Otherwise, we can just set everything to movable, enable the Raytracing and use those RTX graphic cards we paid for.

If I want to bake, I usually set the DirectionalLight to Stationary, to get better speculars and the ability to blur shadows in real-time with the Distance Field Shadows. Just remember you can modify it if you select the Skylight and the DirectionalLight. I don’t want to talk too much about light mobility in this blog post. – SkyAtmosphere: this is NEW! It replaces the former “Atmospheric Fog” component with a more realistic scattering of the light. – DirectionalLight: this is the sunlight. Remember that this alone will not show you any blue sky, but project the light from a cube map or the atmospheric fog. – Skylight: The diffuse-light simulating the sky. – CompassMesh: as the name says, the compass-like mesh. The Sun and Sky blueprint’s components are: BE CAREFUL! The Sun and Sky blueprint can only simulate the natural lighting during the day if you go too far before dawn or after dusk, the top hemisphere will turn black and the lower one will give you a weird bright-gray glow. I would say this is the variable you want to animate in the Sequencer to simulate a timelapse of the day. With Solar Time, you can choose the hour you want to reproduce. You can pick the exact day of the year trough Month and Day. The North Offset is just a way to rotate the entire Sun and Sky system, so feel free to change it to match the north of the project. Latitude, longitude and Time zone are details you can google easily. Side note: You still have to place the ExponentialHeightFog manually if you want to get a lower hemisphere / fog effect in your scene. Said so, there’re still a bunch of settings under the hood that maybe you want to modify to get an even better result. These settings are what you need to reproduce realistic lighting, which coincides with the one of a real place in the world.

Like every blueprint, the “Sun and Sky” will show you some editable variables in the Detail panel, like latitude, longitude or Solar time.
