    With Instant Impostors, users can automatically convert any mesh into an optimized low-poly impostor, massively increasing performance in large-scale scenes. Using advanced shader-based rendering, the impostors display a detailed representation of the original mesh, utilizing 3D parallax, self shadowing, and translucency to further replicate the detail of the original object.
