If you're using the same seed and the same generating algorithm, all the blocks already 'exist in waiting', right? Generation doesn't rely on data passed through from already generated blocks to ones in the process of being generated?
paramat wrote:Hm i can now see problems with this, because essentially you need the 2 opposite edges to have identical terrain, and perlin noise doesn't do that. Perhaps easier to do what kilarin suggested in the other thread, where i guess you would add an XZ offset to each layer in the stack.

emugod, ah that sentence has a double meaning, what i mean by that is: kilarin's idea seems easier for me to acheive in a lua mapgen, because it doesn't need 'circularly continuous' noise functions. Now consider how difficult things get at the corners of the world with 2 axes of conitinuity :P
