Was learning some lighting tips from a Minecraft artist that bad? Probably somewhat, but even if you learned nothing, I got you to read this series :D
There’s many other resources on learning how to master lighting, this is just one. I personally recommend Andrew Price’s series on lighting, as he goes in depth about more Blender specifics. In addition, Pixar’s Khan Academy course is also an amazing course on what I like to call “Light Theory”.
I hope this “guide” will encourage you to go on a journey to master a skill that’s commonly forgotten about.
Cya!
