• Fixed a deadlock with vertex displacement.

11.0.112 - 2014-10-07

• Fixed some filtering issues with raytraced displacement.

11.0.46 - 2014-03-06

• The opacity() method of shaders is no longer systematically run before surface(). This may require updating some hand coded shaders to either include the opacity code in surface() or make an explicit call to opacity().
