Can't build lighting, builds all but 1

I can’t build lighting for 1 thing,

I used a method to see what’s not being built, and the output log gave me this:Begin Map

Cmd: DumpUnbuiltLightInteractions
Lights with unbuilt interactions: 1
Light LightSource_1
Primitives with unbuilt interactions: 1
Primitive FoliageInstancedStaticMeshComponent /Game/Levels/Level1.Level1:PersistentLevel.InstancedFoliageActor_0.FoliageInstancedStaticMeshComponent_1

Why isn’t the lighting being built for these?

Hi PlanetRenox,

When building lighting with foliage you have to make sure to use a lower lightmap resolution otherwise the lightmap for the instances will be too large and will not build due to the number of instances painted.

Try using a lower lightmap resolution or disabling static lighting for your foliage.


I REMOVED all foliage and it still wont go away!

I had to empty the foliage load in the editor, basically remove it all if im not using it…
