Thank you!
I would be remiss if I didn't give some credit to Ulco Glimmerveen (Dune) for the basis of the outcrop in the second image. Ulco shared a few files with me some time ago and I have exploited them shamelessly on several occasions. The terrain in the first image is a combination of two World Machine files merged and modified in TG. Both images are 'Path Traced' and the difference is fairly subtle and probably worth the additional render times. I've had a question about the cloud formation in "Something in the Wind" on PM, and I'll post the .tgc in 'Sharing' in the next few days; it's a basic Easy Cloud, but sun angle and some other factors play into it's final look.
