This article explores an advanced hybrid workflow combining photogrammetry and procedural generation to create highly detailed, seamless PBR textures for use in games, archviz, and VFX. It covers the acquisition of high-quality base data through photogrammetry, including best practices for capturing and processing real-world surface details. The piece then delves into procedural techniques to enhance and expand these scanned textures with micro-variation, pattern generation, and surface detail augmentations that maintain material realism while optimizing for real-time engines like Unreal and Blender. Readers will learn how to create complete PBR maps such as albedo, normal, roughness, height, metallic, and ambient occlusion from this hybrid approach, manage UDIM workflows for large assets, and troubleshoot common issues like seams, tiling artifacts, and calibration mismatches.
