Rocks - Cliffs
When I was hired to work on Paw Patrol, one of the first things I was asked to do was improve the look of the rocks.
Every so often I worked on improving the quality of the rocks until I designed the look of the cliff on the left. This cliff ended up being reused on dozens of episodes.
In general we reused modular rock geometry, but for closeup acting areas we sculpted higher resolution unique rock geo which holds up better on screen. They were still created using pre-existing rock geo as a base.
