D&ad; Development, creating a road texture

First of all find yourself a nice asphalt texture, open in Photoshop and add your road markings by using the marquee tool and fill white lines for the centre of the road with two thinner parallel yellow ones at each side. Create curved yellow marks for the edge where this road will join another. Duplicate to make a full road network not forgetting to create an alpha channel to make sure the invisible bits won't be seen when assigned to a material in maya.
