Check this out! ReelFX rigging supervisor Josh Carey (nothing to do with my buddy Dan Carey except that they probably share the same good look) just posted his VES submission showcasing his AWESOME work on the Looney Tunes shortfilms.
I haven’t worked with the rigs so I don’t know how slow they are but they sure give the animators a lot control to achieve that crazy Warner Brother look.
It is finally possible to emulate the 2d cartoony look in CG and this will certainly push the medium to a new level leaving motion capture way behind or at least separating the two in a very dramatic manner.
Josh Carey is also the co-founder of rigging educational forum Rigging Dojo and seeing the tools he provided the animators with I immediately subscribed to their newsletter.
