- no need to link to scenes when using a frame from the pydriver, this made linking rigs for eg, quite messy.
- advantage that we get subframe values (where scenes from was fixed to a whole number).
existing check for driver to use GIL was not thread safe and could cause, details in the report.
This bug was caused by a check to avoid hanging, a fix for [#27683] that worked in 2.4x because the UI didn't use python to draw while rendering.
Apply a different fix for [#27683], when calling an operator, call PyEval_SaveThread(), then PyEval_RestoreThread() so the GIL can be aquired by threads started by the operator - in this case bake starting a thread that evaluates drivers.
- bpy.app.driver_namespace, read-only dictionary, edit in-place.
- reset on file load and new file.
- on errors the namespace used to be reset, this should not be needed.
simple example.
def driverFunc(val):
return val * val
bpy.app.driver_namespace['driverFunc'] = driverFunc
... now all drivers can access this function.
- Also made it so sys.stdin isnt overwritten anymore, instead the interactive consoel overwrites while it executes and restores after.
- removed hope folder from sphinx patch path
* 'Export Keying Set' operator works again - a change in the previous commit broke the created code
* Relative Keying Sets don't get their paths shown
* Keying Set paths show options for inserting keyframes too now
---
Another attempt at fixing compile troubles, and removed some commented out + obsolete stuff.
Highlights:
* Support for Multi-Target Variables
This was the main reason for this recode. Previously, variables could only be used to give some RNA property used as an input source to the driver a name. However, this meant that effects such as Rotational Difference couldn't be used in conjunction with other effects and/or settings to achieve the powerful results. Now, a variable can take several input targets, perform some interesting operations on them, and spit out a representative value based on that.
* New Variable Types
With the introduction of multi-target variables, there are now 3 types of variable that can be used: single property (i.e. the only type previously), Rotational Difference (angle between two bones), and Distance (distance between two objects or bones).
* New Driver Types
In addition to the existing 'Average', 'Sum', and 'Expression' types, there is now the additional options of 'Minimum' and 'Maximum'. These take the smallest/largest value that one of the variables evaluates to.
* Fix for Driver F-Curve colouring bug
Newly added drivers did not get automatically coloured in the Graph Editor properly. Was caused by inappropriate notifiers being used.
Notes:
* This commit breaks existing 2.5 files with drivers (in other words, they are lost forever).
* Rigify has been corrected to work with the new system. The PyAPI for accessing targets used for the variables could still be made nicer (using subclassing to directly access?), but that is left for later.
* Version patching for 2.49 files still needs to be put back in place.
