Low-Poly Model
Game-ready mesh
Also known as: Lo-poly · Game-ready mesh · Low res model
Definition
A low-poly model is the game-ready version of an asset with a polygon count tuned for real-time rendering — typically thousands of triangles, not millions. The low-poly preserves the silhouette of the original sculpt but relies on baked normal maps to convey surface detail. Polycount budgets depend on platform: mobile budgets stay under 10k tris per character, PC and console hero characters can run 30k–100k.
In production
The low-poly is built either by retopologizing the high-poly sculpt in Maya or Blender, or by using automated decimation tools like Simplygon or UE5's Nanite mesh reduction, though Nanite changes the calculus since it can render far denser meshes directly and reduces the pressure to hand-optimize every prop. A low-poly must still carry clean UVs, since it's the mesh that receives the baked normal, AO, and curvature maps — stretched or overlapping UVs on the low-poly cause visible seams or doubled detail once textures are applied. A common beginner mistake is optimizing silhouette-affecting geometry too aggressively (rounding off a helmet's brim to save fifty triangles, for example) while leaving unseen interior geometry untouched, when the opposite prioritization saves far more render cost for the same visual impact.
