I'm making a huge gaming engine and I need to make it as efficient as possible. For this reason, I decided that I would have to store most of the data externally and load it into the projector or movie as needed. I'd like to store everything in external casts that are not normally linked to the main movie. How do you import casts? The help file says you take an existing cast and set its filename to whatever cast you want. I want to be able to create and delete casts on the fly, during gameplay. What would be the easiest way to do this. Also, is there a max number of casts?
