Guys, I have spent most of this afternoon playing with lighting and texturing, particularly in relation to the sun and sky. I rendered this test using Maya Software and I have managed to achieve the red effect that we were seeking.
I simply used lights, which I textured red, to create the lighting effect across the terrain. As for the sky itself; the sun is just a polygon sphere which I textured with a yellow Lambert, that I added a Glow Intensity to. The sky is a polygon plane that I textured with a Ramp.
Pretty simple really and not such a pain to render. Could you all take a look and suggest any improvements that you can think of?
