What is the CoronaUvwRandomizer map?


The Corona UVW Randomizer map allows applying random offset / rotation / scale to textures and procedural maps assigned to different objects. The way it works is similar to the Corona MultiMap. For example, you can randomize a wood texture applied to a set of planks so that each has a different look in your final render.


Note: the effect of the UVW Randomizer map will not be visible in the viewport preview. 




Examples


When applying a single material to multiple duplicated objects, an obvious pattern may appear, which makes the rendering unrealistic:



The CoronaUvwRanzomier map can be used to quickly fix this and randomize the transforms of the distributed texture:
