Hi everyone,
I’m trying to model a mountain bowl… here’s a screenshot of the model so far:
I created this with a single displacement map, over one object. The blue part is a separate “stand-in” polygon for water. (The orange is just a background colour, so we can see the model better, nothing to do with the final look of the project.)
My question has to do with surfacing/texturing… since obviously I don’t want to have the same texture across the entire object, how do I assign different surfaces to this model? For example, the high peaks will need a different surface than the flat areas, both in colour and in bump mapping.
I also need to paint at least one colour map, across the bottom of the canyon and bowl where the rock would be wet from the water, and hence, darker.
I already tried a few things, but didn’t get anywhere… 
I saved the transformed object from Layout, but selecting the correct polys once I loaded this into Modeler proved impossible. I also loaded the displacement map image into Modeler’s background but I simply couldn’t select the polys properly and the surfaces always ended up looking wrong.
Does anyone have any suggestions at all? I’ve been at this for a while, but I’m just not getting anywhere!
Thank you so much!
P.S. Did I not use a proper technique to create the model? In addition to the displacement map, I tried patching splines–bad idea. I also tried using Magnet to deform stuff, but after a few pushes and pulls, I couldn’t make sense of anything anymore. Finally, I tried using the Airbrush to “paint” rises with morph maps as height delimiters; this worked a little better, but I found that I didn’t quite have the control I needed for this, and some things, like the sheer drops, never came out.
