Performance hit on Sky Box

I keep getting this Warning with the Ultra Dynamic Sky i recently bought from the Marketplace.


Does anyone know what this is? Because i have looked every where and i can’t find that setting?

It sounds like you’re using static lighting but forgot to add a Lighting Importance Volume.

Here’s someone who fixed this issue that way: Stuck: Lighting Issue - Rendering - Unreal Engine Forums

Thanks for the Link… and from what it’s say’s, that means i would have to put a volume around the entire skybox/world.

Nah, that would defeat the purpose of the LIV (Lightmass Importance Volume). You want to put the LIV only around areas in your level that are either readily traversible, or are in close enough proximity that accurate lighting is necessary. In many situations, static meshes are, by far, the most impacted by the LIV. So put them around pathways, buildings, or areas with many static meshes. The LIV just let’s the engine know where the focus should be set. Terrain and skyboxes typically directly affected by lightmass.

Skybox should use Unlit material.
