Well, it's supposed to be for a symetrical terrain, since that's where the original idea came from... Reason being is that when you get the figure from the greyscale, you have to shrink it next to nothing along the z plane, which you could not and get the desired effect with a regular terrain, in this particular case... And yeah, he did add some very valuable info to mapping textures to terrains, symetrical or otherwise... :) But tha'ts some impressive work that Eric has demonstrated on top... Let's hope he shares some of his experiences as well... :)
