I got it working. The issue is that readImageFromCurrentTexture() doesn't support TextureRectangle. I modified my program to use a Texture2D instead and it works now.
Adding TextureRectangle support to Image doesn't look like it would be too hard except that GL_TEXTURE_BINDING_RECTANGLE isn't a readily available constant. (it shows up in gl3.h in the 3.1 section, but I'm sure there's an earlier extension) Thanks for the help, John ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=48085#48085 _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
