Short answer: Yes, sort of. Long answer: At this point they are all still the same terrain tile. Once it is stamped it is part of that tile. Then after I'm finished stamping, I'll let SECTR slice the terrains and they will become separate terrains. At that point, Gaia's stamper is pretty much out of the picture. It has already been stamped and is 100% Unity terrain. Basically the plan is that I'll use the grid as an outline of how the tiles will go together as I plan my stamps and stamp the terrain. It will also give me an idea of how the pieces will fit together with their neighbors and I can strategically plan seams in the middle of valleys so mountain ranges will block distance view and provide additional occlusion which will hopefully help with performance since multiple scenes will be loaded at a time. But until the terrain is sliced after stamping, I wont be using spawners at all. Spawners should only be run on the small terrains. This will give max coverage. Plus trying to spawn on a 32k terrain will probably lock your computer up and cause it to hate you.
