Introduce a method to annotate types and names of entries in the
`bones` container of rig components and apply it, and other type
annotations, to a number of not very complex rig classes.
- Introduce BaseRigMixin as a typed base class for mixins intended
for use in rig classes (using BaseRig as a parent causes issues).
- Introduce TypedBoneDict that does not suppress the unknown attribute
analysis in PyCharm, and use it in a system of subclasses to
annotate the bones in various rigs. BaseBoneDict is necessary
because the annotation affects all subclasses, so TypedBoneDict
cannot inherit from BoneDict with the annotation.
- Add or adjust other type annotations of rig methods and utilities.
- Fix other warnings, e.g. undeclared attributes, excessively long
lines, whitespace style issues and typos.

This is no longer necessary, see: T98554.

For IK controls that move freely in space without being tied to
a parent it makes sense to align the location channels to world
(or root), while keeping rotation channels aligned to the limb
end orientation.
Blender already has a Local Location parenting option for this
very use case, but Rigify wasn't using it. This adjusts the
switchable parent mechanism so that the option works as intended,
and provides a Rigify option that controls its value for IK controls.
Note that now it is possible to enable the Local Location option
directly on the control bones after generation and it will work
correctly - it is not required to enable IK Local Location.

The line was missed when updating in rBA448eeb681 after rBf29a738e2.
Also remove an unneeded import.
|
|
|
|
Use new properties introduced in rBfc5bf09fd88c33.
|
|
|
|
Improve auto-generated UI naming and update basic.pivot, basic.raw_copy
and basic.super_copy. Also allow raw_copy to generate builtin widgets.
|
|
Also make error handling more robust and extend constraint relink mixin.
|
|
Also fix metarig Inherit Scale support in limbs.super_finger.
|

Add support for 5 bone chains to the limbs.paw rig.
Implement a new limbs.rear_paw rig, which provides a three bone IK
mechanism designed to keep the first and third bones nearly parallel
by default (based on a YouTube video by @Pieriko as suggested by
@icappiello).
Implement a limbs.front_paw rig with automation that aims to
keep the angle between second and third bones mostly stable
by default (has influence option), as suitable for front paws.
The horse and wolf metarigs are updated to use these new rig
types, with the horse rig further overhauled by @icappiello.

This will likely be useful in the upcoming new face rigs.
Also fix a bug in the bones module.
|

|

Support easier setting of bone orientation via matrix, inherit_scale,
invert_x/y/z constraint properties, computing a matrix from two axis
vectors, adjusting widget positions, and add a pivot widget.

The main goals are to provide an official way for rigs to
interact in a structured way, and to remove mode switching
within rigs.
This involves introducing a base class for rigs that holds
rig-to-rig and rig-to-bone references, converting the main
generator into a class and passing it to rigs, and splitting
the single generate method into multiple passes.
For backward compatibility, old rigs are automatically handled
via a wrapper that translates between old and new API.
In addition, a way to create objects that receive the generate
callbacks that aren't rigs is introduced via the GeneratorPlugin
class. The UI script generation code is converted into a plugin.
Making generic rig 'template' classes that are intended to be
subclassed in specific rigs involves splitting operations done
in each stage into multiple methods that can be overridden
separately. The main callback thus ends up simply calling a
sequence of other methods.
To make such code cleaner it's better to allow registering
those methods as new callbacks that would be automatically
called by the system. This can be done via decorators.
A new metaclass used for all rig and generate plugin classes
builds and validates a table of all decorated methods, and
allows calling them all together with the main callback.
A new way to switch parents for IK bones based on the new
features is introduced, and used in the existing limb rigs.

Patch suggested by @pioverfour.
|
|
- Added a utility for creating Transform Channel driver variables.
- Added a utility for deriving one bone name from another with suffix.
The bone name utility is inspired by get_bone_name from limb_utils.py

As suggested by @icappielo, and after discussion with @meta-androcto,
I start a public request to commit third-party contributions already
accepted to https://github.com/eigen-value/rigify/tree/rigify_0.6_beta
Specifically, this includes:
* User-defined rig package (feature set) support by @pioverfour.
This allows users to install pre-packaged rig sets via zip
files, which become accessible together with built-in rigs,
as discussed in T52758.
https://github.com/eigen-value/rigify/pull/1
* Modularization of python script generation, allowing rigs to
add their own utility functions and operators to the generated
script. This is critical to make custom rig support really
useful.
https://github.com/eigen-value/rigify/pull/5
* The utils.py file is split into multiple modules with a backward
compatibility proxy for old functions.
* Automatic verification that different rigs don't try to create
different rig settings with the same name to alleviate increased
risk of namespace conflicts with custom rigs.
https://github.com/eigen-value/rigify/pull/7
* New utility class that implements bone layer selection UI.
https://github.com/eigen-value/rigify/pull/6
* New utilities to replace copy & pasted boilerplate code for
creating custom properties, constraints and drivers.
https://github.com/eigen-value/rigify/pull/11
Some other random changes by MAD have likely slipped through.
These changes have already been extensively discussed and accepted
into the branch by @luciorossi, so I see no reason not to commit
them to the official repository to be tested during 2.8 beta.
