Why does it forget up this bad?
You're using a .map, therefore you're missing brushes, and evidently the textures didn't export correctly. Not to be rude, but actually
making the interior in Constructor is a better choice than making it in another program. Good luck though, Rainbow Road looks cool.
It's hilarious that an interior making program made specifically for the Torque Game Engine, doesn't even fully work at times
I hate its glitches, but it seems to work well enough with a re-install.
