Hi Mateo, I'm a bit confused as to what you are actually doing, my best guess is that it's something like shadow mapping. The best place to start is to have a look at the osgprerender example and others similar to it. Have a look at all examples that use osg::Camera when doing render to texture, also have a look at the osgShadow library as it's osg::Camera usage will show how to set up the Camera to create a render to depth texture.
