I’m happy to announce that our SSAL package will be released on the unity asset store soon.
Unity users will now have the ability to use realtime arealights in their applications by using our screen space implementation.
It supports all the goodness, such as deferred and forward rendering, correctly works together with the builtin unity materials, lights and shadows. And since it is rendered as image effect, it is decoupled from the geometric complexity of the rendered scene.
There is a preview version to play around with.
You can also follow the discussion on the unity forum.
