I made a Blender addon to speed up worldbuilding.

It rotates the view to the same iso angles as the game for a quick preview.

It scales texture maps to an absolute size to eliminate guesswork.

It places library objects centered on the nearest grid tile. Tables, chairs, trash bins, houseplants, etc. The sinks and toilets have their origin offset so when it's centered, they're flush against the wall. Doors are an exception; the origin is at the hinge so I have to manually place them, but no big deal.

Maybe by the end of September we'll have decent textures, lighting, and furnishings throughout the game world. I might be putting the cart before the horse, but it's a psychological priority. Somehow it's just easier to do substantive gameplay work when the graphics aren't making my eyes bleed.
