UE5 Cloth Simulation: Game-Ready Dynamic Jacket Rig Workflow
AI does the boring 80% in minutes — every part of this character arrived as a finished-looking 3D mesh. But under that surface the polygons are an irregular mass of dense triangles. The last 20% of craft makes it game-ready, and retopology is the heaviest piece of it: the most labor-intensive step in the entire production. Skip it and nothing downstream works: weight painting has no edge loops to follow, joints collapse when the character bends, and the mesh is far too heavy for a game engine anyway.
