Hi Mat
Yeah I mentioned it in my Maya 2008 thread, a plug in of some sorts would be great. I've never used mudbox just Zbrush, the lack of the painting tools made it a bit of a letdown in my opinion.
But to be honest I got to grips with Z pretty fast, which helped a lot then again I only use about 10% of what it can do.
As for the devlopment of mudbox, I really think that Autodesk will throw loads into it, lets face it the level of detail that you can apply in sculpting packages and the interactivity between the user and the software via tablets has made a lot of CG movie (and still) characters the dogs do dars, this cant of gone unnoticed at autodesk, also streamlining the intergration of the sculpt into the pipeline would be a huge bonus as I find it a bit of a pain messing about with settings all over the place.
