In this video I show you how to install Probuilder and start creating levels.
You will learn about creating and editing objects, their vertices, edges or faces, extruding faces, snapping to grid and vertex snapping.
In the last part of the video you will learn about how to create a PBR material and assign it to a slot in the Probuilder Material editor so you can quickly navigate around your level adding different materials to it quickly and easily.
It's not a comprehensive tutorial but it's enough to get you started with the tool- the rest is down to you.
