(The choppiness is for effect. Imagine a trail following the sword.)
It took me all day but I made some progress with procedural animation. In the image above I am only animating 3 properties:
- Goal L Hand Position
- Goal R Hand Position
- Goal R Hand Rotation
All three are just empty Game Objects that are being tracked by a script. Every LateUpdate the script updates a component from an awesome plugin called FinalIK. Finally, the red stick is nested in the Right Hand Goal Game Object.
We'll see if it's feasible to continue down this path.
