**MiniEngineAO** is a SSAO image effect for Unity that was originally developed

by Team Minigraph at Microsoft for their [MiniEngine] library.

MiniEngineAO has several advantages compared to other SSAO implementations --

smooth results, good temporal characteristics, optimized for GPU compute. The

most significant advantage may be speed. It's heavily optimized with the

compute shader features, especially with the local memory (TGSM/LDS) use, so

that it manages to avoid major bottlenecks that can be found in traditional

SSAO implementations.

The original design of MiniEngineAO can be explained as a combination of two

known SSAO methods: [Volumetric Obscurance] and [Multi-Scale Ambient Occlusion].

It's well-tailored to have the advantages of both these methods.

System Requirements

-------------------

- Unity 2017.1.0 or later.

- [Compute shader] and [texture array] support.

Although Metal (macOS/iOS) is thought to fulfill the requirements, it doesn't

work due to a texture array issue ([case 926975]). This issue has been already

fixed in the development branch, so it'll be resolved in a near future release.

Installation

------------

Download one of the unitypackage files from the [Releases] page and import it

to a project.
