Creating Utility Textures for Trees – Normals, Roughness & SSS Explained

Описание: In this episode, I break down the essential utility textures needed to make a tree asset game-ready.
I show how I generate a normal map from a high-resolution mesh using RealityScan, how I extract a roughness texture from the diffuse, and how I create a subsurface scattering (SSS) mask for mosses and grasses.
I also explain how and why I combine multiple utility textures into a single RGB texture, keeping the asset optimized and ready for Unreal Engine. All texture processing and packing is done in Photoshop.

About the Series
This video is part of my ongoing forest environment series, where I document the full workflow of creating realistic trees — from photogrammetry and sculpting to final optimized assets for Unreal Engine.
