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:

== Datablock filters in the headers are now hidden by default ==
This has been done because users were generally not frequently
toggling these, so quick access vs screen-estate cost wasn't really
worth it to have these always showing and taking up space on the
header.
Usage notes:
- To show these again, click on the "Filter more..." toggle.
- The "Filter more..." button DOES NOT affect whether those filters
apply.
Design notes:
- I tried many other button/icon combinations, but those were either
too space-hogging, vague, or had wrong button order.
- I also tried putting a box around these, but there was too much
padding.
- The ordering of the filters has also been modified a bit so that the
group/fcurve-name filters occur earlier in the list, given that
they're used more frequently
== Graph Editor - Use Fancy Drawing ==
Renamed this option to "Use High Quality Drawing" as suggested by
Matt. "Fancy" isn't really descriptive enough.
== Icons for Mode Dropdowns ==
The mode dropdowns in the DopeSheet and Graph Editors now have icons.
- These were important enough (compared to the auto-snap mode) that
some visual decoration was perhaps warranted.
- It makes it easier to see at a glance what mode the view is in
Icon choices:
- In some cases, the icons seem like quite a natural fit IMO (i.e.
outliner<->dopesheet, key<->shapekey editor, grease pencil, fcurve
editor)
- Action Editor uses an "object" icon to indicate that this is object-
level only for now (though I hope to find a way to address this
soon/later). This will be kept like this until then.
- There isn't any icon for drivers, so after trying a few
alternatives, I settled on area-link icon, since it ties together two
entities using some link.
Toggling options on the selection is better done as a generic operator.
Replace ARMATURE_OT_flags_set and POSE_OT_flags_set with WM_OT_context_collection_boolean_set and use menus to access it with specific settings.
This way its easy make a key shortcut which toggles any boolean on any collection - sequences, metaballs, objects, bones etc.
- comment/remove assignments from values to themselves.
- add case break statements (no functional change but some source code checkers notice).
- fix python errors when the sculpt brush is None.
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.
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).
This patch adds anisotropic filtering of textures in the viewport and the BGE. The quality of the filtering is adjustable in the user preferences under System. For more information on anisotropic filtering:
http://en.wikipedia.org/wiki/Anisotropic_filtering
One current limitation of this setup (having the option a user preference) is it makes runtimes more troublesome. Runtimes don't have user preferences set, so for now the blender player defaults to 2x AF. Options will be added later to change this value (probably a command line option).
a) Enable the possibility to remove the "air bubble" around submerged collision object. This feature is enabled as standard for new files. The code was found in elbeem by nudelZ, coded and provided by Nils Thürey (thanks!)
b) Old baked files gets deleted if a new bake gets started (were overwritten before and resulted in weird old bake + new bake mixture) (idea by nudelZ)
=======================
Added option to baked named "Bake From Multires" which is avaliable for
normals baking and displacement baking.
If this option is enabled, then no additional hi-res meshes and render
structures would be created . This saves plenty of memory and meshes
with millions of faces could be successfully baked in few minutes.
Baking happens from highest level against viewport subdivision level,
so workflow is following:
- Set viewport level to level at which texture would be applied
during final rendering.
- Choose Displacement/Normals baking.
- Enable "Bake From Multires" option.
- You're ready to bake.
Displacement baker had aditional option named "Low Resolution Mesh".
This option is used to set if you want texture for realtime (games)
usage.
Internally it does the following:
- If it's disabled, displacement is calculated from subdivided
viewport level, so texture looks "smooth" (it's how default
baked works).
- If it's enabled, dispalcement is calculated against unsubdivided
viewport levels. This leads to "scales". This isn;t useful for
offline renders much, but very useful for creating game textures.
Special thanks to Morten Mikkelsen (aka sparky) for all mathematics
and other work he've done fr this patch!
- fix: user pref, window title was reset to 'Blender' on tab usage
- Undo history menu back:
- name "Undo History"
- hotkey alt+ctrl+z (alt+apple+z for mac)
- works like 2.4x, only for global undo, editmode and particle edit.
- Menu scroll
- for small windows or screens, popup menus now allow to display
all items, using internal scrolling
- works with a timer, scrolling 10 items per second when mouse
is over the top or bottom arrow
- if menu is too big to display, it now draws to top or bottom,
based on largest available space.
- also works for hotkey driven pop up menus.
- User pref "DPI" follows widget/layout size
- widgets & headers now become bigger and smaller, to match
'dpi' font sizes. Works well to match UI to monitor size.
- note that icons can get fuzzy, we need better mipmaps for it
file
This is just a more formalised version of a local hack I've been
running locally for the past year now. It's especially useful when you
want to maintain your own set of recently opened test files (or
perhaps current project files), but then be able to quickly open some
.blend files downloaded from the web (i.e. checking out some bug
report, or how someone else sets up some node setup) without
loosing/polluting your existing recent files list as a result of doing
so, and having to either resort to some nasty methods to get it back.
Of course, this is still really hacky, as for instance, it means that
the currently opened file will not show up in the recent files list
for quick reload. However, that's why this is a userpref :)
The Limit Distance Constraint now has a "For Transform" option just
like all the other Limit constraints. This option controls whether the
constraint gets applied to interactive transforms in the 3D View too,
preventing controllers from getting large values without the animator
knowing.
Additional code changes:
* Split code to get constraint targets and grab their matrices for
solving out to a separate helper function:
get_constraint_targets_for_solving()
* Fixed a bug where "found constraint ...." prints would appear in the
console. Looks like some warning print that was forgotten
TODO:
* While coding this, I noticed potential division by zero bugs with
the Limit Distance constraint. Looking into these after this commit.
Added operator to convert animation for standard object transforms
(i.e. loc/rot/scale) to delta transforms.
This can be accessed from the Object -> Transform -> Animated
Transforms To Deltas menu entry in the 3D View.
Since the situation which causes this is quite common (especially for
motion-graphics type applications), where users animate some object
first and then decide to duplicate this and place it around the place
in different locations, it's probably important that we have some
support for this kind of thing. Newbies with the "help, all my anmated
duplicates disappear" problem are recommended to use this operator
from hereon in.
For reference of rationale, see:
http://blenderartists.org/forum/showthread.php?219126-Move-Existing-f
-Curve-to-delta-equivalent
for durian we had camera rigs which needed to have the parent transformed rather then the camera, for this reason I made fly mode fly the parent rather then the camera its self.
Make this a preference and use this for view camera/view locking too.
