Around the beginning of the first COVID-19-related lockdown in Austria, I was confronted with the problem of keeping my motivation up. From 2012–2016, my main tool for creating several Wolfram Demonstrations in 3D was Mathematica. Now, in addition to the Wolfram Language, Blender offered the possibility for physically based rendering (PBR) and high dynamic range (HDR) lighting and rendering. So I decided to go forward with 4K videos from animations done in Blender.
