Should i or not? If not, so where i should still use lightmapping in that case?
Hi newbprofi -
Unless all you scene’s lights are dynamic (Movable), then yes you should use be using Lightmass. The BP_Sky_Sphere which has the built in Day/Night cycle is not actual a light source. The Blueprint will take a directional light source as reference for the corresponding light vector (to control the sun’s angle and location) and will influence Indirect Lighting in the scene, but the Sky_Sphere itself will not generate shadows on any assets in your level. These shadows are typically done, in most default and sample maps, by the directional light in the scene. Since this light is by default set to Stationary, the lighting and shadows are lightmapped at distance from actors in the level and up close run dynamically. So without a Lightmass run, these lights will not render correctly in your game and will have to be converted to dynamic.
Let me know if you need me to explain more -

Oh, i c. If directional light set to Movable, then Lightmapping is not used for that automatically.
