Random Weights on Polygon Parts
@Funk over on the MODO slack came up with this cool schematic idea of using a falloff operator to assign random weights to polygon parts (poly islands) and use that for random variation in Octane rendering. You can use this technique for all kinds of stuff - randomizing deformation on polygon islands (parts), etc.
Procedural Random Weights on Polygon Parts - you can use them for anything, in this case we're doing random shading in Octane on each Polygon Part.
