Dynamic Light and Foliage Shadows

I have a problem, i want to make dynamic day/night system in open world(size maybe something about gothic 2) and I have some questions. Which light is the best for open world games(I heard opinions about Movable, but it was old comments, and want to know your opinions). If Movable then is there any way for dynamic shadows in foliage? If you have any tips for Open world, I hope you will share with me:p

Movable Lights are the only lights that well, can move.
They cast dynamic shadows only.

I’ve implemented a Day/Night System by rotating a directional, movable Light around, while also haveing a stationary SkyLight with predefined Cubemaps for the Time of Day.
Read the Documentation if you want to know what suites the best.

I have an error after changing SkyLight from Movable into statnionary “InstancedFoliageActor_0 Large actor receives a pre-shadow and will cause an extreme performance hit”.
