After my flop at attempting Displacement Maps, I tried to sculpt the entire mountain range in Mudbox.
This was more the desired effect I was going for. The mountains were strong and tall, with all the little craggy details needed to make them look huge. The crevice also worked nicely.
The only downside the the phenomenal polycount reaching way into the millions.
To fix this issue, I brought the model into Maya and started working on the final stage.
