Hello, first of all i am very new at making shaders so if my question is very noobish please bear with me.
here is my situation i have made a blur shader for my post processing effects (something like SimpleBlur example). what i want to do next is do one more layer of blur filter on it and then do a pixel distortion on it. the solution came to my mind is store each level result as a texture then use that texture as input for other layers. but the output of each level is RGBA vector.
i was wonder to know how i can make this interface node ?
