Ported joeedh's Euler Filter code from Python to C so that this is
more in line with the other Graph Editor tools - i.e. joeedh's version
only worked on the active bone's curves, while standard tools could
work with multiple bones/objects at the same time.
To use this new version of this operator:
1) Select all the F-Curves for all 3 of the components (XYZ) for the
euler rotations you wish to clean up. In the Graph Editor, they must
be one after the other (i.e. you can't have "RotX, RotY, something
else, RotZ")
2) Activate the operator from the Key menu in the Graph Editor
In an old test file I have floating around, this method did not appear
to be good enough to fix a very clear discontinuity in the middle of
the action, so I'll test some additional methods too
tried doing this smarter by validating the property exists in UI code before access but this ended up making it too complicated and also hard to account for possible access without checking every time.
for now just redraw all areas when a user property is changed.
This tool automates the process of copying a pose to successive
keyframes, making it easier for animators to go back and change the
pose for some controls which remain "static" for periods of time.
Previously, animators would need to do a "{Ctrl-Pageup Ctrl-V} *
number_of_static_keyframes" dance for each set of controls that this
happened on, which is not too good ergonomically speaking.
There are two modes exposed via the menu (Pose->Propagate):
- "Pose Propagate" - also known as the 'WHILE_HELD' mode, which
propagates to all keyframes that are holding the same value
- "To Next Keyframe" - which only propagates the pose to the closest
keyframe in the occurring after (but not including) the current frame
Additionally, there are a few other modes that can be used, though
they are less useful for direct use from the UI, though they can be
used via the PyAPI as need be.
---
Also, I did some cleanups in the "Pose" menu to bring it more into
line with the Object mode one. There are some more tweaks that could
still be done here, such as bringing the keyframing operator entries
under a submenu too (as in the Object mode version) to get the length
of this under control.
move calls to the classes register/unregister function into register_class() / unregister_class() and add docs.
also other minor changes:
- remove face sorting keybinding, was Ctrl+Alt+F, this is quite and obscure feature and face order normally doesn't matter, so access from Face menu is enough.
- add commented out call to mesh.validate() in addon template since its useful to correct incomplete meshes during development.

scripts/startup/ is now the only auto-loading script dir which gives some speedup for blender loading too.
~/.blender/2.56/scripts/startup works for auto-loading scripts too.
Modified to only do one lookup.
from Martin:
"Basically, what it does is allow you to add register and unregister class methods to rna types, this way you don't have to rely on module register/unregister methods to setup your types properly (and it makes them easier to move around when reorganizing code and easier to understand what a type does when reading code). This is especially nice for PropertyGroup classes that are added as properties to existing types, you can easily see in their register methods where they are added and removed in their unregister method. Obviously, those two methods are optional, so current code still works fine."
Not really a "bug", but it was on my todo anyways. Based on patch
[#26508] by Campbell, with a few modifications including extending
this to the Action/DopeSheet editor too.
People had trouble finding the 'Create New Directory' operator button in the file browser. Changed this to show the text as well and make button bigger.
Discussed with Campbell, it's not actually bug and it's more about limitation
of topology mirror. It will work properly when both sides of mesh have matching
unique topology.
Added note to tooltip, so now unpredictable behaviour shouldn't confuse users
so much.
Also gray out "Topology mirror" when "X Mirror" is disabled.
creating RNA within draw functions can free existing RNA, crashing blender when this is already used in the UI.
disallowing this so it raises a python exception.
This was being used to dynamically generate addon categories so for now they are hard coded and we need proper enum-functions for python to do this.
'create' was used as prefix and suffix, change dupli list functions to use as suffix, this matches obj.animation_data_create() & obj.animation_data_clear().
obj.create_dupli_list() --> obj.dupli_list_create()
obj.free_dupli_list() --> obj.dupli_list_clear()
Don't use 'create' for object to mesh function since other uses of this are for createing data which stays attached, instead use mathutils style naming convention.
obj.create_mesh() --> obj.to_mesh()
this is not well suited to RNA so this is a native python api.
