Render Render2Texture to Texture?


I am trying to render a scene to a texture - works quite well - which is using a shader - also workin. Now I want this textured quad to be rendered again to texture. Thats the point where I stucked. I built the scenegraph the same way I did before - just skipping the first render to texture quad in the renderqueue this time and setting up the new texture renderer.

Is there something special I have to pay attention to or is it not possible this way?

thanks in advance
