drawing camera limits while picking from previous commit.
Adding new image texture to Meshes didn't initialize UVs to 0-1 default.
This makes initial display of textures on meshes not work.
This fixes my favorite demo case: Open Blender, drop image from desktop on cube.
reported as [#29376] BMESH_TODO: remove tessface CD_ORIGINDEX layer
for a single mesh there could be 3 origindex mappings stored, one on the polygons and 2 on the tessfaces.
(CD_POLYINDEX and CD_ORIGINDEX).
as Andrew suggests, now tessfaces (which are really a cache of polygons), using origindex to point to polygons on
the same derived mesh, and polygons only store the original index values.
fix pose-group-sort and pose-group-moving being disabled for pinned poses.
also fix for own missing NULL check for pose mask clear which would crash when run without an active object
updating data was only being done on the active object but sticly was being calculated for the selection.
split this into 2 operators, one that works on the selection and another that operates on the active object - so we can have a button in the mesh panels that calculates sticky.
also note that there was no way to calculate sticky from the UI - perhaps this feature should die a quiet death?
anyway - it works better then it used to for now.
currently can remove sticky/mask/skin vertex layers.
regarding the skin layer - while adding and removing the modifier normally works fine, its not 100% reliable since the mesh may be linked into another scene, or be a linked duplicate and the object with the modifier deleted.
