“` How to deal with Iterations: Substeps – More expensive, but gives a better solve – especially for higher stiffness values Constraint Iterations – Increase for higher stiffness value to control excessive deformations – great for cheaper solver at high resolutions Smoothing Iterations – smoothing ops, to smooth out errors of excessive deformations, or constraint errors Collision Iterations – Uses the Detangle sop – lower frequency iterations – complicated and time consuming – increase when collisions are fighting against constraints or other collisions However, its probably better to increase substeps and decrease constraint iterations for a more accurate solve – and to reduce load on the constraints – but is more expensive “`
