Hi Martin, Rather than copy the data could you just use a GLSL shader and read both textures and choose between the two based on the tex coords that are valid for each segment.
If you can't do this then you'll need to copy the data back to the CPU using osg::Image::readImageFromCurrentTexture and then subload this to the other texture.
