Single Status Update
My workflow is basically running from a chain of disasters, eventually trying to seek shelter in former disasters. It's not ideal - it's just my life.
When I abandoned my first map, it was out of a typical mental breakdown, and so I returned to find a skybox void where the kitchen door should have been (due to a misplaced visportal) and two overlapping brushes Z-fighting on the kitchen floor.
I've now cleaned up the last bit of mess, by cleanly separating every floor into its own layer. Now I can finally work on each floor in peace.
...not that I really needed to. Once you get skilled enough, the orthographic messes, well, I'll let this video speak for itself:
I also opened up the west wing of the ground floor today. I still need to create the furniture, but now the complex part is done. Felt I had to expand the whole building a bit, which was a little scary. I made the whole house pretty cramped.
