Ah okay, you mean "supports" with pillars.
To replace the original ingame supports against custom made ones all you need some CSO-Sets:
- Moby's Steel Jungle v1
- Moby's Steel Jungle v2 (optional, are the same pieces like in v1, only a bit thicker)
- CPcisco'sSteel Chaos (MSJ Addons) (it has all sloped angle versions, that aren't in Moby's Set)
- CPciscosB&M Footers (square footer, made for B&M Coasters, but can be used for other coasters, too)
- CoasterJoesB&M Connectors (optional, if you want to build B&M coasters)
For other types of coasters there are other Set's out there with specific "connectors" and "support" pieces.
Intamin:
- Coasterfreak90s MegacoasterAdditions
- CoasterJoesIntamin Turns
- CoasterJoesIntamin Supports
- CoasterJoesIntamin Footers
Arrow/Vekoma:
- SafariJsArrowPack
Woodies (GCI/CCI):
- BigBurger'sTimber 2.0
There are more set's that can be used to support some types of these coasters, i count only the most importent Sets here.
To delete the original support you have two options:
1) turn off the draw distance for supports in the options. So they will be invisible for our eyes.
or
2) use a "support killer" cso-piece, that is included for example in these sets:
- DasMatze Utilities
- Pumper-SteelWorx (Jcat's Steelworx)
Hope this helps,
