actually, and I'm probably disclosing this a little too early, the entire landscape is part of a proof of concept for a new type of NWDA product.
In a nutshell the idea to produce a whole heightfield-based landscape, with interesting terrain features and lots of possible great POV's, and procedurally enhanced in TG2, so that the finished product will have some brilliant small-scale detail everywhere, already out-of-the-box.
The beauty (and the challenge) is to use relatively low-resolution heightfields, in order to be nice to memory consumption, and just about the right procedural enhancements to make this look like a vast and real landscape.
That being said, I'm only at the beginning of investigating the possibilities for such a potential NWDA product type. Martin has another example of this concept cooking. He'll probably post a render today. You'll be amazed, this much I can already tell you!
So far the product idea seems possible and the results are encouraging, but no promises yet this will happen.
@eoinarmstrong
yes, all the flow, wear and deposit maps come into play. The maps will be embedded in the to-be-shipped scene, so that users can switch them on and off, or re-use them for their own modifications.
Cheers,
Frank
