I need blur postprocessing to another postprocessing shader

[Attila_Schroeder]

I need a blur postprocessing effect for my cloud postprocessing shader because the dithering causes ugly spots. The dithering is absolutely necessary, because without it there are unsightly raytracing stripes. I think with a bit of blur it will be quite good. does anyone have any idea how to apply blur postprocessing to another postprocessing shader?
