I need to create a scene with a spinning space station. This movable actor is 30km (18 miles) wide and the player can see it all from a distant, or enter inside seamlessly.
The scene is illuminated by a single directionnal light. I’m looking for a solution to get both sharp shadows at close range and rough shadows in a 50km range radius without performance issues, if it is possible.
I’ve read the lighting documentation but I’m not a UE4 shadowing guru… Could you help me on this or point me existing exemples?
