The stylized tree shader project files from this video tutorial:
Project Blog Post:
"Learn a bunch of stuff about shading by making an excessively fancy tree leaf shader! Our subject is a spherical tree that will get custom radial Normals, mixed colors, and much more. We'll try to keep it compatible with Instancing and Scattering, but this tutorial isn't about those.
You do not need a huge amount of shader node knowledge to follow along, but this is probably above absolute beginners. There's lots of good foundational information like how to balance lights, map ranges, and mix colors. Also advanced stuff like lifting Normal Map details and applying them to Custom Normals via Surface Gradients!"
