In this demo, we’re breaking down the logic of lighting using a simple building structure. Instead of jumping straight to the highlights, the process starts by establishing clear local values and diffuse sky light. Once that foundation is set, we bring in the key light, bounce light, and specularity to make the form pop.

It’s a great way to see how layering these elements step-by-step keeps your painting from looking flat. You’ll see how to handle soft shadows versus cast shadows and how to use subtle temperature shifts to make the materials feel more realistic.
