Chapter 4 wraps up the course by explaining how to assetize 3D models, materials, worlds - i.e. Assets - to be part of Blender's Asset Browser. Once our Asset Library is established, we will create a few city blocks made by linking our assets into an "Assembly". Think digital LEGO's construction.
With our assembly complete, we will finalize it with lighting, a touch of post-processing treatment with Blender's compositor, then a conversion to a night time version.
If digital lighting is a brand new concept to you, consider watching the Fundamentals of Digital Lighting course first!
