I bet more than anythign his mountain problem is related to entity order...and isn't there a reordering tool specificaly for reordering mountains from top left to bottom right or something?

I'm still a CC3 user, though a lot of the amazing work I've seen done in graphics apps here is turning me otherwise. I don't believe in touting one program over another really though because its all a matter of what you're comfortable with. I spend a lot of time over at the CGTalk forums, and I've learned that software choice is NOT a factor in artist capability.
