Cache Retime + Animated objects + tyflow _ Issue - chriss3d - 06-02-2022
Hello
I have simple growing plant setup.
Animated (manually) trunk (spline+ animated tySplineMesher) and animated leaf geo attached to tySplineMesher geo (leaf animation is baked via max Point Cache - 4 samples per frame).
All works fine simulates and caches.
The problem starts when I try to retime tyCache .
I noticed that animated tySplineMesher retimes just fine and smooth (4x slow down) but the animated leaves are not.
The leaves jitters like there is no enough samples being baked into tyCache from the geo. I did check "smooth subframe interpolation" under Shape op but no difference.
Please check the video.
Any clue ?
Thank You,
Best
Chris

Looks like you're trying to retime Shape operator animation....that seems to be what is jittering (since you can see the leaves themselves transform smoothly along the vine, it's only the deformations that are jittery). Currently tyCache doesn't do any subframe interpolation of deforming shapes during retimes.
If the particle count doesn't change (you don't birth leaves over time....only scale them up), you could put a Point Cache modifier on the leaves and retime them using the Point Cache playback graph, similar to how you'd retime a tyFlow using the graph method. Will that work with your setup?

Thanks for reply Tyson !!
Your approach might work, but in my project I got to to build all kind of speed growth variations, as an assets database, which then needs to be shared across the team to build individual scene layouts with individual timings.
I thought that the tycache would be the best since each artist could individually animate the growth speed themselves.
In my case I think than making a slow mo version of the animation would be better approach, because I will bake enough samples in tycache and then speed up can be applied with no harm to animation integrity.
I hope we will get supersampling geo baking implemented in the future
Thanks
