Horizon Based Ambient Occlusion (HBAO) is a post processing image effect to use in order to add realism to your scenes. It helps accentuating 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. Asset contains color bleeding and temporal filtering features. Gaia extension ready.
• Standard render pipeline, forward and deferred
• Universal Render Pipeline 7.1.8+ (Unity 2019.3+)
• High Definition Render Pipeline 7.1.8+ (Unity 2019.3+)
The effect is scalable in order to achieve the proper performances. Source code included in the package.
