Or not? I'm still investigating. I've noticed these things:
- Spine models have a bunch of internal blurring when animating while Temporal Super Resolution is enabled. The kind of stuff you'd expect a velocity buffer to resolve.
- They don't exhibit this issue when Temporal Anti Aliasing is enabled (but other parts of the scene unrelated to Spine have issues).
I haven't yet figured out if this is related to other project settings or material properties. I suspect it isn't Spine specific, but more to do with configuration (or limitations of Unreal engine anti aliasing techniques?).
The problem doesn't appear in the viewport preview of the Actor. Only once its in the game world.
