Hooked up AO for the test character I barrowed, and fixed a few material issues. Visualization of AO affecting the fallback skylight on the left, and AO off on the right. The final image is with AO on both sides. I like to do a lot of material testing with a simple directional light shader like this as I can reload shaders via the HTTP interface in my engine, and it will back prop changes to materials as needed as well. Fast iteration!

Here's the in-game G-Buffer visualization, and note I only clear parts of my MRT as I stencil out non-deffered in the geometry pass. That's why you see the wavey lines on some visualizations.
