This project for me came from a desire to recreate a path I used to walk repeatedly on many vacations. I gathered up photo references from my past, and illustrated the above general concept.
I created high poly sculpts in Zbrush to eventually create foliage cards.
It was important to me to create plants that were geographically accurate.
Using Substance Designer, I created various textures.
Took a game art environment class with the super insightful Jeremy Huxley via his CGMA course.
I've been brushing this project up since then, and have definitely built on it. I plan to return to this project.
