Hi Coz, If your RTT is set up correctly, then It might be simply that the texturing you are using in your shaders of your main scene graph (that uses the RTT textures) aren't doing what you want. From your texture it does kinda sound like your aren't using texturing though... There is so much unsaid about your setup I can't really guess what might be up.
