I am going to throw my two cents. Rear window was a great opening to working with someone. Chris Dailey and I worked together for the first time and have to say it was one of the best things I have done in regards to animation. Not that my portion of the project was great, but the learning process, working together to create something, and making a new friend. I was nervous at first about working with someone else on a project. I worried that my skill sets were not up to par, but Chris was patient and pulled me along (encouraged me) and we were able to get the project done.
I did not work much on TWO or SO. I rendered and textured a lot. I went to the hash bash and learned how to animate but nothing I did animation wise made it to the final versions. So for a large project like that I can not comment on. Chris and I are working on a short right now. It is his story and he is the director and we are using some of my assets from Cupids Sick Day and I am happy to say this story line fits in perfect with what I want Cupid's Sick Day to show.
We meet weekly on Skype to discuss progress, work on story and eventual we will get to rendering. Sometimes we just talk about issues of life. But the collaboration can work as I feel it has for us.
I would love to see another community project. I will help in whatever way I can. We got to get "We Bought a Coffee Shop" done first
