The first version tied the tiling settings of all textures to the Main Texture, as this is almost always the use case. But sometimes there might be the desire to have different textures that don't use the same tiling settings, so a toggle has been added (defaulted to on - linked) that can be unchecked to allow for independent tiling of the various textures.
Note - you must restart VAM to clear out the old shader after you've installed these new ones and deleted the old VAR.
