Mod hasn't been updated for 4 years, and it will never be updated,sadly. The author of this mod passed away several years ago.
Lots of BeamNGers saying it won't work.. This mods creator is Resting In Peace so if you want something like this then you'll have to use another version of the same idea? Try this, I have not tested it, If it's also broken then see above bar under where you login to BeamNG... See WIKI ? That can teach you things.. Read it... Try this mod.. https://www.beamng.com/resources/the-modular-destructible-building.8848/
just download normally and unpack. It spawns deconstructed so you have to build it yourself using the vehicle selector, but it always spawned like that.
