I am using Playables for animations in my game. I have a playable graph where all clips are connected to root playable. When i dont need some animation, i set its weight to zero.
Question - does zero weight animations still use resources or they are internally discarded when blending?
I beleive that animation blending is not performed in this case. All available releated source code (old DOTS Animation package and Animation Rigging package) shows such approach.
The performance tests I did for Animancer showed fairly small differences, but generally better performance for disconnecting playables instead of leaving them at 0 weight. I expect there is some optimization for weightless connections of the differences would be much larger, but it seems that some parts of the system must still use a bit of time processing them.
