Remove land/water build requirements

[Trakt0rdeck 8]

A quick and possibly kind of stupid question for the ones more experienced modders than myself. See, I'm simply trying to edit a seawall for personal use and I want to be able to place it on the very cliff, i.e. the tile between the water and the land. Therefore I must be able to build on both land and water, and not either of them. How do I go about doing this? 

Any assistance in this matter would be greatly appreciated.

A tile can't be "between the water and the land", it is considered either "land" or "water". If it's even partially submerged, ie any of its four vertices is underwater, then it's considered "water". Land and water markers can be set in the Lot Editor - click the Land and Water tabs.

You may want to take a look into JS Seawalls on the STEX, they are plopped on that "intermediate" tile, but require lowering the water surface first. I'm not a big fan of this technique, the average elevation of the tile may vary, making it hard to align the models. Marrast's  seawalls on the other hand are placed on "Land" - the tile just next to the shoreline, which you have to flatten and bring to the same elevation, for the models to align properly, but this is can be done easily by plopping street tiles one next to the other.
