i made an extremely compact coaster and there isnt much room for supports, lots of places were the track passes under another section of track. im just wondering what would be the best way to tackle the supports.

Just connect a bunch of the supports together.

I agree with Ardy.
Additional, helpful could be to look at Screens of "real" coasters to get some inspiration how they did that in real.

"Poltergeist" @ Six Flags Fiesta Texas is an good example for compact build coaster
