  • Question re UVW Randomizer

    For U and V offset Variation you can enter in min and max values. Do those offset values represent a % of the size of the map being offset or does the offset value represent some amount of the scene units (feet, meters, etc) or......?

    I understand how to set up the UVW randomizer. I gt that you must choose "by element" or "by name" or etc depending on the geometry used and etc. I think I get the Stochastic tiling.

    What I don't get is how the U and V offset values work. I know the step value is also important to the U and V offset. I have searched for good tutorials on how to use the UVW randomizer, especially for the u and V offset. I'm not finding much. I'd like to learn, for starters, how to use that for a wood texture applied to a bunch of cabinets or maybe wood beams. Same for tile and natural stone like marble, limestone, etc.

    This is the best thing I have found so far. It is for Corona but I think pretty applicable to Vray. It moves along very fast and I need to watch it again a few times to hopefully get it. Anyone know if any better explanation/tutorial for how to understand and control the very powerful and valuable UVW randommizer ?

      You can see how it works for one example in the docs https://docs.chaosgroup.com/display/...omizer-example
      It's also great if you want to break up what would otherwise be noticeable tiling on, say, asphalt or marble or similar

      For your example of wooden cabinets it wouldn't really work so well. You'd be better off using the UVW randomizer script to literally apply a random unique UVW modifier to whatever
      geometry you are dealing with. Great for fences, rails, cladding....where you have loads of panels and only the one map to use.
