Retopology for Unreal Engine: Expert Techniques Revealed - Puffin Foundation Resources
Learn retopology from a 15-year 3D modeling expert. Step-by-step Blender tutorial to rebuild meshes, optimize models, and get animation-ready results. Retopology (or retopo) is a step in the 3D modeling process where an object's polygonal mesh is modified or recreated to obtain a cleaner layout while maintaining nearly the same physical shape of the model.
Understanding the Context
[1][2] Owing to its complexity, retopology is currently a mostly manual process but tools exist to assist 3D artists with the workflow. Retopology is a process in 3D modeling in which the topology—the arrangement of vertices, edges, and faces in a 3D mesh—is optimized or reworked to create a more efficient 3D model. Retopology is the process of converting high-resolution models into something much smaller that can be used for animation. It can be a difficult process, but the basic idea is to create another mesh that simplifies the original HD asset.

Key Insights
The Retopology overlay of the 3D Viewport is useful here, as it lets you see the original mesh through the retopologized one and vice versa – without getting distracted by geometry on the other side as would be the case with X-Ray. You can use the Poly Build tool to quickly add, change, and remove faces. Learn how to retopologise 3D models with auto retopology tools. Complete guide to Remeshy techniques, retopology tools comparison, and professional workflow tips. Retopology is the art of refining 3D models, transforming them from high-resolution, messy sculpts into clean, animation-ready assets.
