Iblur, Idilate/erode Etc

[ior]

How's everyone doing their iBlur/iDilate/Erode etc? Pretty straightforward in Shake but not so much in Nuke. Guess I could roll my own unless there's something I'm overlooking that's already built-in? Cheers, -Ean

Blur, Erode (Fast), Erode (Blur), Erode (Filter), Edge Blur, Laplacian, LevelSet, Edge Detect and so on. Anything too special about the iBlur and iDilate that can't be solved with Erode (Blur) and Blur in Nuke?

Yup, found those, thanks, but I'm talking about Shake's IBlur/IDilateErode/IDefocus, with emphasis on the "I" before the node name. The shake "I" class of filter nodes all have nicer blending via a control image (usually a ramp).

That's what I mean (from the Shake docs).

There must be a way to do this from scratch in Nuke but my brain's not working right now.

ZBlur seems to give me the same functionality, and then some.

But what about IDilate/Erode? Shake's "I" nodes' have some nifty recursive expressions going on that let you change the number of steps by changing DepthSlice & KeyMix nodes to layer fine amounts of blur. How to do this in Nuke? I'm not a programmer.
