This tutorial demonstrates the workflow for creating optimized, game-ready rubble piles using Blender and Unreal Engine. It covers using particles and physics to simulate naturally falling debris to build a high-poly asset with multiple materials. The guide then explains how to convert this high-poly setup into a low-poly mesh with a single baked PBR texture set, including albedo, roughness, metallic, and normal maps. Finally, it outlines the process of importing the mesh into Unreal Engine, complete with techniques for blending the asset naturally into an environment.
