Elements contributing to day / night cycle
- DirectionalLight, actor in the Persistent Level (Yliakum). Casting light globally in a certain direction.
- Intensity
- Light Color
- SkyLight, actor in the Persistent Level. Stores the color of the skybox and influence all items in the game with indirect light based on the skybox color.
- Intensity
- bp_sky, actor in the Persistent Level, which contains all the logic for rain/snow/fog/... , clouds, time of the day, the actual skybox which is a static mesh (dome).
- Light, scalar parameter on the Material applied to the skybox mesh
- ExponentialHeightFog, actor in the Persistent Level, managing the fog. Careful to change its color at night, or the skydome will stay lit.
- Light color
Static vs Dynamic lights
I tried with many different settings and Lightmass is crashing on our hydlaa level very often. Trying to create a minimal set of objects exposing the crash seems not possible, as when you delete some objects may stop crashing, but then deleting more seems to stop crashing, so looks like the combination of meshes, not one particular mesh.
The crash happen with SkyLight and DirectionalLight set as Stationary and also with SkyLight as Stationary and DirectionalLight set as Moveable.
The crash does NOT happen with SkyLight as Moveable and DirectionalLight set as Stationary. So we tried this setting, the problem is the size of the generated BuiltData files.
