here is a blur node, I haven't tested it
2007/11/30, Frank Lenhard <franky(at)ixdream.com>:
though i dont know EXACTLY how to do it, i know that you can use the
compositing tree to modify your shader tree. means you can get parts
of your shader into the compositing and blur/cc/whatever them, and
then bringing them back into the rendertree.
i am sure someone here can explain in detail how to do it.
