How to use: Extract the folder into the Documents/Trackmania/Items folder.
This Bobsleigh itemset includes turns with 15° and 30° angles, and also items with a 6° slope along with flat items. So in comparison with vanilla Bobsleigh items more turn angles are possible as well as slopes. This concept makes it necessary to leave the Trackmania grid, where items usually can be placed on. Instead the items snap to each other. They can be connected to each other by using the Item mode, hovering over the item you want to connect the new item to and by adjusting the orientation of the new item with "+", "-", the right mouse button and "Q".
For the start a special item on the grid can be used to be find in the connections subfolder.
When you connect the items to each other use the + and - bottons to change the direction of the items by 15°. Use the right mose button to rotate the item by 90°. You can switch between the pivot positions by pressing Q. This exchanges the place where the connection happens without rotating the item.
In the transitions folder also several large platform items can be found, which can be used to connect the Bobsleigh to on grid vanilla blocks by placing on grid vanilla blocks on these platforms.
Be aware that changing sections of the route inbeween other sections late can be difficult, because the following sections will likely be not connected to the changed section. For such a connection the platform items can also be used.
Something to be aware of is also that shadow bugs can occur with a lot of scenery, especially if the scenery casts shadows on the track. I recommend to use the items in the sunlight.
