Quest, re-read your last line in #30. I'm saying that it's the SAME complexity, and that at 4096 you are viewing a vaster slice of it in the Terrain Editor, with no need for tiling. A 4096 texture IS as complex as 64 512 x 512 textures, in fact exactly as complex. Without the time-intensive process of making 64 of the smaller terrains and arranging them. If you wanted to tile 4096x4096 textures, though, then I can see where you're coming from. Still, you're looking at a very finite amount of them : 33 Million polys at render-time is no joke. There's not enough RAM in the world to remap the Earth itself in this fashion, for example... Now we're getting on into Mojo-land, though... (grins) So as long as you guys aren't multi-tiling huge textures for some massive project, then I can't see any point to tiling at all... Make any sense now? (you made sense to me, anyway!)
