I NEED HELP WITH BAKED LIGHTING (GPU Lightmass)

Hello @mr_seal1, I’m sorry to hear you’re still facing this issue. I couldn’t find any specific references to this error, but I encountered a similar problem in these cases:
Light Configuration:

  • Set lights to Stationary or Static (not Movable).
  • Ensure “Affect Static Lighting” is enabled for each light source.

Nanite Compatibility:

  • Objects using Nanite may not bake lighting correctly. Try disabling Nanite to see if the issue continues.

You can also use the “Light complexity” and “Lighting Only” visualization modes to diagnose lighting issues.

For now, this is all I can think of. However, I’ll keep looking into this issue to help you find a solution. As soon as I have any updates or new findings, I’ll make sure to comment on this thread.
