Hi
Recently I’v edited few big terrain shaders and was in desperate need to reorganize the whole graph (preferably in automated way) as it was such a mess 
Since I had in past some experience with Msagl graph building tools, the idea of using was born.
After few hours of hacking’n’slashing through UE4 & Msagl the prototype was born (although it is not very pretty).
All in all, here it is in action: http://mxadd.org/UE4/sample.avi and here http://mxadd.org/UE4/ReorganizerAlpha.7z you can download the whole thing and try it. (see Readme.txt inside archive for details).
Let me know what do you think about this tool, it will probably get some more love in upcoming days, since I’v found it prety usefull in organizing big nasty shaders (postprocessing / terrains mainly).
