Colorado - The Spanish (Latin) translation is Color 'Red' - so called many years ago when the early Spanish explorers saw the Grand Canyon and its river the first time.
Thanks to Phil ('Mr_Lamppost') for his 'Red Sky' .tgd file which can be found at the Planetside Forum in the Cloud Library.
Additionally, thanks to Walli for the Pine Trees and The Noble One tree which are available at the Planetside Forum. Also, Walli's Dry Shrubs are available at NWDA.
The trees were set as individual objects; and, the shrubs set as a population using the Painted Shader. Both the clouds and the Fractal terrain were re-seeded numerous times to achieve the results you see in the image.
Enjoy.
Nice look to this one!
