I've had the pleasure to have worked on Avatar: Frontiers of Pandora as a Prop / Environment artist and here is one of the many things I created!
I was responsible for creating an ivy spline that would be used to show overgrowth in abandoned landmarks. This ivy spline was the result of a technical R&D endeavor in which the goal was to create a spline that randomly generated ivy in a proper manner across the length of the spline, no matter how long it extended. Collaborating with tech artists Daniella Thomasson and Kunal Luthra I was able to achieve this final result.
