I started with making a texture on Photoshop using a cloud render and difference clouds. I then added another layer with a brown colour which I added a difference style to the layer, which surprisingly gave it a brown and blue colour.
After that I went back to my texture on Photoshop and added a new layer with a green/yellow colour. I then added noise to it by doing Filter > Noise > Add noise. I selected Gaussian and Monochromatic boxes and clicked ok. After I was satisfied with the layer style, I went to google and looked for a nice rock texture to my current texture. I played around with the layer styles I went and added one more layer with a brown colour, which I added the Overlay style to that.
Back to the environment on 3Ds Max, I added this new texture and added a target camera till I got a view which I liked the look of (The one in this picture above).
To finish things off I added a sphere over the plane. This is my sky box, I cut the bottom half away then flipped the sphere so the inside of it would show the image. I grabbed the image from Chris' iDrive and added the sky image to my sphere, making a sky dome.
Finally I added a volume fog by clicking on render > environments and played around at random until I got what I desired, at first for some reason I am not sure of, the entire environment kept going red, then green then back to red, then finally a foggy landscape, which isn't half bad in my opinion
Hopefully we'll be doing alot more on 3D environments in the future
