GUI Texture + Render Texture + "Custom" Shader

Hi,

I try to add a camera to a gui texture.

But the render of my gameobject with a custom shader (toon shader) doesn’t work…and If i use my render texture on a gameobject (like a plane for example) it’s ok.

I have to modify my shader ? GUI texture require specific shader code?

thanks.
