Here is the .tgd - and also a clip file - from this thread -
http://forums.planetside.co.uk/index.php?topic=8622.0I thought I'd include a node shot and a few comments, just so you can hit the ground running.
The main motivation for this file was to create a rock surface with displacements at a range of scales, plus convincing colours. To do this, I used two powerful tools that are already available: glen5700's Fractalized Voronoi (not visible because it's HUGE!) and Volker Harun's OneforAll; plus the great spirit of sharing on these boards that has given me some small clue on how to use redirect and tune power fractals.
The main places to go for tuning:
- Displacement tab of the three power fractals feeding into the
Redirect - value currently set at 5, but I've had reasonable results pushing it as far as 15.
-
over all displacement (not visible - it's on the bottom left of the
Voronoi Fractalized) Set at 1, but can be pushed further - also, I've disabled two of the octaves that could be reactivated if desired
-
Roughen surface Displacement tab multiplier set at 2 can be pushed further (driven by OneforAll). Also, if you want a smoother look, switch on the Intersect Underlying in Effects, with Smoothing set to 0.85
There's also two fake stone shaders that are currently disabled. The first (displ-medium) produces negative fake stones, i.e. small holes, which is an effect that might not be to everyone's taste - I didn't have time to try this, but I suspect using a painted shader to apply this selectively might be the best idea. The second (with the attached Reflective shader) produces the specular highlights that give a slightly shiny look - this increases render time significantly.
Have fun!
