Need help importing big models

I’ve been trying to import my airbase model into roblox but no matter what I do, the imports always come up small and the same size as a default baseplate (2048 x 2048). I’ve broken the airbase model into smaller sections and pieces.


You could divide the airbase into smaller pieces and then import them, and then stick them back together.
I had that problem multiple times and the only thing I could do is just divide the map. I’m sure there is other ways but that what I could think of.