This uses:
bpy.data.libraries.load(filepath, link=False, relative=False)
however the return value needs to use pythons context manager, this means the library loading is confined to a block of code and python cant leave a half loaded library state.
eg, load a single scene we know the name of:
with bpy.data.libraries.load(filepath) as (data_from, data_to):
data_to.scenes = ["Scene"]
eg, load all scenes:
with bpy.data.libraries.load(filepath) as (data_from, data_to):
data_to.scenes = data_from.scenes
eg, load all objects starting with 'A'
with bpy.data.libraries.load(filepath) as (data_from, data_to):
data_to.objects = [name for name in data_from.objects if name.startswith("A")]
As you can see gives 2 objects like 'bpy.data', but containing lists of strings which can be moved from one into another.
the same, but big changes have happened both on the outside and on the inside.
New UI:
* The old parameters were quite true to the underlying algorithm, but were quite obscure
from a users point of view. Now there are only a few intuitive basic parameters that
define the basic fluid behavior.
** By default particle size is now used to determine the interaction radius, rest
density and spring rest lengths so that it's easy to get stable simulations by simply
emitting particles for a few frames and adjusting the particle size (easy when the
particle size is drawn) so that the fluid appears continuous (particles are touching
eachother).
** Stiffness - in reality most fluids are very incompressible, but this is a very hard
problem to solve with particle based fluid simulation so some compromises have to be
made. So the bigger the stiffness parameter is the less the fluid will compress under
stress, but the more substeps are needed for stable simulation.
** Viscosity - how much internal friction there is in the fluid. Large viscosities also
smooth out instabilities, so less viscous fluids again need more substeps to remain
stable.
** Buoancy - with high buoancy low pressure areas inside the fluid start to rise against
gravity, and high pressure areas start to come down.
* In addition to these basic parameters there are separate advanced parameters that can
either be tweaked relative to the basic parameters (or particle size) or defined
independently.
** Repulsion - the stiffness parameter tries to keep the fluid density constant, but this
can lead to small clumps of particles, so the repulsion keeps the particles better
separated.
** Stiff viscosity - the normal viscosity only applies when particles are moving closer to
eachother to allow free flowing fluids. Stiff viscosity also applies smoothing to
particles that are moving away from eachother.
** Interaction radius - by default this is 4 * particle size.
** Rest density - by default this is a density that the particles have when they're packed
densely next to eachother.
** Spring rest length - by default this is 2 * particle size.
* There are also new options for 3d view particle coloring in the display panel to show
particle velocity and acceleration. These make it easier to see what's happening in the
fluid simulations, but can of course be used with other particles as well.
* Viscoelastic springs have some new options too. The plasticity can now be set to much
higher values for instant deletion of springs as the elastic limit is exeeded. In addition
to that there is an option to only create springs for a certain number of frames when a
particle is born. These options give new possibilities for breaking viscoelastic fluids.
New in the code:
* Most of the fluids code is now thread safe, so when particle dynamics go threaded there
will be a nice speed boost to fluids as well.
* Fluids now use a bvh-tree instead of a kd-tree for the neighbor lookups. The bvh-tree
implementation makes the code quite a bit cleaner and should also give a slight speed
boost to the simulation too.
* Previously only force fields were calculated with the different integration methods, but
now the fluid calculations are also done using the selected integration method, so there
are again more choices in effecting simulation accuracy and stability. This change also
included a nice cleanup of the whole particle integration code.
As the internals are pretty stirred up old particle fluid simulations will probably not
work correctly straight away, but with some tweaking the same level of control is still
available by not using the "relative versions" of the advanced parameters (by default these
are not used when loading old files).
Option for tagging creases (Ctrl+RMB) to also re-unwrap the mesh.
In 2.42 this could be done by setting rt==8 (very hidden), now its a little less hidden (in the toolbar).
