Hi, I'm using the puget textures from the osgdem example (http://www.cc.gatech.edu/projects/large_models/ps.html) to create a terrain. But now my colormap is flipped along the Y-Axis. At first I thought that it would not be a problem and that I could just transform the texturecoordinates and that it is an "OpenGL uses different coordinate system" related problem. But things are not that easy: osgdem creates multiple LOD Levels, with an own texture for each tile. Now when the upper right tile gets rendered, it shows the lower right of the terrain in the colormap, the mesh itself is correct (or the terrain is mirrored, which doesn't make a difference, they just don't fit). When I flip the texturcoordinates, the upper right tile tile still shows the lower right part of the terrain, but now flipped around the Y-Axis. So the tile itself has a wrong texture and that is nothing what I could repair with texturecoordinate transformation.
I tried some parameters in osgdem like a negative Y resolution (-yy -10) but that just gave me strange and even more wrong results. So how do I fix that? The png files seam to match, and theoretically I could edit them, but what if I want to build other terrains (I have some very big files that none of my image manipulation programs can open...) Thank you!
