Unreal Shader – Vegetation by Michael Gerard

Welcome to the Unreal Shader series!

In this course, I will guide you step by step on how to create a Vegetation Shader!

For vegetation models, the shader is more critical than any other model type. Learn to create the perfect shader for your trees, saplings, bushes, small plants, and grass!

Compatible with Megascans 3D plants and Speedtree assets.

What you will learn:

• Two main shaders (the first one for Bark/Foliage assets and the second one for ground foliage)
• Attribute Parameters (Color, normal, roughness, specular, AO intensities)
• Subsurface Scattering (with custom color & intensity controls)
• Billboard logic (Speedtree Only)
• Two different winds (a wavy one for non-Speedtree assets and the native Speedtree wind – .st9 format not supported)
• RVT Blending (make the perfect transition between the terrain and the foliage)
