So i decided to get rid of the grid system as i realized it will be a failure, instead i decided to use the spline tool to create my roads, its way faster and easier to do it that way. I've put my texture onto the road mesh which was already within the engine and used it for the spline tool, I am really happy with the outcome just need to fix a couple of things, also 3ds max on my computer is broken and whenever i access it it just kicks me out.
