Syntax
int32 ProjectionIterations
Remarks
RBAN: The number of projection iterations to run. The projection phase is a final pass over the constraints, applying a semi-physical correction to any joint errors remaining after the position and velocity solves. It can be very helpful to stabilize joint chains, but can cause issues with collision response. The projection magnitude can be controlled per-constraint in the constraint settings (assuming ProjectionIteration is not zero). This should be left as 1 in almost all cases.
