Terrain tile = 0, holes in water block

#1 The way TGE has always handled its terrain makes doing what you want to do rather difficult, if not impossible. From my work on the lightmap generation code I have to say there is just so much infrastructure surrounding the use of repeated terrain that unhooking it could cause more problems then it is worth.

I'd almost recommend using TGA since I hear that has the support for near infinite terrains with different types of area lighting. Depending on how my game development in TGE goes I too might have to port over to TGA, though I don't want to lose Linux/Mac support :grumble:

You might take a look at the MMO Toolkit because IIRC they have some support for larger terrains. Unless someone else can chime in with more info, you just might be stuck with little islands everywhere.
