But is that necessarily a good thing? Terrain complexity is the enemy of the cart, the plow, and the foundations of buildings. I actually prefer to stretch 512 height and biome textures over large map areas because it smooths the ground out.The stretching of small height and biome textures also leads to some feedback on your macro. Refer back to my post #24 above . The 1st and the 3rd pictures were taken standing on the same hill looking in the same direction at the same hills in the background. The only difference between them is that in the 1st pic, I left all the map size values at the default (1km wide, 250m height) while in the 3rd pic, I set the map to be 4km wide with 500m height. All the textures are the same in both cases.In the 1st pic, observe the patch of grass in the lower right corner. Also in the center background, observe the single tree against the skybox atop the dome-like hill at the left end of main chain of pointy hills. With the map at this 1km size, every hilltop, even the tips of the pointy ones, was crowned by a patch of grass, and many hills had single trees growing on their summits. In the 3rd pic, however, with the textures stretched over the 4km map, these anomalous spots are gone.My theory on this is that on the small map, the tips of even the spiky hills had small flat areas on top, just barely big enough to stand on, which the angle values for the biome materials naturally slapped grass and/or trees on. At the larger map scale, however, pulling the sides of the hills further apart, plus increasing their height, interacted with how voxels connect to round off the hilltops, eliminating the flat spots where grass and trees grow.It appears, then, that the macro's effects are somewhat dependent on the horizontal and vertical dimenions of the in-game map combined with the ratio of that to the size of the height and biome textures. I don't consider this to be a fault of the macro---it's probably unavoidable. I just mention it FYI and for future referrence by other world-builders. If you have small spots of trees and/or grass on your hilltops, you might be able to get rid of them by tweaking the map size in ME's Scenarios.sbx file instead of wrestling with the macro or other devices in WM.
