As a result, by the end of that chapter, we had a simple unlit URP shader with a base color and a main texture property.

This was a nice introduction to the topic, but of course, modern video games only rarely ship with this rough a shading level – while having all of your objects unlit could be a conscious artistic choice, it would ...
