If I'm not mistaken, KINGPIX is using Connary's Grazelands for MGSO which if I recall correctly he said he would be phasing out by the next MGSO full version update in order to be in line with Connary's wishes that his work not be included in any compilations.
I can't use them for UC: Nature, anyway. I've tried several times to get a hold of Connary but he hasn't ever replied to me and I rather doubt he'd give me permission to use his work anyway based on his stance on such things in the past.
I wouldn't even bother, he messed me up with a mod with over 60 cells done based on his textures after giving me the permission 2 days before his mental break, so if he didn't care about [censored] up someone that badly, he probably won't care about this either.
And I usually don't like compilations, but I gotta admit I like 90% of what you did there, aside from few bad matches, really nice work man! Hope to see other compilations of yours. :foodndrink:
Also, where the heck do you people find all those high res terrain textures, I never stumble upon any good ones <_<
