Fixes for bugs in #7833
- Hair softbody cache was reset on rendering.
- When Alt-a playback is synced to audio frames are skipped. This caused dynamics caching to go crazy. Now the first loop of playback goes through all frames if there are non cached dynamic systems.
Invalid point caches weren't cleared when new systems were created. This caused messed up shapes when softbody was added.
==========
- Added a Mute button for shape keys, useful for debugging the influence
of driven shape keys.
- Bugfix for the shape keys relative to others keys, was hanging in
an eternal loop when deleting the other key.
Restoring the "evil src splitting hack" for scons+mingw systems. By default, it is not used, but if your system is choking when trying to link src, then add BF_SPLIT_SRC=1 to your user-config.py to use this hack.
=============
A new "Selected to Active" option in the Bake panel, to (typically) bake
a high poly object onto a low poly object. Code based on patch #7339 by
Frank Richter (Crystal Space developer), thanks!.
Normal Mapping
==============
Camera, World, Object and Tangent space is now supported for baking, and
for material textures. The "NMap TS" setting is replaced with a dropdown
of the four choices in the image texture buttons.
http://www.blender.org/development/current-projects/changes-since-244/render-baking/
in EditButtons, panel "Links and Materials", there's now a browse button
to directly assign a material to selected faces. It does:
- check if material was already in one of the 'slots' of the object
- if so, then use this as index to assign
- if not, then add a new slot, and assign the new index
-> Constraint Influence Ipo now can be local, linked to constraint itself
You enable this in the IpoWindow header, with the Action icon to the left
of the Ipo Type menu. The button tooltips give the clue as well.
Tech note: the Ipo now can get directly linked to a constraint, and is
being called during regular pose constraint solving.
Actions (and drivers in actions) are being calculated *before* pose
constraint solving. Result of actions then is written in bones, which
then solves the entire pose.
This means you can have a driver on both the constraint, as on the action
channel for the constraint! Not that I'm going to debug that easily :)
Additional fix: Joshua added a copy/paste IpoCurve feature, but he broke
the functionality to be able to paste in an empty ipo channel. That now
works again
- update for new particle system
- made blenderplayer.exe compile again (DDS library missing)
- exchanged a few float math functions (logf, sinf, cosf, expf, powf) with their double counterparts in CMP_nodes
(MSVC chokes on them, because the compiler is not C99 compliant)
Object panels were using object_data_is_libdata, which meant linked obdata could not have object settings changed.
curve2tree
- option to face leaves up or down
- random pitch and roll options
- place 2 leaves on a point for denser leaves
- random seed entry so you can get reproducible results
=========
- Fix for child particles disappearing with right mouse drag translation.
- Added partial cache updates for selection, should make it a bit faster.
=========
- Fix crash with the cut tool and child particle drawing.
- Make the "Col" option to use material colors work for
the path/hair visualisation type.
=========
- Fix for bug #7837: circle drawtype + velocity crashed.
- Setting density vertex group didn't do proper refresh.
Mesh Deform Modifier
====================
- Make it work for nurbs and curves.
=========
- Fix for bug #7840: adding particle system to nurbs, curves crashes.
Now simply doesn't allow to add a particle system to a non-mesh
object, the current code does not support it.
- Fix for bug #7834: deleting vertices of an object with a particle
system crashes. Fixed by disabling particle display for objects in
editmode.
- Fix for the particle add brush on subsurfed objects.
=========
- Fix for bug #7832: boids physics crashed.
- Bugfix for child particles not getting orco texture coords.
- Allow smaller strand sizes in blender units.
- Fix for a common but harmless uninitialized value warning in
valgrind, in the event queue.
=========
Merge of the famous particle patch by Janne Karhu, a full rewrite
of the Blender particle system. This includes:
- Emitter, Hair and Reactor particle types.
- Newtonian, Keyed and Boids physics.
- Various particle visualisation and rendering types.
- Vertex group and texture control for various properties.
- Interpolated child particles from parents.
- Hair editing with combing, growing, cutting, .. .
