Hi all !

I always wondered how to use grayscale image to map a filter value. I mean how to simply say set values 0 to black pixels and higher where it goes to white gradualy.

For example blur more and more where the grayscale map is brighter.

HOW TO ??

Thanks !

Correct me if Im wrong but could you not plug the greyscale matte into your mask input on your node?

I tried it and it works as long as the grayscale is alpha.
