yes, as bloodsong said, Vue3 (and 2) supports 16-bit TGAs for creating heightfeilds (which makes me assume that the internal format is 16-bit...otherwise it would be really stupid). Bloodsong: a 16-bit TGA uses the green and red channel to make up the 16-bits, so if you display it in a graphics program it'll look like a mess of green and red, but as a terrain it is simply interpreted as a continous 16-bits and thus you get increased vertical resolution. Your generic graphics editor cannot create them. -karl
