This one is pretty special as I really wanted to learn how to do plants.
To push the project further, I made some custom HSL shader in UE4 (color variation) and I painted vertex color on the meshes (wind animation).
I firstly created the leafs textures in Designer and then created an Atlas where all the variation of leafs would be placed.
I composed my plants in 3dsmax after cutting out the texture.
I finally integrated it in UE4 and imported a custom vertex color texture to allows the top of the plants to move.
