There are currently about 5000 scripts for 3dsmax so, it's pretty hard to find to figure out new ones. But for example Blender... It's really coming up recently in this aspect. :)
You might find this interesting, kind of similar to your cutscene editor. A friend of mine is working on a node-based state machine editor for Unity... http://hutonggames.com/playmaker.html
Updated the script, made it both "editable" as a cube or a sphere and separated segs and sides and added spherical mapping and negative s. Any way enjoy someone may find it useful/
hey renderhjs, what method are you using to pack those sprites? I was looking into something to pack arbitrary 2d polygons before, but I could never find any solutions.
@luke - It's indeed at an odd place.You can find it in the "Poly Tools" category, named "UVhorizontal" and so on. May be because it was part of polyboost before and they merged all the polyboost tools into "Polytools" category.
