Now that you’re familiar with the principles of physically based shading and how to ensure your BRDF implementation respects them, we can explore some of the BRDFs described in past papers.

You can invent your own from scratch, for example by deriving them from the microfacet theory model, or you can choose one out of the many BRDFs that have been described in graphics papers in the past.

BRDF Explorer

Since implementing a BRDF in Unity is a fair bit of work, to explore the many available BRDFs we’re going to use a different tool. This tool ...
