Hi, Thanks for the responses. I tried Robert's initial suggestions, but they get
Code: Warning: detected OpenGL error 'invalid value' at after RenderBin::draw(..) on my system. Glenn's suggestion basically worked, although the image was literally shades of red. So I looked at the DefaultFont source, and tried GL_ALPHA. Maybe that would have worked if I turned alpha blending on etc. So just for kicks I tried GL_LUMINANCE (for internal and pixel format) and it worked! So, for the record, here is what worked best for me: Code: img->setImage(w, h, 1, GL_LUMINANCE, GL_LUMINANCE, GL_UNSIGNED_BYTE, data, osg::Image::USE_MALLOC_FREE); // works! Thank you!
