Note this func needs some love, but this will be for later (should never have been in shrinkwrap code!).

The issue was caused by NLA evaluation without actions not setting
id's flag as updated (as that's happening when action writes data
to the ID datablock).
Added the same flag set for the NLA evaluation as what's happening
for actions.

The issue was caused by the render engine loading edit mesh, which re-allocates
mesh array which might be referenced by other object's derived meshed.
Worst thing about this is that updating render engine happens from the end of
scene update function, after all the objects are updated and so. This is needed
so render engine gets the update objects which is correct.
The only proper way to solve the issue is to make it so viewport engine does not
leave objects in inconsistent state, meaning nobody will reference to freed data.
In order to reach this we do edit mesh loading before running objects update so
all the objects which uses that mesh will have proper references in the derived
mesh.
This also solves old creepyness which happened before when having single object
in edit mode. tweaking it will calculate derived mesh as a part of scene update,
then this derived mesh will be freed by edit mesh loading and viewport will be
creating derived mesh again.
Now render engine is expected to do nothing with meshes which are in edit mode,
but they still need to load edit data for non0meshes. It's not really easy to
do from the BKE level because needed functions are implemented in the editor.
Thanks Campbell for the review!

Own copy and paste typo in 73d157e meant that this was not in some cases,
the bounds calculated may be incorrect.

meshes with shaped keys
Same issue as revious one -- need to start OMP threads only
when there's enough data to crunch.
|
|
Issue wascaused by the famous OpenMP crap in MSVC2013,
so only way is to use openmp threading if number of BVH
nodes is high enough.
Made it 8 for now, which seems to work rather fine on my
laptop and adult dragon from sintel. But maybe it's to be
adjusted a bit more.

This allows adding a "fake" sun beam effect, simulating crepuscular rays
from light being scattered in a medium like the atmosphere or deep water.
Such effects can be created also by renderers using volumetric lighting,
but the compositor feature is a lot cheaper and is independent from 3D
rendering. This makes it ideally suited for motion graphics.
The implementation uses am optimized accumulation method for gathering
color values along a line segment. The inner buffer loop uses fixed
offset increments to avoid unnecessary multiplications and avoids
variables by using compile-time specialization (see inline comments
for further details).

Add ability to select UV layer from the layer panel.

If the active image node contributes to the final material shader
(meaning it's either directly or indirectly connected to an Output Node)
the user will receive an alert about circular dependency.
Similar to what we do for Blender internal the baking will still happen,
but the user will receive the alert which should prevent the image
saving to happen if the result was not intentional.
Core function to check for node output written by Lukas Toenne.

Rename UI_init_userdef_factory to BLO_update_defaults_userpref_blend
This closely matches BLO_update_defaults_startup_blend so makes sense for them to be together.

* paint slots from cycles only include texture image types
* tweaking with select mouse no longer confirms on release

The issue was caused by the wrong objects order for
convertblender.c. Dependency graph totally missed
handling of this situation.
Fixed now, but it's not that pretty, don't try this
at home obviously. But consider this to be good enough
for the current dependency graph.
Details are in the build_dag_object().

Yep, at last it's here!
There are a few minor issues remaining but development can go on in
master after discussion at blender institute.
For full list of features see:
http://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.72/Painting
Thanks to Sergey and Campbell for the extensive review and to the
countless artists that have given their input and reported issues during
development.

Importantly, reversed mul_serie_m3 argument order (so it matches the m4 function)
|

The "Show All" and "Show Selected" operators in the Graph Editor was taking into
account all handles on keyframes, even when some of those would be invalid and/or
set to nonsense values (e.g. for any interpolation mode other than "Bezier")
|

NULL's)

(cycles).
There were several small issues/inconsistencies if how particles' org face index was checked,
leading in some cases to invalid indices and hence mem access, in RNA UV/VCol compute for particles.
Note org code RNA one was copied from (in BI's convertblender.s) is much more complicated,
and seems to never reach those breaking conditions.
Also deduplicated most code in those UV/VCol particles funcs, they were doing mostly the same thing!
Finally, also got rid of annoying `NO CD_ORIGSPACE, error out of range` error message in console,
was another case of not checking whether we did have any faces in final mesh!

Currently this gaussian blur implementation accumulates values in the
square kernel rather that doing X direction and then Y direction because
of the lack of using multiple-staged filters.
Once we can we'll implement a way to apply filter as multiple stages we
can optimize hell of a lot in here.
Another thing we can do is to use SSE2 instructions here.

BKE_scene_base_iter_next() was completely messing poor dupli objects' matrices...
Note this func should be reworked, but as stated in comments, it should not exist at all,
DAG should be used here, so until we have new shinny one we can live with this.
Also, mballs do not behave correctly when used as duplis (org object remains visible/rendered,
unlike any other object type). This will be fixed in a separate patch/commit,
since it proved to be rather tricky to handle.

BKE_mball_basis_find()
BKE_mball_basis_find() was making a bunch of string manipulations for all MBall objects
(including duplis), and then making a (broken!) check to do nothing in case of duplis mball!
Now it makes correct check in early stage.
|
|
mballs, will never be used anyway!

curves' splines and texts' letters.
Useful especially for importer addons.
