Hi Hartwig, If you set a format that isn't supported by the OpenGL driver and you get an error then so be it. Fixing the code that sets up the image with a valid texture format is what should be done. Trying to catch and correct for a problem in user application set of OSG data is rather pushing what the OSG should and can be expected to do. This is particularly the case when what formats that might be supported that can be driver dependent.
