MiniEngineAO

MiniEngineAO

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
