SOLVED Im trying to create my first mod and i have a question

So, ive been wondering, you know how the official beamng cars have that white showroom background? and some mod cars have it too, how do i do that? is it like a map? if so where do i download it?

 

It's in the default game, just check "Include auxiliary debug content" in the bottom right corner and select the showroom map

 

could you maybe give me a screenshot as to where it is? i cant find it
