Hi. I`m designing airport and after struggling with airport background tiles (solved) I noticed after compiling that textures new problem (another ) . I`ve sliced image from SBX to 34 2048/2048px parts in Photoshop. In gmax I applied them to each segments. No problem with black lines between polys finally. But.. My airport is generaly flattened. But some tiles covers area beyond flatten polygon. Area is sloped with some hills and all. Is it possible to use that textured polygon to be not at AGL and blend with mesh like photoscenery does ? If so could you give me a tip what kind of programs I will have to use and what is a method. I suppose I ought to use elevation data and textured polygon and blend alltogether. I would not like to use photoscenery for many reasons especially because rendering time and worse resolution. Sorry for my english I hope it`s understandable what is my intention.
