As I see it, you're using the Pegasus project as a foundation, correct? I agree, but I had so many issues with the IDMap workflow that I gave up on it. The HDA creators don't maintain their HDAs, and because of that, the IDMap workflow became too frustrating for me. That said, I agree with you, although I prefer Gaea as the first step. Then Houdini, and finally Unreal. Its more about combining tools.

I use World creator
World creator is also good for terrain. But you should give Houdini a shot

It has really changed my WorkFlow
