Hi Tom, I am new to X-Plane scenery development but have more and more fun! I working on a German regional airport near Berlin which I quite well know as a pilot. I made lots of photos and created most of the buildings. I made runways, taxiways signs and so on with WED and placed all the buildings. I defined a boundary and exclusion zones to exclude standard scenery. All that looks fine. Now comes the next step: foot ways, roads, fences and polygons for grass and dirt... I do not have orthophotos to use as polygons since there aren't free ones for Germany. On the image you see the biggest problems: The polygon textures (dds Files of 256x256 px referenced in the pol file referenced in WED) are distorted. And the edges are sharp, what is not very realistic. The sand area in the left is not in the right resolution... How can get the textures tiled and not distorted? How can I dither the edges between grass and foot way? How can I modify the resolution? (SCALE directive?) The pol file is like: A850DRAPED_POLYGON LAYER_GROUP airport -1TEXTURE_NOWRAP gravel.ddsSCALE 25 25 A question to the roads: I've excluded roads but they are present anyway (may be from OSM generated...). How can I get rid of them inside the airport? Any help is appreciated. ThanksNils
