I like Mocha, but the above changing of their business to an inferno, subscription based model does not appeal at all and seems to be missing the mark with the way a large chunk of the industry is going (i.e. the garage based studios, with a couple of people working, ...the ones who don't have the cash for an inferno, and do amazing stuff with desktop systems, where speed of execution is not as important as quality of the end result). As for the comments about companies moving away from having in house engineering depts, i think that is way off too, ...being able to script applications such as Nuke, Maya, Shake, etc, in common languages such as Python means even artists can tool up a special need addition to those apps, and I have IT friends I know i can rope in if I need a tool made for me, ....much better than waiting for a large software supplier to build something that might not be of any use to anyone else.
As i say, I like Mocha, but i always wonder where Imagineerings marketing dept is thinking when they're driving the company (the tools are expensive for what they are, especially Motor, Silouhette Roto is a much better price for a solid roto app. The freelancer specials Imagineer did over Christmas were the best marketing move I've seen from them, ...it looks like they're back to their old ways now though. Goodluck taking on Discreet.
