This is a shot in the dark.
I'm aware of only one default replacement for bare walls in build mode. That's
this right here which replaces the flat gray with a numbered scale, for building purposes.
What I'd like is a replacement that makes bare walls look more like walls under construction.
Ideally, it would replace the flat gray with one of the Maxis plywood or sheetrock textures:
But anything that looked like walls under construction would be great. Perhaps someone has made one with logs or planks for historical reenactment sims? Fingers crossed that someone out there knows of something like this. :)
