Lighting built is broken

unsoft · February 18, 2016, 8:37pm

I keep getting message “LIGHTING NEED TO BE REBUILT”.
However pressing ‘built All’ or ‘built light only’ doesn’t change anything at all (lighting still need to be rebuilt and whole scene lighting is broken).

Hi Unsoft,

I don’t have an direct feedback on solving this one right away, but I do have some things you can try and some additional information I’ll need from you to continue.

General Questions:

Are you able to build lighting in another level or is it just this level causing an issue?
If it doesn’t build in that level, can you try building lighting in a new blank project and see if that works?
Can you open Swarm Agent and in the Settings tab, set the Verbosity setting to Super Verbose then copy and paste that log here in a text file.
Is this happening only in 4.10, or does it happen with other builds of the engine as well?
Have you previously been able to build lighting for this scene and/or with this version of the editor?

Things to Try:

Clean and Validate the Cache using the menu options in Swarm Agent
In your C:\Users[COMPUTER NAME]\AppData\Local\UnrealEngine delete these files. These will regenerate the next time the project is started.
Turn off your firewall/antivirus to see if lighting builds.
Try using the Verify option in the Epic Games Launcher for the 4.10 version of the editor you’re using and/or try to Re-install if it still fails to build.

Let me know the answers to these and we can proceed to troubleshoot this further.

Thank you!

Tim

I have the same problem, Lighting build failed.

There is superverbose log from SwarmAgent:

I solve it. This error usually comes from a null scaled static object that can be identified using the Map Check tool, it would display an error looking like this :

Error Cylinder6 Cylinder6 : Invalid DrawScale/DrawScale3D
