Hello,
I’m reaching out here for the first time because I’m experiencing an issue:
When I do “Build Lighting Only”, Unreal Engine crashes.
My PC has a decent configuration:
-
CPU: i5-10400F 2.9 GHz
-
RAM: 24 GB
-
GPU: RTX 4060 8 GB
-
Disk: 931 GB NVMe free for swap
Here are the details of my scene and what I’ve done:
-
50 static meshes, mostly under 1000 triangles each
-
All meshes have Generate Lightmap UVs enabled
-
Lightmap Resolution: 16 for all meshes
-
Static Lighting Level Scale: 1.2
-
Indirect Lighting Quality: 0.5
-
Num Indirect Lighting Bounces: 2
-
Lightmass Importance Volume around the playable area only
However, Unreal Engine tries to allocate 98 GB of RAM, and then it crashes.
(Sorry for my English, I’m French.)
Thank you in advance for any help!
