Pack originally made by Lemicin, I am simply uploading this on there behalf.

This pack allows you to add CPs onto pools by adding a thin Checkpoint layer above the water.

How to Install:

simply extract the zip folder into your trackmania/blocks/stadium folder.

How to use:

the CPs are located next to the ring CPs in menu 12, I recommend placing the ring CPs in ghost block mode so it does not replace the already existing pool.

you can Link PoolCPs by clicking on the small cross located at the center of each block.

Known bugs:

For some reason if you undo using control+Z it will sometimes remove all the PoolCPs you have placed. this seems to be midigated by saving and reloading the map file.

Update:

added the triangular block created by TNTree based on the original 1x1 block made by Lemicin added the platform block also created by TNTree
