step 2: replaced the light sand texture with a darker dirt texture. still works well with tarsonis rocks (see third in front of main - maybe even more 3d-ish feeling there now.)
I can hardly see the sdifference in the texturing, but thats good I supose, as long as it's more probe friendly. There is less contrast int the last lighting pic, and I like the first best I think, unless the contrasts make the textures probe unfriendly again?
textures are the same in the last two steps. only lighting differs. There are two lighter and warmer and two darker and colder light setups. Personally I prefer the warm Monlyth lighting for a day situation and the first blueish light in the last post.
