By popular demand, the CLean Keyframes operator will now
leave handles and other interpolation settings untouched.
Previously, it would recreate the keyframes from scratch,
keeping only the frame + value, under the assumption that
the handle information was "bad" (i.e. the source of bumps
and roughness, due to bad hand tweaking). However, since
most animators use this on hand-keyed animation instead of
motion-capture data, this assumption didn't hold, and was
actually overly destructive - wiping out lots of hand-adjusted
curve data.
Notes:
* Really need to address RNA setters case, end up adding way too much
G.main here these days... :/
* Added Main pointer into bAnimContext, helps a lot in anim code ;)
There were 2 issues here (first was the one reported):
1) Curve shape changes if multiple consecutive pairs of keyframes
are selected. The problem is that after the first pair is handled,
subsequent pairs get sampled on the basis of the modified curve.
2) With multiple separate "islands" selected, unselected points in between
would get ignored, causing the entire curve to get sampled.
To make it easier for animators working in a multipass pose-to-pose workflow
when inserting breakdown keyframes and so forth, it is now possible to specify
the "type" of keyframe being created (i.e. the colour of the keyframe, when drawn
in the Dope Sheet).
Usage:
1) Choose the type of keyframe ("Keyframe", "Breakdown", "Extreme", etc.) from
the new dropdown located between the AutoKeying and KeyingSet widgets on the
timeline header.
2) Insert keyframes
3) Rejoyce that your newly created keyframes have now been coloured for you already
in the DopeSheet.
Todo:
* Look into a way of using the actual keyframe colours (from the theme) for the icons
of these types.
Basically it's a clean keyframes tool, but also removes a channel if the
only remaining keyframe has the default value only and is not used by
drivers or generative modifiers.
It's was used to help with performance of keyframe-heavy scenes in
gooseberry.
Note, as always the curve left after the clean tool is used is not the
same as the original, so this tool is better used before doing custom
editing of fcurves and after initial keyframe insertion, to get rid
of any unwanted keyframes inserted while doing mass keyframe insertion
(by selecting all bones and pressing I for instance)
and graph editor.
This was a tricky commit that was not so straightforward to make work.
The information for bones is not easy to come by in the animation curves,
however we do have some string manipulation tricks to make it happen.
Testing in gooseberry worked for the rigs there, commiting to master now
Added an extra option to `insert_bezt_fcurve()`, to allow full override of existing
keyframes when pasting (in this case, we do not want to inherit handles from existing
curve!).
This makes a number of operators no longer ask for confirmation, rather it will
show an info message after performing the operation. Ref T37422 for decision. In
particular, these were changed:
* Delete objects, bones, keyframes, masks, mask curves, motion tracks, markers.
* Clear and delete keyframes in the 3D view.
* Align bone to parents.
* Separate bones from armature.
* Group/ungroup metastrips in sequencer.
* Copy/paste objects to/from buffer.
