Help Index was outside the bounds of the array

Indeed, it was a bug. Thanks you both for finding and reporting it.

Change lines 153-162 of ObiSkinnedCloth.cs with this:

Code:

int solverIndex = batch.particleIndices[i];
int actorIndex = solver.particleToActor[solverIndex].indexInActor;

batch.skinPoints[i] = skinToSolver.MultiplyPoint3x4(sortedPoints[actorIndex]);
batch.skinNormals[i] = skinToSolver.MultiplyVector(sortedNormals[actorIndex]);

// Rigidly transform particles with zero skin radius and zero compliance:
if (Mathf.Approximately(batch.skinRadiiBackstop[i * 3], 0) & Mathf.Approximately(batch.skinCompliance[i], 0))
{
     solver.invMasses[solverIndex] = 0;
     solver.positions[solverIndex] = batch.skinPoints[i];
}

That should fix it. I'm attaching the entire corrected file for convenience.

Let me know how it goes.
