Supporting Lightmaps across Unity versions

Unity Engine
1

I have a scene that I’d like to provide to others but it needs to work with multiple versions of Unity. e.g. 2018.4, 2019.1, 2019.2, 2019.3 etc.

I’ve generated the lightmap data in 2018.4 and I’d like to make that scene (with lightmap data if possible) to be imported in a package and used in newer versions.

What is the best way to achieve this?

Hi
It can be a bit tricky, but try just shipping the scene with it’s LightingDataAsset and the lightmaps. Hopefully the upgrade will be ok, but it will probably tell you to rebake. A lot has happened between those versions.
