Stochastic Texture Tiling or random texture tiling (improved the tiling layers)
Color variation to each tile (controlled)
(the make it tile advanced options)
(the tile options)
PRB textures are great but the size sometimes does not help specially for large surface objects, where the result is not acceptable because of the tailing pattern.
The tiling and Make advanced tiling should be one full layers that groups all tiling options, the software already uses a lot of different tiling parameters for other purposes, that im sure can be used and refine to achieve a better tiling process to generate bigger textures for large surfaces this will be a great addition.
