deletion of baked caches.
This happens when objects use file names with matching prefixes:
"CubeX" -> not baked
"CubeXYZ" -> baked
The first objects cache should be discarded up to the current frame on
file load, but the second should be left intact. But because the cache
file names for both use the same prefix as well (based on hex name
representation) they both match the "CubeX" name and get discarded.
Adding the underscore terminator solves this issue, because it is never
part of the hex file name string.
WARNING: this solution does not work with custom names for point caches.
This feature is pretty much broken, users have to ensure their names
are unique themselves. Due to the possibility of underscores in names
and the ambiguity of point cache suffixes there is no reliable way to
encode filenames in that case.
There was some stupidness in the way how tracks are synchronized from the job
to actual DNA data leading to all sort of weird and wonderful failures again.
Writing to the tracks was already inside the lock section, but
reading was not. This could have lead to race condition leading
to all sorts of weird and wonderful artifacts.
This hack should not be needed here, quoting Sergey, the actual issue comes from BKE_object_handle_update_ex,
which is calling BKE_object_where_is_calc_ex when it shouldn't.
Propper fix is depsgraph refactor topic, though.
Allocating the iterator from a BLI_memarena wasn't threadsafe.
Change the API to use stack memory for iterators.
Thanks to @mont29 for finding exact cause of the bug.
It turns out that several important modelling addons depend on the assumption
that Grease Pencil data gets created on the active object instead of on scene
level. This commit adds a toggle for setting whether new Grease Pencil data
is created on scene or object level.
These work as follows:
* "Scene" = The behaviour originally introduced as part of the GPencil_EditStrokes
changes. New strokes are added to the scene instead of the active object, making
it easier to manage things when working with Grease Pencil in general.
* "Object" = The previous behaviour (from 2.50 to 2.72), where new strokes are added
to the active object. This is now being reintroduced to soften the transition
for addons out there which have been doing this in a lazy/lax way so far.
Now, what may be slightly confusing are the "fallback" measures in place:
* "Scene" - To ensure that loading old files goes ok without needing a version patch,
if the active object has GPencil data, that will be used in place of the scene's
own GPencil data.
* "Object" - If there was no active object at the time of creating strokes
(for instance, if you delete the active object immediately before drawing),
GPencil data gets attached to the current scene instead.
Since some tweaks may still be needed here, I've decided to bump the subversion
number so that we have a reference point when doing version patches.
On second thought, it is probably still worthwhile to be able to disable GPencil
drawing on strips. By default, GPencil strokes are still shown by default now,
but they can be turned off using this option if it turns out that they are
getting in the way (e.g. a director/animator make some planning notes in the shot
at an earlier stage which are hidden for normal display now, but are still there
popping up sproadically during the animatic).
After double checking the sequencer code, there doesn't seem to be any reason to
exclude these from the sequencer previews. This makes it possible to use the
sequencer to non-destructively chain together difference Grease Pencil animated
shots together without having to render each image sequence first, allowing for
a smoother workflow.
Just in case the initial assumption isn't entirely correct, I've put in place
an extra arg to the relevant functions which can be hooked up to a suitable
option on the scene strip later to turn this on/off as needed.
Really bad issue which meant code could fetch an image buffer from the
stored cache and modify it. Generally sequence image buffers could come
from the cache and should not be modified directly. Easily solved by
scaling a copy of the original.
Couple of issues:
- Fist/last frame calculation was wrong
- Keyframe selection might silently fail leading to unpredictable math
errors all over the place. Now if keyframe selection fails solver wouldn't
run.
OpenGL in background mode is not used, so we can skip mutex lock and filling in
the list which later is never used.
This gives unmeasurable speedup by skipping mutex lock, plus solves memory leak
in the background mode.
This merge-commit brings in a number of new features and workflow/UI improvements for
working with Grease Pencil. While these were originally targetted at improving
the workflow for creating 3D storyboards in Blender using the Grease Pencil,
many of these changes should also prove useful in other workflows too.
The main highlights here are:
1) It is now possible to edit Grease Pencil strokes
- Use D Tab, or toggle the "Enable Editing" toggles in the Toolbar/Properties regions
to enter "Stroke Edit Mode". In this mode, many common editing tools will
operate on Grease Pencil stroke points instead.
- Tools implemented include Select, Select All/Border/Circle/Linked/More/Less,
Grab, Rotate, Scale, Bend, Shear, To Sphere, Mirror, Duplicate, Delete.
- Proportional Editing works when using the transform tools
2) Grease Pencil stroke settings can now be animated
NOTE: Currently drivers don't work, but if time allows, this may still be
added before the release.
3) Strokes can be drawn with "filled" interiors, using a separate set of
colour/opacity settings to the ones used for the lines themselves.
