bake_constraints
|
|
|
|
This script bakes the real-world LocRot of an object (the net effect of any constraints -
|
|
(Copy, Limit, Track, Follow, - that affect Location, Rotation)
|
|
(usually one constrained to match another's location and/or Tracked to another)
|
|
and creates a clone with a set of Ipo Curves named Ipo<objname>
|
|
These curves control a non-constrained object and thus make it mimic the constrained object
|
|
Actions can be then be edited without the need for the drivers/constraining objects
|
|
|
|
Developed for use with MoCap data, where a bone is constrained to point at an empty
|
|
moving through space and time. This records the actual locrot of the armature
|
|
so that the motion can be edited, reoriented, scaled, and used as NLA Actions
|
|
|
|
see also wiki Scripts/Manual/ Tutorial/Motion Capture <br>
|
|
|
|
Usage: <br>
|
|
- Select the reference Object(s) you want to bake <br>
|
|
- Set the frame range to bake in the Anim Panel <br>
|
|
- Set the test code (if you want a self-test) in the RT field in the Anim Panel <br>
|
|
-- Set RT:1 to create a test armature <br>
|
|
-- Set RT: up to 100 for more debug messages and status updates <br>
|
|
<br>
|
|
- Run the script <br>
|
|
- The clone copy of the object is created and it has an IPO curve assigned to it. <br>
|
|
- The clone shadows the object by an offset locrot (see usrDelta) <br>
|
|
- That Object has Ipo Location and Rotation curves that make the clone mimic the movement <br>
|
|
of the selected object, but without using constraints. <br>
|
|
- If the object was an Armature, the clone's bones move identically in relation to the <br>
|
|
original armature, and an Action is created that drives the bone movements. <br>
|
|
|
|
Version History:
|
|
0.1: bakes Loc Rot for a constrained object
|
|
0.2: bakes Loc and Rot for the bones within Armature object
|
|
0.3: UI for setting options
|
|
0.3.1 add manual to script library
|
|
0.4: bake multiple objects
|
|
0.5: root bone worldspace rotation
|
|
0.6: re-integration with BPyArmature
|
|
0.7: bakes parents and leaves clones selected

|
|
much lifted/learned from blender.org/documentation/245PytonDoc and wiki
|
|
some modules based on c3D_Import.py, PoseLib16.py and IPO/Armature code examples e.g. camera jitter
|
|
|
|
Pseudocode:
|
|
Initialize
|
|
If at least one object is selected
|
|
For each selected object,
|
|
create a cloned object
|
|
remove any constraints on the clone
|
|
create or reset an ipo curve named like the object
|
|
for each frame
|
|
set the clone's locrot key based on the reference object
|
|
if it's an armature,
|
|
create an action (which is an Ipo for each bone)
|
|
for each frame of the animation
|
|
for each bone in the armature
|
|
set the key
|
|
Else you're a smurf
|
|
|
|
Test Conditions and Regressions:
|
|
1. (v0.1) Non-armatures (the cube), with ipo curve and constraints at the object level
|
|
2. armatures, with ipo curve and constraints at the object level
|
|
3. armatures, with bones that have ipo curves and constraints
|
|
4. objects without parents, children with unselected parents, select children first.
|
|
|
|
Naming conventions:
|
|
arm = a specific objec type armature
|
|
bone = bones that make up the skeleton of an armature
|
|
|
|
ob = object, an instance of an object type
|
|
ebone = edit bone, a bone in edit mode
|
|
pbone = pose bone, a posed bone in an object
|
|
tst = testing, self-test routines
|
|
usr = user-entered or designated stuff
