Debating whether this should be posted under the 'Editor' tab, it was decided to register it here because I think that area should only contain more urgent issues.
What are your thoughts on Shape Key?
I've explored various tools for handling 2D animation.
Spine is already great since the addition of physics, but with Shape Key, I think it will be a masterpiece.
There are two cases where I felt the need this.
- Working about multiple directions, such as "open mouth"... more conveniently!
- Additional work for weighted "vertex pies" where everything is already fine-tuned and nothing is empty place!
It seems that Shape Key could be implemented with a bunch of little tweaks and combinations of existing features and a bit of UI addition.
The basic idea involves inserting the animation parameters from 0 to 100.00 (Percent) and 0.00 to 1.00 (Multiplier) into other animations.
By default, user can manually entering numbers for Percent and Multiplier.
To make things more interesting, user could also use constraints to trigger Shape Key based on the specific Bone's Start to End position, angle, or scale.
If there is concern about everything becoming chaotic, this feature could be made visible only in 'Animation Edit' mode, and constraints related to the currently editing animation is disabled.(= No circular references)
Additionally, if there's constraint option to choose whether to use Percent or Time would be nice.
I know what I'm going to hear now: "There's a good API implementation, use it."
Indeed, making use of the runtime API is fascinating.
However, I have a small hope that the day will come when I can do everything inside the editor via Shape Key.
