Hi Ricky, I am sorry I don't have more to offer. I was hoping that my changes would help you, but PNG loader most certainly uses uncompressed formats so your problem might something else. Try OSG_NOTIFY_LEVEL=DEBUG_INFO or even better run it with some GL debugger to see what is going on under the OSG hood.

I mysteriously solved the compiling issue I had =) Unfortunately, it doesn't seem to solve my problems, and I seem to have issues with the png as well. Here is the GL error message: Warning: detected OpenGL error 'invalid enumerator' at After Renderer::compile Should I use specific image/texture settings to get it working?

I am on windows and have not checked GLES compatibility though.

What osg revision is needed? Ricky On Fri, Apr 23, 2010 at 12:08, Riccardo Corsi <[email protected]> wrote: Hi Wojtek and Robert, thanks for your replies. I'll try the patch in the evening and let you know if it fixes the problem on my side. Robert, the restricion on the values 1, 2, 3 or 4 that you mention is related to ES profile only, or even to openGL 3.x and 4.x ?? That might be an issue to address when reviewing the different plugins.

If you can rebuild OSG you may try attached patch to Texture2DArray class. I intend to post it ultimately to submissions list, but lets say its in "alpha" version and I want to make one more review before posting and other tasks prevented me from doing it, yet. You may test it. There is a chance it will solve your problem.

I succeded in fixing the TGA settings but not the DDS. Here the setting for the different image types as read from the plugins: I'm afraid I don't have an specific answers on this topic as I haven't use texture arrays and compression, but the inconsistency in how the internal texture format us used, i.e. something that works OK for Texture2D doesn't work for Texture2DArray, makes me wonder if there is either a bug in osg::Texture2DArray or with the OpenGL driver. As an aside one of the things I found with the GLES port was GLES was a bit more picky about the internal format not being one of the 1,2,3 or 4 values that some of the plugins still use.
