Hi everyone,
This is my first post on here… I hope you’ll go easy on me. 
So 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. In fact, the camera will only ever see ‘inside’ the bowl, and the peaks surrounding it.)
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–colour and bump at the very least–than the flat areas. The lowest parts of the bowl, where the water meets the rock need to be darker since they are “wet”… A color map is the way to do this, I know, but how do I vertex paint/airbrush that in?
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. I was also thinking that maybe I didn’t use an appropriate method for making this model, given what I am trying to do with it. I tried a couple of other ways, but none proved any better… Spline patching was bad idea. Using Magnet to deform stuff looked OK to start, 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 sheer drops, never came out. Can anyone think of anything else for me to try?
