A set of variations on the ring effects and checkpoints, where instead of a ring, it's a bar (based off block 11-4-1-3, so these should line up with those). Trigger has a vertical height of four blocks.

Since custom effect rings only work as custom blocks, all of those are, well, custom blocks. Place the Blocks folder of the pack in Documents/Trackmania/Blocks (Not /Items, that's where the Items folder goes).

Only one air variation is included with each block, so if it shows up as a ring, just enable air mapping (or place it and remove the pillar).

When using the checkpoints, make sure to link them if you are doing it wider than one block. To do so, click the "Edit Block Properties Button" (The second to right button, looks like a cube with a gear), select each checkpoint, and click the chain icon in the menu that pops up to change it to a linked CP. Also make sure to set the group to the same as any checkpoints it needs to link with.
