I created this tree asset entirely procedural, using Houdini and Unity. The Leaves and the branches move independently via vertex color ramps in the red and green channel, while the blue channel is used as a mask to define bark and leaves. The roots adapt to the ground, as seen in the last images. Instead of using an L-System, I used different copy to point iterations to get the shape. This gives me a more random look.
