Hi everyone,
I’m running into an issue when trying to build lighting in my Unreal Engine 5 project. The build either gets stuck at a certain percentage or takes an extremely long time to complete (even for small levels). I’m currently using Lumen for global illumination, but I’ve also tested switching to baked lighting and had similar problems.
My specs:
- CPU: [Your CPU]
- GPU: [Your GPU]
- RAM: [Amount of RAM]
- Engine version: UE 5.3
Here’s what I’ve tried so far:
- Reducing lightmap resolution
- Building lighting with only a few static meshes
- Checking for overlapping lightmaps and UV issues
- Switching between GPU and CPU lightmass
Has anyone encountered similar problems or found a workaround? Is this a known issue with UE5 or something that I may have misconfigured?
Thanks in advance for any help or insight!
