Lightmass is a very CPU intensive process and can take a while depending on the number assets in the scene and system specs. Large scenes can take an extraordinary amount time depending on these factors, especially for a single machine. While it may be a common complaint, it’s hard to get around all the calculations that need to be done for accurate shadows and GI to be baked. You can always lower the quality settings in the World Settings > Lightmass tab.

If you want quicker build times, it’s better to use a smaller scene, reduce the number of objects, and lower lightmap resolutions to start with.

Larger scenes will typically use dynamic lighting in lieu of baked lightmaps. The texture memory used for storing the lightmaps can become higher for larger scenes. With 4.8 there has been a push to make larger worlds easier to create and better with performance with a large number of objects and using dynamic lighting.

Thanks . I’ll do the suggestions you mentioned. I actually DON’T want high quality lighting. UE4 seems to assume that I do. I just need enough to cast sunlight on my map. That’s it.

I’ve already dropped lightmass settings to preview & adjusted static mesh resolution and it is still taking this long. I’ll remove objects see if that helps. Are there any other quality settings I can drop? Any way to force the load over the the GPU?
Also, I’ll try loading 4.8 see if that helps.
