I was wondering if it was possible to make a multiplayer blender file, almost like Google Docs. If there is, can anyone help? thanks, sorry for the strange question
Currently this isn't possible and would require major changes to Blender.
Typically larger projects divide assets into many files so people can work on different parts simultaneously, this can be done so assets can be re-used in many places using Blender's library linking system.
For reference, Mango Open Movie used this structure.
