This Itemset contains cliff items with a slope on one side.
The surface is called "Forest". It is used on vanilla terraforming hills but not usually as a driving surface as far as I see. The slipperyness of "Forest" is similar to Sand, but the acceleration is between Sand and Wood. For comparison: The space you need to accelerate to 160 on Sand, brings you to 203 on wood and to 184 on Forest.
The items can be moved horizontally on a 32m grid and up and down by 8m like vanilla Lagoon blocks. The items have different anchor points that can be switch by pressing "Q" for an easier placement.
Beside the drivable items there is a folder with items for scenic embedment. The itemset is ment to be placed beside the terraforming rockfaces. If there are gaps between the drivable items and the rocks the scenic embedding items are ment to be used to close the gaps. Towards the bottom the items embed themselves by having walls much extended towards the bottom.
Two 1x1 Outside Turns in combination need different adjacent items. Therefore separat straight and chicane items are placed in a subfolder in the Curve1 folder.
There is a folder with wooden bridges that can be used to transition from a left-side cliff to a right-side cliff and to Roads, Rollercoasters and Grass. For the transition to Grass a Bridge might not be actually needed.
Place the extracted folder into the Maniaplanet/Items folder.
