What could that be and how can I get this correct?
a slightly optimistic test after depth or stencil attachments where set but before any of the color attachments are bound. So if both come from checkFramebufferStatus called during FBOViewport::initialize nothing is wrong a you should be able to ignore them as you don't use either buffer. If you don't want to see them just take out the test at the end of FBOViewport::initialize there will be a final status check after the color attachments are bound so if this one does not bring any message it should be ok. I'll try to look at the original problem which was rendering to a float texture with fbos. I know that it works in principal (we do it without OpenSG on nvidia hardware). So there might be only some parameter tweaking needed. regards, gerrit ------------------------------------------------------- This SF.Net email is sponsored by: Power Architecture Resource Center: Free content, downloads, discussions, and more. http://solutions.newsforge.com/ibmarch.tmpl _______________________________________________ Opensg-users mailing list Opensg-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/opensg-users
