Here's some realtime stylized trees and plants I created for an unannounced/cancelled indie game project in 2018.
Base meshes were created in Blender then sculpted in Zbrush. Bakes and materials were made in Substance Painter and then imported into Unreal Engine. I kept a relatively high tri-count since we used a diablo-like camera and couldn't see a lot of them at once. Leaves were created in Blender and then baked in Substance Painter. Leaves shaders were created in Unreal Engine with a custom rim solution and the use of a fuzzy node.
