I’d done quite a bit of (albeit amateurish) 3D modelling for another 3D project in the past, and my go-to tool was Blender (version 2.79).
I thought for Digger Doggy, Blender might be a good tool to re-acquaint myself with, at least for decent-enough looking “programmer art”.
Even though it’s been over a year since I did anything with Blender, and decided to leap into the new Blender 2.81 (a huuuuuge upgrade), I’m happy with the results.
