Hi there,
Quote:When ObiSolver is set on LateUpdate (no Interpolation) we see one frame late? Can you elaborate on this? is the animation one frame late, or the simulation? Quote:When ObiSolver is set on FixedUpdate with Interpolation, fixed particles are not interpolated - this leads to all simulated particles working as charm, but fixed are jump-following parent object. Fixed particles follow the skeletal animation. Skeletal animation does not support interpolation when working with physics (Unity's limitation), so these particles do not benefit from interpolation, as they are not simulated but animated. Pretty much all of Obi is multithreaded. Interpolation typically takes less than 1% of frame time as it is a very simple operation. It works just like Unity's rigidbody interpolation: since physics are updated at a fixed frequency, it calculates what percentage of a physics update step it would take to get physics and rendering in perfect sync, then it uses this value to linearly interpolate between the last step's positions and the current step positions. For more info on physics, frame interpolation and extrapolation see: https://gafferongames.com/post/fix_your_timestep/

Hello,
we put together simple scene to demonstrate our situation (will send it to the support@virtualmethodstudio.com). In the example, there is a Cube - to simulate the player. We are simulating movement on simulaton rig and using our own interpolation - Lerping/Slerping over time (attached in the example) to apply smooth movement to the render rig because of networking. Description of the scene: a. Moving the simulaton rig in fixed update. b. Own interpolation of the a. and copying the transforms to the render rig. c. Cloth object position is copied from the simulation rig "bone" in fixed update. d. Cloth simulation in fixed update with your interpolation. Observation 1. We have to use skinned mesh with "fixed paricles" being substitued with "skin radius" set to 0, to avoid jump-following of the "fixed paricles" - not happy with that, because we cannot use "fixed particles" Observation 2. Your interpolation seems to be dependant on "Fixed Timestep" - when 0.02, the interpolated cloth is working fine, - on lower value, the interpolated cloth is few steps ahead of our interpolation - on higher value, the interpolated cloth is s few steps behind of our interpolation Could you please take a look on the example and recommend setting for this setup? The asset is great and powerfull tool. Thanks

Hello,
Could you please help us find proper setting for explained setup? Thanks, Kind Regards,

Hello josemendez,
could you at least provide us your interpolation logic (script) for us to be able to unify the delay issue? Is there a way to replace it/rewrite it with our logic? Thanks, Kind Regards.
