I left off asking some pretty big questions on my last blog, and have been doing some research in the past couple of days to answer them. To recap, I was writing about some of the problems that can occur while working in the industry of CGI, specifically how companies handle working on films when technologies are being improved so rapidly. I left by asking whether companies switch over to new technology despite possible differences in software? Or do they continue working with what they have and use the new stuff on the next project? Well, it turns out that most of the changes in software are so subtle that often larger companies such as Pixar and Dreamworks will update to new software and incorporate it with what has already been developed. Since the new editions of software already in use still has the same capabilities, if it is uploaded onto the company server, the big picture will be virtually the same, but more options may be avaliable for the more detail oriented if time permits the artists to go back and make a few small improvements. Something that I want to point out is that with digital animation software, a big difference between software editions is often the capability to handle personal projects or large projects. On several occasions cheaper products will come out for the consumer while the bigger and more effective and expensive model goes to the big corporation. There is a really well laid out section of Pixar's website answering FAQs about Renderman that I suggest anyone reads if they are interested.
