What's the best option for making my own terrain that I can use in Daz?  I have an idea for a desert scene but don't have a desert, so I attempted to make something in Bryce and failed miserably.  I'm trying to learn that program but it hurts my brain it's so user unfriendly (compared to Daz). 

I grabbed Terragen and it makes some nice images that can be used as a background, but no way to place it in Daz.

Vue looks amazing, btu I have no idea what the learning curve is on that. 

Suggestions?
