Within 2D games, Unity allows the importation of sprites and an advanced 2D world renderer. With regard to 3D games, Unity allows specification of texture compression, mipmaps, and resolution settings for each platform that the game engine supports and provides support for bump mapping, reflection mapping, parallax mapping, screen-space ambient occlusion (SSAO), dynamic shadows using shadow maps, render-to-texture, and full-screen post-processing effects.

The transmittance term in our shading Equation (3) is computed at run time rather than using a shadow map in order to reduce memory occupancy. is the Henyey-Greenstein phase function for in-scatter and out-scatter directions. The lighting effect is summed over all light sources and their incident radiance . We integrate the shadow ray from sample position to end position . Users can also adjust the maximum proportion of the shadow ray. When the reach of the shadow ray is relatively small, the rendering method is equivalent to local ambient occlusion technique with one sampled direction (Hernell et al. 2010).
