* When clicking on "Animation" items in the Outliner, there's now a
menu containing from which you can change the action used, and
refresh/delete all drivers.
* Moved action-setting logic for AnimData actions to a single utility
function in anim_sys, since this was starting to be done in too many
places already.
* Fixed Outliner refresh bug after changing the active action
* Horrors from the ancient world of deprecated code: object animation offset can't really work correctly with particles unless point cache takes full control of particle system timing.
* Disabled the non-working offset control from effecting particles so that for now particles will work consistently and the offset is only applied to the object.
===== Situation before this patch =====
in the current situation inside the node editor there is a properties panel (press 'n'-key). This pabel displays some information about the node, backdrop and grease pencil. The UI of the property panel is typically vertical oriented. Nodes in the other hand are not oriented in a direction. Both area's are draw via the same draw function.
With some nodes this will create not user-friendly UI. Try the color-balance for instance). The 3 color circles are drawn next to each other, it would be better to draw them below each other.
When creating more complex nodes you don't want to display all handles in the node-panel and in the properties panel. For instance fine-tuning handles you only want to appear in the property panel to reduce place in the node itself.
===== Situation after this patch =====
This patch separates the draw functions of the property panel and the node panel.
When no special draw function is created for the property panel, the draw function of the node will be used as 'fallback'
===== Impact =====
==== BKE_node.h ====
add a new uifunc (called uifuncbut) to the bNodeType struct. The definition is the same as the uifunc.
==== node_buttons.c ====
if the uifuncbut is set, call it. currently calls the uifunc method
==== drawnode.c ====
static void node_composit_set_butfunc(bNodeType *ntype). set the uifuncbut function where needed. When at the end of the method uifuncbut is still empty, set uifuncbut to the uifunc.
===== Final note =====
! PS. this is not limited to the compositor it also works for Materials and Textures !
! PPS. For other branching creating their own node-tree. Please make sure that your uifuncbut is set NULL or a valid draw function !
A mesh can consist out of multiple material. Take a character with clothing's. the skin can be a different material as the different clothing's. During compositing it is a common use-case to only do a part of the composit on only a specific material. Currently this can not be done.
In blender movies this feature is known to be implemented, but until now it never got integrated into trunk.
Proposal
With material index the Blender internal renderer will be capable of creating a buffer containing the material indexes of the first pixel-hit. This will be implemented in the same manner as the object index.
In the compositor the ID Mask node can be used to extract the information out of the Render pass.
Impact
User interface
On the properties-space the next changes will be done
Scene⇒Render layer⇒Passes⇒Material index will be added
Material⇒Options⇒Pass index will be added
DNA
Material struct will get an new field called “index”. this will be a short-type.
Material struct the field pad will be removed.
A new Render-layer pass will be added (bit 1«18)
RNA
Material RNA is updated (based on “pass index” from object)
Render layer RNA is updated (based on IndexOB)
Blender internal renderer
The Blender internal renderer will process the render pass as a copy of the Object index.
Blender compositor
The render layer input will get a new output socket called “IndexMA”
Usage
An example on how to use material index can be found at:
https://svn.blender.org/svnroot/bf-blender/trunk/lib/tests/compositing/composite_materialindex.blend
This is also example of a commit message longer than the commit itself :)
Objects with drivers are now treated as needing updates when the
current frame changes. This assumption has been documented in the
code, and should at least mean that users who try to use drivers for
creating simple time-based expressions that this should work.
Note:
- It is still recommended to create a "cfra" driver variable instead
of actually inlining bpy.context.scene.frame_current into the
expressions. Not only does the latter look rather nasty to type/have
in the expression, but it is also less future-proof for when I get
around to actually working on a beefed-up depsgraph (nothing official
on that front yet...)
* Use the same method as from unlinking actions to do this.
* Split off the make single-user code used for the ID-browser into a
function in blenkernel which can be used elsewhere. Getting materials
to also work using this method proved to be a bit too tricky (due to
the whole messy ob vs obdata situation), so I haven't done that.
Python:
* adds bpy.app.handlers which contains lists, each for an event type:
render_pre, render_post, load_pre, load_post, save_pre, save_post
* each list item needs to be a callable object which takes 1 argument (the ID).
* callbacks are cleared on file load.
Example:
def MyFunc(scene): print("Callback:", data)
bpy.app.handlers.render_post.append(MyFunc)
C:
* This patch adds a generic C callback api which is currently only used by python.
* Unlike python callbacks these are not cleared on file load.
In addition the billboards can be scaled by the particle velocity with optional head and tail factors (similar to line drawing options). This allows for pseudo-motionblur effects.
- Sequencer dynamics: Now it's possible to change the output channels and the resampling quality also increased (previously maximum quality was 44,1 kHz)
- Changed two buffers to use ffmpeg allocation, not sure if that helps somehow.
- Implemented a nice rechanneling solution with unofficial speaker arrangement standards similar to what OpenAL soft has
- Renamend AUD_Channel in the C API to AUD_Handle
- Removed the unlogical 7.2 speaker configuration, that's a hardware only config
This commit adds an experimental effect strip to the sequencer: "Title
Card".
This is useful for adding simple one-line text section headers or
"title cards" (i.e. title + author/contact details) to video clips,
which is often seen in demo videos accompanying papers and/or
animation tests.
See http://aligorith.blogspot.com/2011/06/gsoc11-simple-title-
cards.html for some more details on usage.
Code notes:
- There are a few things I've done here which will probably need
cleaning up. For instance, the hacks to get threadsafe fonts for
rendering, and also the way I've tried to piggyback the backdrop
drawing on top of the Solid Colour strips (this method was used to
keep changes here minimal, but is quite fragile if things change).
Vertex parents were not requesting the original index layer, now do this as
part of depsgraph building, and make constraints with vertex groups use the
same system. Fix is based on patch by Campbell, but with some changes.
##########
original name: "Allow to change the strenght of the "go behind" constraint of the camera actuator"
The camera actuator is an actuator that drive the camera to follow an object, with a set of constraint.
Currently, when the object followed rotate on himself (like a person, or an helicopter), the camera is really slow to go behind (at least 10 seconds).
This patch gives the UI to tweak the strenght of the 'go behind'[named damping] constraint.
