The needles are comprised of sets of rectangles perpendicular to each other, and are mapped for the accompanying needle textures which are included. Different shades can easily be achieved by altering the RGB/brightness of the 3 simple needle maps included. All objects are named appropriately, and a texture map is included for the unwrapped trunk. For smaller branches use a procedural map with colors similar to the trunk. I know the poly count is high, but required for a realistic tree. Other realistic pines available; search for 'pine tree.'
