Managing lightmaps in a larger project?

Large assets can be a workflow problem for teams, especially if they're updated fairly often.

The cache server is part of the Team License, and is intended to help some with that issue. Instead of requiring each user to fully re-import, the server will cache recent version(s) of each asset. For a big enough project, the download is almost always quite a bit faster than a full reimport.

You could also try a revised workflow that has your teams working in separate projects, which you keep in sync using some mix of branching, submodules, Unity package import/export, and so on. Heavyweight changes made by one team (or user) will only affect other users on that particular repo. This introduces other problems, of course, but it's sometimes better than letting your teams stomp on each other with long wait times.

Thanks, I appreciate the response. The revised workflow is pretty out of the question at this point in production but the cache server is something we could probably fairly easily set up. Our individual levels aren't that big, but I would still wager that our in house servers could stream it faster than Unity takes to re-import everything :)
