Bug / Crash Weird movement of obi cloth

[Richard]

Use local space simulation. That would allow you to scale the cloth simulation arbitrarily:

To select particles near a given zone at runtime, either use trigger colliders:

or just calculate the particle distance to a given point and then select those close enough. The last example in the page does pretty much this.
