Topic Description
Use usage hints to reduce draw calls and geometry regeneration Use usage hints to set how an element is used at runtime. Usage hints can reduce draw calls and avoid geometry regeneration.
Control textures of the dynamic atlas Use an atlas to reduce the number of batches broken by texture changes and achieve good performance.
Platform and mesh consideration Consider device capabilities and avoid meshThe main graphics primitive of Unity. Meshes make up a large part of your 3D worlds. Unity supports triangulated or Quadrangulated polygon meshes. Nurbs, Nurms, Subdiv surfaces must be converted to polygons. More info
