Original patch by Jan Diederich, adapted by Pelle Johnsen. Review assistance by Daniel Tavares.
This patch adds an option to export only the selection.
It is now possible to create "scripted expression" drivers by simply
clicking on some property, and typing some short Python expression
prefixed with a '#'. This will result in a scripted expression driver,
with the typed-in text being created.
For example, you can click on X-Location of the default cube, and
type:
#sin(frame)
and a new driver will be created for the x-location of the cube. This
will use the current frame value, and modulate this with a sine wave.
Do note though, that the current frame is a special case here. In the
current implementation, a special "frame" driver variable, which
references the current scene frame is created automatically, so that
this simple and (assumed) common case will work straight out of the
box.
Future improvements:
- Explore possibilities of semi-automated extraction of variables from
such expressions, resulting in automated variable extraction. (Doing
away with variables completely is definitely 100% off the agenda
though)
- Look into some ways of defining some shorthands for referencing
local data (possibly related to variable extraction?)
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...)
* Removed frame-number display from NLA strips. Indeed doing so makes
things look cleaner/easier to identify.
* When transforming NLA strips, the "temp-metas" (purple strips) get
their frame extents drawn on either end, like in the sequencer, which
seems to be easier to read than the ones inside the strips.
---
The downside of this tweak is that there is no longer any visual
feedback for which strips run reversed instead of forwards, as that
used to be shown using the frame extents stuff.
The Keying Set paths list now shows the icon of the type of ID-block
that a path item refers to. This make it easier to make snese of the
paths shown in the list.
Animation Editor toggle tweaks:
* By popular request, curve visibility toggles in the Graph Editor are
now represented using the eyeball icons
* Muting is now represented by a speaker icon (a speaker for this
purpose seems fairly common?)
New icons:
* Keying Sets now have their own icons (as found in a proposal on
jendrzych's "Pixel Sized" blog)
* Drivers also have their own icon now. This is just a hacky one I've
devised which doesn't look that great. Suggestions on this are very
welcome.
Closed regions didn't always draw the (+) icon right place, confusing
for users.
Next to that, I think this icon is using a bad metaphor or visual language,
Illustrated best if you close a header in outliner or buttons. Icons are
UI widgets, for screen/editor layouts different controls can be stylized.
My preference is something that aligns visually to the seperators between
regions; for testing and hacking pleasure I've added two quick versions,
a small tabbish thing and a triangle. Enable these with debug menu,
ALT+CTRL+D, values 1 or 2.
This is simply drawn with opengl now. An image for it can be made as well.

There's other design ideas to explore as well, like making region deviders
8-10 pixels wide, with a 'drag me' dot on it or so. That takes some screen
estate though, and will require to add big editor-dividers too...
Fun stuff for the mockup-mafia to check on, we have time :)
Channels can now be used as "animation containers" to be filtered
further to obtain a set of subsidiary channels (i.e. F-Curves
associated with some summary channel).
The main use of this is that object and scene summary channels can now
be defined without defining the filtering logic in three different
places - once for channel filtering, once for drawing keyframes in
action editor, and once for editing these keyframes.
An indirect consequence of this, is that the "Only selected channels"
option in Timeline will now result in only the keyframes for a
selected bones getting shown (when enabled), instead of all keyframes
for the active object. This was requested by Lee during Durian, and is
something which has only become possible as a result of this commit.
* After changing driver target settings, the driver F-Curves now have
their "disabled" flags cleared, so that they will be updated
immediately instead of needing a manual "Update Dependencies" flush
* Little comment tweak to appease my text editor
render strands use the window matrix and window size which were both zero while baking, this caused divides by 0 and eternal malloc loop.
So set unit window matrix and dummy view size.
This is more a workaround then a fix but avoids crashing.
* F-Curves no longer show the name of the datablock of the property
they affect if this is an ID-block. For example, transform curves for
a cube won't get the "... (Cube)" suffix anymore. In these cases, it's
relatively clear that these belong to the parent datablock, so doing
this should be fine (and reduces clutter).
However, for non-id data (i.e. subsurf modifier settings) or bones,
this info still gets shown. In these cases, there is some ambiguity.
* "ActiveAct: <...>" is no longer shown for NLA action channels (i.e.
just the name of the action gets shown). This should make it easier to
see at a glance what action is being used.
== 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.
* 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.
