Chapter 8 "Highlands" for the Master 3D Environments in Blender course is now finished, including the compositing breakdown.
The "Highlands" chapter features a very common approach to making your environments - taking pre-made displacement and texture maps, and using them to displace your geometry in Blender. No external tools needed, you can follow along with the files attached to the lessons. Works fine with EEVEE too!
In the new lesson 07, we will bring our rendered elements together using Blender's compositor. You will also learn how to mask layers using the Depth pass, a pretty handy skill for all compositing needs.
