Currently B-Bone scaling can only be controlled via their
properties, thus requiring up to 8 drivers per joint between
B-Bones to transfer scaling factors from the handle bone.
A Scale Easing option is added to multiply the easing value
by the Y scale channels to synchronize them - this produces a
natural scaling effect where both the shape of the curve and
the scale is affected.
In addition, four toggles are added for each handle, which
multiply each of the X, Y, Z and Ease values by the matching
Local Scale channel of the handle bone, thus replacing trivial
drivers. The Scale Easing option has no effect on this process
since it's easy to just enable both Length and Ease buttons.

In addition to the base bone transformation itself, B-Bones have
controls that affect transformation of its segments. For rotation
the features are quite complete, allowing to both reorient the
Bezier handles via properties, and to control them using custom
handle bones. However for scaling there are two deficiencies.
First, there are only X and Y scale factors (actually X and Z),
while lengthwise all segments have the same scaling. The ease
option merely affects the shape of the curve, and does not cause
actual scaling.
Second, scaling can only be controlled via properties, thus
requiring up to 6 drivers per joint between B-Bones to transfer
scaling factors from the handle bone. This is very inefficient.
Finally, the Z channels are confusingly called Y.
This commit adds a B-Bone Y Scale channel and extra B-Bone flag
fields to DNA with appropriate versioning (including for F-Curves
and drivers) in preparation to addressing these limitations.
Functionality is not changed, so the new fields are not used
until the following commits.

Add translation/rotation/scale parameters for custom bones shapes. The
new scale is a 3D vector `custom_shape_scale_xyz`, and replaces the
`custom_shape_scale` float.

Allow setting drivers and keyframes for the bone visibility restriction
icon in the outliner. Before the button was a simple icon button, but it
is now connected to the RNA property to show the driven or keyframed
state.
Also when hiding a bone from the outliner it would be deselected, but
from the properties editor it would remain selected. This moves the
deselection to the RNA update function to ensure the bone is always
deselected.

The layout was somewhat poor - hard to see what relates to the custom object, and also weirdly we show the Wireframe toggle above the Custom Object control, even though it can only be active if a bone has a custom object set.
Instead, I grouped everything in a Custom Shape sub-panel and used greying out.

As an inherent property of matrix-based transformation math, non-
uniform scaling of a parent bone induces shear into the transform
matrix of any rotated child. Such matrices cannot be cleanly
decomposed into a combination of location/rotation/scale, which
causes issues for rigging and animation tools.
Blender bones have options to exclude rotation and/or scale from the
inherited transformation, but don't have any support for removing the
often undesired shear component. That goal requires replacing simple
parenting with a combination of multiple bones and constraints. The
same is true about the goal of inheriting some scale, but completely
avoiding shear.
This patch replaces the old Inherit Scale checkbox with a enum that
supports multiple options:
* Full: inherit all effects of scale, like with enabled Inherit Scale.
* Fix Shear: removes shear from the final inherited transformation.
The cleanup math is specifically designed to preserve the main
axis of the bone, its length and total volume, and minimally
affect roll on average. It however will not prevent reappearance
of shear due to local rotation of the child or its children.
* Average: inherit uniform scale that represents the parent volume.
This is the simplest foolproof solution that will inherit some
scale without ever causing shear.
* None: completely remove scale and shear.
* None (Legacy): old disabled Inherit Scale checkbox.
This mode does not handle parent shear in any way, so the child
is likely to end up having both scale and shear. It is retained
for backward compatibility.
Since many rigging-related addons access the use_inherit_scale
property from Python, it is retained as a backward compatibility
stub that provides the old functionality.
As a side effect of reworking the code, this also fixes a matrix
multiplication order bug in the Inherit Rotation code, which caused
the parent local scale to be applied in world space. In rigger
opinion this option is useless in production rigs, so this fix
should not be a problem.

Make the transforms section of the properties panel consistent with
the transforms section of the side-bar, and to expose some currently
hidden BBone properties in the Bendy Bone section.
- Object transformations were not consistent with Pose Bone
transformations in that they did not use single-column layout.
- Even in Pose Bone transformations,
the rotation mode option was after Scale.
- Edit Bone Transforms panel included "Tail Radius" and
"Envelope Deform Distance", neither of which belong there. See T65670.
- Expose bbone_x and bbone_z.

As far as I can tell, there is no technical reason why the B-Bone
segment thickness scaling can't be separated into two axes. The
only downside is the increase in complexity of the B-Bone settings,
but this is inevitable due to the increase in flexibility.
Updating the file is somewhat complicated though, because F-Curves
and drivers have to be duplicated and updated to the new names.

