Material tree browser

Hi everyone.
I'm looking for a script i remember using not so long ago (a couple of months)
I'm preety sure i found it here on scriptspot, yet i cannot find it again.
Its a visual material browser, node-based.
It looked similar to ShaderFX, however its not identical.

Its not TMG, as i remember it had curved lines linking different maps to their parents (like ShaderFX).

I also remember it was a script i ran inside MAX, not an installer, like ShaderFX. It came as a single .mcr file, and i think it was freeware, unlike ShaderFX.

Also, when opening the script window, i had to click a button and select what scene/mat. editor materials i want to include/show inside this visual node-based editor.

If anyone could help i'd be really greatful.

PS. I'm using max9 64-bit, so it worked on that.
