Help Update "lag" between cloth and particle attachment target

[josemendez]

Dear Obi Team,

I made a flag which can be picked up with a handle in VR.
hierarchy is as follows:

handle
solver
- cloth

The handle is connected via particle attachment to the cloth.
When moving the handle in VR (grabbed) then the cloth lags behing.

I read other postings concerning lag but they were related to Pin constraints.
Solver interpolation is disabled.
I tried some of the Obi Updater Components but was not successful...

How can i minimise this lag, oder even prevent it? It really kills the immersion :-(

Cheers,
Christian

Make sure your move the handle before simulation kicks in each frame. Most of the time(*) this means doing it in FixedUpdate(), before the solver starts. If you don't you'll experience a 1-frame delay.

(*)Depends on what updater you're using, or if you're manually updating the solver, where you're doing so. Most commonly you'd use a ObiFixedUpdater(). So, you'd want to move your handle in FixedUpdate, before the updater does its thing. Easiest way is to subscribe to the solver.OnBeginStep event.
