Utilizing Library Linking with a team! How would this work!?

Hey guys, so i didnt really know where to put this so feel free to move it.

So im working with some people on a project, - its in the Game WIP, (Cool Survival Horror project)

Now i have modelled a Church area, for one part of the level,

I want to hand it off for others to Texture and Light. But i may want to make changes to my file while they are doing it.

is there a way to let them mess with only the textures and lighting, and also that when i make changes when they save or load it again both their changes and my changes are updated?

So that we can all work on it at the same time?

Let me know if im not being clear

Thanks for any help
Josh
