I imported 3 materials and 4 meshes from the Quixel Bridge and now I can’t build Lighting, I just get a message in the corner saying “Lighting build failed”.

When I delete those materials and meshes and restart the program, I am able to build it again.

I do not get any detailed report on the error.

Are you seeing anything in the logs? Anything relating to the specific assets maybe.

Navigate to Top bar → Window → Developer tools → Message log and see if there is something going on.

You could try deleting the Swarm Cache and looking at the log in there. Cleaning the cache and checking the logs info can be found here…
