Failed to update position vector in some timing when using havok

playground: https://playground.babylonjs.com/#E9R16H#3

If I update position vector in after render call back or just sync, there will be some case that position can’t update. Now I get rid of this by setting body’s disableSync to true manually as a temp solution.

I believe the question occurs when getting bodyTransform in function syncTransform, but I cant debugger further.

cc @Cedric, but please be patient as most of the team members are currently on vacation.

disableSync to true means no update of mesh/scene graph transform from the physics. So the node translation/orientation is not overwritten by the physics.

Can you please try to make a small repo? I’m not sure to fully understand.

Sorry I dont make myself clear. In the origin pg (#1, in document), transforms’ positions are updated in onBeforeRenderObservable and works well. In my playground, I try to update transforms’ positions in onAfterRenderObservable or in sync and did not change anything else, but failed.

I was wondering if it is expected we can only update position of disableSync to true bodies in beforeRender but not afterRender nor in sync?

Sorry, for the delay. I’ll get back working on this asap.
