Screen Space Ambient Occlusion - Custom Lighting Models - Episode 9

Описание: In this shader tutorial, I show how to write the code required to bring screen space ambient occlusion into our custom lighting model in Unity. Once available we can use it in the traditional way to darken the ambient - but we can also use it in other, unique ways to get just the look we're looking for.

Here's the code for the Custom Function node:

#if defined(_SCREEN_SPACE_OCCLUSION) && !defined(_SURFACE_TYPE_TRANSPARENT) && !defined(SHADERGRAPH_PREVIEW)
float ssao = saturate(SampleAmbientOcclusion(ScreenPos) + (1.0 - _AmbientOcclusionParam.x));
IndirectAO = ssao;
DirectAO = lerp(1.0, ssao, _AmbientOcclusionParam.w);
#else
DirectAO = 1.0;
IndirectAO = 1.0;
#endif
