In the past I've extended the TerraGear uv generator to allow seamless tiling of the OSGB36 grid [--useUKgrid], and within a UTM zone, to remove the discontiunity at degree-latitude lines that the current TerraGear scheme gives, so unless something drastic has changed since then, it's definiately TerraGear that generates them. FG does the ocean tile though, IIRC. With regards to the slope texture stretching, unless I'm very much mistaken I've seen exactly the same problem in MSFS 2002. Cheers - Dave |
