Whats the Snap to Seed Pattern feature?
Since version 1.1.9 PixPlant includes a new setting that automatically snaps the Seed Scale settings to the nearest best value for tiling. This is important so that the elements in the generated texture spatially “meet” at the image boundaries, so as to obtain a good tiling. If the Scale Lock button at the right of the Seed Scale sliders is set, both width and height will snap – if you prefer, unset Scale Lock and then change the sliders individually.
