Help Adding pin constraints to a rope at runtime

[Gieve]

Exact same problem as OP.

Change this:

Code:

ObiPinConstraintBatch batch = pins.GetFirstBatch()[0] as ObiPinConstraintBatch;

to this:

Code:

ObiPinConstraintBatch batch = pins.GetFirstBatch() as ObiPinConstraintBatch;

Sorry I had already done that, just reverted it to remind myself of the error forgot to re-set it before copying the code.

Sorry for the confusion, the error "NullReferenceException: Object reference not set to an instance of an object" occurs with the code set as in your suggestion.
