Fourth test of my new PBR lighting pipeline.
IBL probes are solved in realtime on the GPU.
I'm now moving on to testing this pipeline with animated characters and skin shading.
I plan on releasing an open source tool based on this work in the near future that will allow a user to prototype and bake diffuse irradiance and specular mip chain IBLs using a custom BRDF.
Many thanks to Andrew Maximov for releasing his pistol asset.
It is always incredibly helpful to have well tuned assets to work with when implementing this stuff.
