Above is a diagram I put together to explain how I reference files into a new scene. The reason why I reference the files I need rather then importing them into each scene is because it allows me to continue to update the files, such as the individual character files and the set, But also lets me use the version I have at the moment to animate with. Once the final version of the characters are made, I will save over the old files with the finished version, but save it under the same name.
for example, hero1. then the scene will reference in the final version and be able to transfere all the animation I did on the old version onto the final version.
This way I can still animate whilst the modeller works on the chars. It also helps when it comes to rendering the final piece as yo ucan set up maya to render the referenced layers one at a time speeding up the process.
