Here's a support tutorial that I started and never finished. I added some captions to help.
First, build your station and the lift hill
Then choose your colors
Open Gadget's (I think) Coaster Goodies, and find the support killer. This set is in the scenery section, not the walls section
Delete all the in-game supports
Here's what you should have
Now go to CoasterJoe's B&M Connectors
Add the connectors at the correct angles
Go to "Basic Version 1 Bottom" and recolor it to what you want your supports to be. I'm doing white
Place them underneath the connectors like this
Now open Moby's Steel Jungle
Add vertical supports on all of the connectors. You can go back and change them later if you need to
For the beginning, sometimes you can do a support like this, which is usually where the chain motor goes
Here are the basic support styles for the lift hill
Choose one style and keep using it for the whole lift hill.
In Moby's Steel Jungle, go to the flanges
Add the appropriately angled flanges to the corresponding supports
Make sure you don't put too many. Try to limit yourself to 3 per support, 4 if it is really tall
Now go to CPcisco's B&M Footers
These are the colors I usually use. If you use other colors it may seem unrealistic
Always try all the different footers to get the perfect placement
Here's what you should have
Now go to GRP B&M Catwalks. These are also in the scenery section
Add them along the entire lift hill. At the top, don't stop once it becomes flat, go down another gentle slope
Somewhere at the beginning, put a spiral stair. You don't have to, but it looks nice. These are in the evacuation set, not the catwalk set
Now open StationJim's Random things
Add an anti-rollback device next to the chain.
Here's your final result:
