A customizable shader for soft and painterly stylized trees.
Made for the Unity Built-in Render Pipeline (BiRP) and Universal Render Pipeline (URP).
This shader was inspired by (and uses the leaf textures from) this GeometryNodes asset for Blender.
ToonTree uses a very simple Lambert lighting model, which means it only supports the main directional light at the moment. Since it's an unlit shader, it also doesn't have self-shadows (yet).
This still allows for very stylized and colorful lighting that is highly customizable and responds to sunlight.
Colors are independently adjustable for specific lighting, color palettes or seasons.
Highlights and Shadows can also be adjusted for more stylization.
-
Softness - how soft or sharp the edge of highlights/shadows are
-
Size - how big highlights or shadows are.
Some nice color palettes for stylized trees:
basecolor highlight shadow
#339D67 #5AC452 #0D5B7D - original palette
#9D3D33 #FFA34E #6A1B34 - red autumn palette
Supports different alpha textures for leaves. Examples for textures can be found here
This is my very first written shader but I tried to structure it well and comment most important things.
If you find any issues in my shader code or graph, open an issue or pull request about it.
Either wait until I decide to implement them, or do it yourself!
Features (currently) missing from the shader are:
- wind and sway
- colored lighting
- extra light support
- snow coverage