Neither is very descriptive for its task, but at least workbench is more

@jpbouza was rather upset these were made read-only, and unlike
parents, it's not that hard to allow changing these Bone fields:
all is needed is to carefully refresh the matching fields in the
relevant bPoseChannel objects and properly tag update.

Custom handle settings actually affect the B-Bone rest shape,
so they should be changed in Edit mode rather than Pose mode.
This is necessary to be able to display the correct rest shape
of the bone in Edit Mode.
Also, instead of flags, introduce an enum to specify the handle
operation modes, so that new ones could be added later.

There was a mistake when the UI was converted to the new layout style.
|
|
This is intended for quick renders for previsualization, animation previews
or sequencer previews. It provides the same settings as found in the 3D view
Shading popover in solid display mode, but in the scene render properties.
The "Workbench" engine was removed, and this name no longer appears in the
user interface, it's purely an internal name. We might come up with a better
name for this OpenGL engine still, but it's good to be consistent with the
OpenGL Render operator name since this has a similar purpose.

The ClayEngine was introduced to test the blender2.8 architecture during
development. As currently we have the wanted features implemented with
matcaps we are going to remove the clay engine as it was never intended
to be an official releasable engine
Note: The test cases are never run. But when enabled will be skipped as
they were implemented over the Clay Engine

This caused too many problems syncing object modes
with multiple objects/windows/workspaces, see: D3130 for details.
|
|
- Read-only access can often use EvaluationContext.object_mode
- Write access to go to WorkSpace.object_mode.
- Some TODO's remain (marked as "TODO/OBMODE")
- Add-ons will need updating
(context.active_object.mode -> context.workspace.object_mode)
- There will be small/medium issues that still need resolving
this does work on a basic level though.

This fix enables the usage of bbones easing parameters for edit and pose mode seperately. This allows animators to take advantage of the functionality and may eliminate confusion as the parameters now behave similar to other bbone parameters.
Note that splitting the parameters between the modes effectively creates a new parameter set. Blend files of previous versions do not contain this information and will have the values set to 0 on load. As it broke backwards compatibility for pose mode values anyway, I also took the liberty to rename the easing parameters in some places for consistency (which breaks edit mode values).

Physics panels are not all back, and the material related panels (e.g.,
hair render panel) should go be changed since there should be no
material for those.
|
|
Although this wasn't so obvious since it
only showed up for factory settings and in the preferences window.
Panel display order depends on registration order,
Sorry for the noise. On the bright side we no longer need to move
classes around to re-arrange panels.

Change the order of the bending controls ("Curve XY Offsets") so the user can activate both InX and OutX by holding down the left mouse button. This way, it's easy to bend symmetrically on X or Y.

This commit/patch/branch brings a bunch of powerful new options for B-Bones and
for working with B-Bones, making it easier for animators to create their own
rigs, using fewer bones (which also means hopefully lighter + faster rigs ;)
This functionality was first demoed by Daniel at BConf15
Some highlights from this patch include:
* You can now directly control the shape of B-Bones using a series of properties
instead of being restricted to trying to indirectly control them through the
neighbouring bones. See the "Bendy Bones" panel...
* B-Bones can be shaped in EditMode to define a "curved rest pose" for the bone.
This is useful for things like eyebrows and mouths/eyelids
* You can now make B-Bones use custom bones as their reference bone handles,
instead of only using the parent/child bones. To do so, enable the
"Use Custom Reference Handles" toggle. If none are specified, then the BBone will
only use the Bendy Bone properties.
* Constraints Head/Tail option can now slide along the B-Bone shape, instead of
just linearly interpolating between the endpoints of the bone.

- Custom scale:
Avoids having multiple custom-shapes at different sizes.
- Option not to use bones length:
So changes in edit-mode don't resize the custom-shape.

New Bone option: "Relative Parenting".
This makes Child-Objects of Bones transform similar to how deformations
of bones are calculated. Allows to move bones in editmode to set pivot.
The option is in Bone Panel, with clear label.
It is ON now by default when you add new bones
Requested by Kjartan, our famous robot designer :) For "hard body rigs" it's
very useful.

* Rename Legacy to Standard, it's not being deprecated as far as I know.
* Make option to toggle off Location solving work with Standard.
* Make it converge a bit better in some cases by enforcing a minimum number of
iterations before giving up.
* Move IK solver choice out of bone panel, it's an armature level setting and
should be set there.
