Help How to update particles immediately after activating ObiRope Component

[asimofu_ok]

I made a method to modify particle positions and activate actor.
It is like this.

Code:

obiRope.enabled = true;
for(int i=0; i< obiRope.solver.positions.Count; i++)
    obiRope.solver.positions[obiRope.solverIndices[i]] = targetPositions[i];

However, it displays particles that are before deactivating only at one frame immediately after executing this.

I tried some update or rebuild methods for ObiRope and ObiSolver.
But I didn't find method to force update particles.
Is there a way to solve this?
