Horizon Based Ambient Occlusion (HBAO) is a post-processing image effect to use in order to add realism to your scenes. It helps to accentuate small surface details and reproduce light attenuation due to occlusion.

HBAO delivers more accurate AO compared to the other SSAO solutions available on the asset store, and this without any compromise on performances.

This algorithm is highly optimized to use minimal GPU time and offers the best quality to performance ratio.

With Color Bleeding feature. HBAO is Gaia extension ready.

HBAO is compatible with both forward and deferred rendering, and artifact-free with forwarding rendered SpeedTrees and foliage. Source code included in the package.
