Volumetric Ambient Occlusion Unity Plugin v1.4 has been released + DEMO
Another new version of VAO (our SSAO plugin) has been released! We have both added new features and optimized the existing ones. New demo has also been released.
Get full version at Unity Asset Store
What’s new in v1.4
- Color bleed mode
- Presence option to make effect more pronounced without increasing radius (which means no additional performance hit)
- Speed Boost experimental optimization feature
- More Quality options
About VAO
VAO works by approximating amount of light that can reach given pixel taking volume of surrounding geometry into account. We have developed fast approximation algorithm and use fine-tuned random samples sets to calculate it in real time. Ambient occlusion will add depth and realism to your scenes.
Our algorithm works in screen space (using only normals and depth values readily available in G-Buffer). Therefore, there is no performance hit when using more complicated meshes (more polygons) and it makes use of bump textures automatically. It is also fully dynamic - there is no need for pre-calculating specific scenes and it works with both static and moving objects.
In the newest version, we added color bleed option. This means that on top of shadows the surfaces now cast their color onto their surroundings. We also
See documentation here and forum here.

Performance tips
- Judge the quality by the final image, not AO only.
- For the best results set Radius so the shadow created by the effect is around 10-20cm (4-8in).
- To make AO effect more pronounced increase Presence and Power settings before increasing Radius.
- Use appropriate number of samples (Quality setting) - high enough to hide aliasing.
- Consider using Downsampling at high screen resoltions.
- Use Speed Boost feature (currently experimental.)
