Shaders day 2

I didn't have a lot of time today to work on shaders. Today I learned about how to implement lighting. Catlike coding goes over the blin-phong lighting model as well as a physically based model. Some of the topics that were covered were specular, metallic, and smoothness. Making sure that the outputs for the albedo, specular, and more are less than 1 so they don't overpower other parts of the shader gives the shader a more realistic feel. There are more colors and directions that go into making the final color than I realized. Attached is an example of what I have so far.