This makes use of OpenGL filled polys, which has the limitation of only
being able to fill convex shapes. Some artifacts may be visible on concave
shapes (e.g. pacman's mouth will be overdrawn)
4) "Volumetric Strokes" - An alternative drawing technique for stroke drawing
has been added which draws strokes as a series of screen-aligned discs.
While this was originally a partial experimental technique at getting better
quality 3D lines, the effects possible using this technique were interesting
enough to warrant making this a dedicated feature. Best results when partial
opacity and large stroke widths are used.
5) Improved Onion Skinning Support
- Different colours can be selected for the before/after ghosts. To do so,
enable the "colour wheel" toggle beside the Onion Skinning toggle, and set
the colours accordingly.
- Different numbers of ghosts can be shown before/after the current frame
6) Grease Pencil datablocks are now attached to the scene by default instead of
the active object.
- For a long time, the object-attachment has proved to be quite problematic
for users to keep track of. Now that this is done at scene level, it is
easier for most users to use.
- An exception for old files (and for any addons which may benefit from object
attachment instead), is that if the active object has a Grease Pencil datablock,
that will be used instead.
- It is not currently possible to choose object-attachment from the UI, but
it is simple to do this from the console instead, by doing:
context.active_object.grease_pencil = bpy.data.grease_pencil["blah"]
7) Various UI Cleanups
- The layers UI has been cleaned up to use a list instead of the nested-panels
design. Apart from saving space, this is also much nicer to look at now.
- The UI code is now all defined in Python. To support this, it has been necessary
to add some new context properties to make it easier to access these settings.
e.g. "gpencil_data" for the datablock
"active_gpencil_layer" and "active_gpencil_frame" for active data,
"editable_gpencil_strokes" for the strokes that can be edited
- The "stroke placement/alignment" settings (previously "Drawing Settings" at the
bottom of the Grease Pencil panel in the Properties Region) is now located in
the toolbar. These were more toolsettings than properties for how GPencil got drawn.
- "Use Sketching Sessions" has been renamed "Continuous Drawing", as per a
suggestion for an earlier discussion on developer.blender.org
- By default, the painting operator will wait for a mouse button to be pressed
before it starts creating the stroke. This is to make it easier to include
this operator in various toolbars/menus/etc. To get it immediately starting
(as when you hold down DKEy to draw), set "wait_for_input" to False.
- GPencil Layers can be rearranged in the "Grease Pencil" mode of the Action Editor
- Toolbar panels have been added to all the other editors which support these.
8) Pie menus for quick-access to tools
A set of experimental pie menus has been included for quick access to many
tools and settings. It is not necessary to use these to get things done,
but they have been designed to help make certain common tasks easier.
- Ctrl-D = The main pie menu. Reveals tools in a context sensitive and
spatially stable manner.
- D Q = "Quick Settings" pie. This allows quick access to the active
layer's settings. Notably, colours, thickness, and turning
onion skinning on/off.
Basically this commit gets rid of most of the derived mesh immediate mode
drawing (cases such as subsurf excluded). Even when VBO is turned off
in user preferences, we still use vertex arrays, which are very similar to
VBOs but memory is client side. Vertex arrays are OpenGL 1.1 so compatibility
is not an issue here.

Basically, our drawing code assumed we always use the edit mesh
materials, which can be different from the derived mesh
materials in modifiers doing overrides. We usually we want to use the
derived mesh when it is available instead.
There are two fixes here for both solid and textured mode. Unfortunately
the fixes do not help to make the display code less labyrinthian but I
expect this "should work" (tm and famous last words)
Solid mode fix is 95% from Bastien, thanks!
This is added in the spirit of the general cycles GLSL system
which is pretty much WIP still.
This will only work on cycles at the moment but generating for blender
internal is possible too of course though it will be done in a separate
commit.
This hasn't been tested with all and every node in cycles, but
environment and regular textures with texture coordinates work.
There is some difference between the way cycles treats some coordinates,
which is in world space and the way GLSL treats them, which is in view
space.
We might want to explore and improve this further in the future.
...also </drumroll>
This patch includes the work done in the terrible consequencer branch
that hasn't been merged to master minus a few controversial and WIP
stuff, like strip parenting, new sequence data structs and cuddly
widgets.
What is included:
* Strip extensions only when slipping. It can very easily be made an
option but with a few strips with overlapping durations it makes view
too crowded and difficult to make out.
* Threaded waveform loading + code that restores waveforms on undo (not
used though, since sound_load recreates everything. There's a patch for
review D876)
* Toggle to enable backdrop in the strip sequence editor
* Toggle to easily turn on/off waveform display
* Snapping during transform on sequence boundaries. Snapping to start or
end of selection depends on position of mouse when invoking the operator
* Snapping of timeline indicator in sequencer to strip boundaries. To
use just press and hold ctrl while dragging.

gpencil_data_duplicate() was being used for gp drawing undo buffers, where using an
exact copy is exactly what we want/need. Instead, the code here now has an additional
arg for determining whether a direct copy is warranted or not.
