Materials with Normal opacity mode are now calculated with the Stochastic opacity mode. Stochastic is now the default mode and replaces Normal in old scenes, as it gives the same results but is faster. The Clip mode calculates faster and gives better and more accurate results when there is only pure white and pure black in the opacity map.
