Hi Walter, I don't know anything about WorldMarchine and you don't provide any of the problem images so I can't provide any specific answers. The best I can suggest it to check that the images coming from WorldMarchine are handled by gdal, so first stop would be to visualize the original data that comes out of WorldMarchine and the data that comes out of gdal_translate and gdaladdo. Only once you've established each of these steps works correct is it something the OSG/VPB will have an effect on.
