Setting this to 0 allows to ship a game with more optimized shaders as someditor and development features are not longer compiled into the shaders Note: This should be done when shipping but it's not done automatically yet (feature need to matur and shaders will compile slower as shader caching from development isn't shared)Cannot be changed at runtime - can be put into BaseEngine.in 0: off, shader can run a bit faste 1: on (Default)
