This tool was made for a personal project, it uses modular bits of a building to assemble it into one whole building.
It has quite a few parameters to play with and allows a variety of instantly modelled buildings with a few modular buildings asset packs.
None of the modelling and texturing was done by me, credit goes to Neo-baroque Modular Building Asset Pack on Quixel Bridge and to KnightFallows on Sketchfab for the fire escape stairs.
Showcase of the tool by laying out a few buildings.
Changing the building's dimensions .
Tweeking the doors at the base of the building and changing up the stairs.
Adjusting the wall patterns and the walls' randomness.
