Hi Robert, You had mentioned substituting the shaders via scene traversal or state inheritance. I know how to enable/disable/substitute (perhaps cripple) the shader. My problem is setting the scene up properly (either through scene traversal or state inheritance) such that the RTT's CameraNode is crippled while the main Producer camera's shader is fully intact.
Basically, I just don't know how to implement the state inheritance or scene traversal aspects such that my "crippling" and "enabling" functions (that I have written) can be called prior to the rendering of their respective cameras.
