This is a set of PlatformSlopeStartCurve items.
The border overlays have been removed from every item and an effort was made to simplify the items as much as possible.
All items in the set can be embedded for 132 KBs.
The items range in embed size from about 24 to 35 KBs.
Unzip the items into Documents\Trackmania\Items\Stadium\PlatformSlopeStartCurves
Restart your game. In the map editor you'll find the items under the Items menu (F3) under "Custom"
Bonus feature: Every item has two pivot points; one at Platform height and another at PlatformBase/TrackWall height. You can switch between the pivot points by pressing Q.
