When baking light, I have an error.
I tried all the tips on the forum but I can not solve this problem. Can someone help?

Hi!

Try to clean the cache in swarm agent! :slight_smile:

I tried, it did not work( Also tried to delete folders “Saved” and “Intermediate” in the project.
I also noticed that lowering the lightmap resolution can remove the error, but it does not always help.
