I am comparing this device with the skydome device since I had to replace that for lighting and lumen to work, so here is a quick list:
PROS:
-Love the customization of the sun and how in-depth you can get with each lighting element (like fog)
-Love lumen control
-Love the new night sky and animated clouds
-Love the live preview from within UEFN
CONS:
-No control over ambient shadows
-Cant change the cloud type (only one type exists)
-Doesnt support custom skyboxes (or at least it’s not obvious - would be nice if its similar to how post process volume has an option to set your own material, to have something similar, and a provided list from at least 3 options from the Fortnite folder - Fortnite, Cartoony, Realistic). Changing the cubemap on the Skylight within Environment Light Rig doesn’t change the sky).
-Doesn’t support Camera Filters (from island settings - need to test but leaving here because lumen didn’t like them anyway)
-Can’t control auto-exposure (cant make dark areas) nvm, found that setting, but very obscure for new users.
-Can’t disable them in editor to debug what is active and what is not, and make them toggle in game.
