teamwork on same project

we are developing different big applications with a lot of assets (3d models) and we are unable to work with different people on the same project because it does not seem to be possible to work simultaneously on the same file and if we use 2 copies it is not possible to join the files

Is there anything we could do?

This has been asked before multiple times. Look at version control workflow and collaboration questions (points to the search box up there).

Make a script that saves the position, rotation and scale of each object to a text file(one text file per scene). Attach this script to all objects.

When everybody is done making changes to the scene and all models are imported: Merge the text files. Drag n Drop all assets into the scene -

then have a script that updates the position, rotation and scale of each object in the scene based on the data in the text file.

It's a bit of a hack, but it should get the job done and save you some time.

I read the anwsers but as is stated in another forum

You cannot merge the scene files, even with Asset Server (shocking oversight IMHO). So you cannot have multiple people working on the same scene. Therefore you have to manage the scene updates manually by assigning someone to be the master of the scene and noting other people's changes. Or maybe by writing a tool to export the scene to XML or similar and/or having a script rebuild the scene.

This is the problem we have
