Network Transform Jittery Movement


I'm checking out the Sample: Fusion Application Loop.

I've found out that the character movement is jittery and looks weird:

After some tests, I found out that when I change the settings of the Interpolation Data Source in the Network Transform component to "No interpolation", the issues are fixed.

Normally, the sample is built according to Fusion documentation recommendations.

Can anybody explain what is the reason for this jittery movement?

Kind regards,


  • Hi,

    This jittering is caused by the current camera tracking logic, it's running on Render() instead of LateUpdate(), a fix is already on it's way. So, there's nothing wrong with the movement, input or any Fusion related logic.

  • @Isaac_Augusto Hello, I am experiencing the same thing. I have the latest fusion but still Interpolation data source "Auto" causes jittery movement.

    Mine is like this

    Interpolation data source : Auto (jump and movement is a little bit jittery.)

    Interpolation data source : No Interpolation (the jump and overall movement is smooth)

  • I fixed the jitteriness by removing the collider in the Interp. data source.
