I need to disable the World Setting _Force no precomputed lightning_ to bake the light, but every time I save and reopen the project the setting gets reset to true.

I know World Partition and Static Lightning is experimental, so can this has to do with that? Has anyone else gotten static light to work in world partition?

You ever manage to figure this out?

Okay; I figured it out on my own:

There’s a cvar you need to add to your Engine ini file under the render settings:

`r.AllowStaticLightingInWorldPartitionMaps=True`

Can’t be set at runtime.

Thank you. I will mark this as the solution as I do not remember if I ever fixed this as I found other problems with WP and baked light and therefore switched back to not using WP. 🙂
