I've had a hunt around the forums and couldn't see anything related to this, but I was wondering if it was possible to be able to handle the UV parameters. The idea being that you could make a nice single polyvectory and apply the texture multiple times to it. Imagine I wanted to draw an area of grass, at the moment I would need to render say 30 tiles to cover the screen. Wouldn't it be nice to render 1 polyvector and just change the UV parameter to repeat the texture 15 times on the x axis, and 15 times on the y axis. Even better would then be the option to set the UV offsets. This would then allow us to scroll the texture on polyvector.
I can see a lot of practical uses for something this.
