Orsin I'm sorry but everything so far says we won't, at least in forseeable future (but with TK you never know)
I wish we had some sort of documentation, back in the testing stuff days I was only able to
1)create mesh in Max from heightmap
2)texture it
3)split into several pieces
4)import these into game and setup to show
but there were HUGE errors like bad rendering of faces (wrong normals showing through hills etc) terrible I mean terrible errors with the clipping near the "shores" regions and above all errors with terrain collision detections, some parts of the mesh, you could happily fly through
so given the lack of documentation and I think not so much interest from other modders in the area I decided to switch back to improving existing old format terrains
