At this point I need some tests, so here's the prototype of the building after a very short delay. Just download the zip and extract its contents into C:\users\<you>\BeamNG.drive\vehicles and you can spawn the building in the game. If it doesn't appear in your list, then double-check to make sure you extracted the zip correctly. This is really an attempt to see if the current state of the building is suitable before I add more parts and send it to the mod repository. I am already aware of a few things; the prop has more nodes and beams than any of the vanilla vehicles in the game, so it might draw more resources from your processing unit than usual. Some of the blocks stick through each other as well as in other vehicles or props. Not sure why, because this thing is col-tried from top to bottom. Also, the blocks on the front collapse on their own sometimes; resetting the building a couple of times tends to remedy that most of the time. Please send suggestions for this prototype if you have any to offer, and I will fix the most important issues before sending this prop to the repository (which I had promised will be on 17 June). After that, I'll trickle down the list to see what else can be done to improve the building. This is no longer available since the mod is already released.