- Explode modifier.
- Harmonic, Magnetic fields, and multiple falloff types.
.. and lots of other things, some more info is here:
http://wiki.blender.org/index.php/BlenderDev/Particles_Rewritehttp://wiki.blender.org/index.php/BlenderDev/Particles_Rewrite_Doc
The new particle system cannot be backwards compatible. Old particle
systems are being converted to the new system, but will require
tweaking to get them looking the same as before.
Point Cache
===========
The new system to replace manual baking, based on automatic caching
on disk. This is currently used by softbodies and the particle system.
See the Cache API section on:
http://wiki.blender.org/index.php/BlenderDev/PhysicsSprint
Documentation
=============
These new features still need good docs for the release logs, help
for this is appreciated.
- [#6112] is this an extrusion bug?
When extruding, x-mirror was giving weird behavior since the extruded vertice could match with their non-extruded counterpart on the other side.
The solution is to disable x-mirror (with a transform context flag, like disabling PET) in that case.
- External constraint setup calls (BIF_*) didn't setup some internal structs properly.
For the user, this resulted in some transform (extrude particularly) showing a full 3d vector in the header instead of a scalar along the constraint axis (this messed up num input a bit too, you could type values in unused axis).
Added a keyword argument for mesh.pointInside(point, selected_only=True)
This means only selected faces are tested when doing the inside/outside test, disabled by default.
- treat file passed as parameter the same as if loaded from UI if Blender isn't running in background mode.
- only set relative base as valid if file loaded successfully.
Fixed very old annoyance in alpha render: when using alpha textures images,
nicely premulled as Blender wants it, you still got dark outlines at the
edges. This because the blender shading pipeline also premultiplies.
Solution: de-premul image texture colors after sampling.
Scaled action times were getting calculated twice, which meant that translating a keyframe resulted in the keyframe "not following the mouse position".
NLA Window, Strip blending mode "Add" didn't work at all.
It was using very bad quaternion addition. Replaced with proper code.
For devs; new is the function QuatMulFac(quat, factor) which allows to
multiply a rotation with a value (make it rotate more or less)
Peach Request: Bone path lines are now drawn using two colours to show the parts of the path before and after the current frame. Those before the current frame are drawn darker, while those after are drawn in a blue colour.
Patch by: Teppo Kansala (teppoka)
This patch adds X-Axis Mirror support for the following tools:
- Delete Bone (X)
- Recalculate Bone Roll Angles... (Ctrl-N)
- Duplicate Bone (Shift-D)
- Clear Parent... (Alt-P)
- Move Bone To Layer (M)
Mesh.c - mesh.faces.extend([..., smooth=True]) - smooth keyword argument, in a number of places was looping through all faces just to smooth them.
mesh_skin.py - smooth by default
Patch by: Matt Ebb (broken)
Currently in Blender, NLA action modifiers can work in very wacky and mysterious ways.
If an action is being modified with a path deform, when it reaches the end of that strip, it will snap back to the original un-modified location, regardless of whether the strip 'Hold' option is on. It's very frustrating to work with, and causes all sorts of problems - if you use a path to make a character walk from point A to point B, you generally want him to stay at point B, and not jump somewhere completely different, just because the strip ended.
This patch fixes this behaviour, and makes it much more sensible and predictable. There is a chance that this will break old files that were reliant on the old broken behaviour though, but I think it's definitely worthwhile to fix this problem.
Check the demo file in Blender 2.45 vs one with this patch applied - you can see the difference in behaviour.

The 'Only Needed' option for Auto-Keyframing now works better with a few of the different transform options.
Rotating/Scaling using a pivot point that is not the center of the Object/Bone (3d-cursor, active), also inserts location keyframes if the location also changes. If "Only Centers" option is activated, then only location keyframes are inserted.
Relative shapekeys now allow to define the Shape it is relative to!
(It used to be relative with respect to the first key, which is still
default).
The reason for this feature is that keys don't always add together
well when they're all derived from the same base shape. A clear
example is hard to make... will wait for someone posting it. :)
