Custom BRDFs in deferred shading/lighting in Unity

So, https://twitter.com/sunjammer/status/569925239989256192 and https://twitter.com/sunjammer/status/569983534368206848

Now, depends on whether you want custom BRDF in deferred on 1) all your objects (easy) or 2) only some of your objects (harder).

1. change BRDF for everything

That's fairly easy. The actual object shaders more or less just fill the g-buffer (and in Unity 4.x deferred lighting, combine textures with the lighting buffer in the final pass). The actual BRDF is in the "light shader". Start by copying the built-in light shader (4.x deferred lighting: Internal-PrePassLighting.shader; 5.0 deferred shading: Internal-DeferredShading.shader) into your project. In 4.x, put it into Resources folder so it's included into the build; in 5.0 point Unity to use that shader under Project Settings -> Graphics.

Change the shader to do different BRDF.

Code running pack! two property drawing scripts that make it super easy to trigger code via buttons in the inspector, and get feedback! [TestButton] draws you little buttons that call a method on your MonoBehaviour, and [ProgressBar] give you a great way to show feedback from long running methods. These are *super* helpful for things like proced…

Run stuff in the editor with all the convenience of co-routines! Add a status UI super easily to see readouts what your long running code is actually doing! nice~ There is a short API demo at the top of the class. This is a prefect companion for my inspector buttons https://gist.github.com/LotteMakesStuff/dd785ff49b2a5048bb60333a6a125187
