Unreal engine 4

[Guest]

Because im going to be using UE4 in the near future, and if someone is using UE4 can they tell me what is the maximum size grid UE4 goes up to is it 1000 by 1000 squares or 10,000 by 10,000 squares quads or 1,000,000 by 1,000,000 squares (quads) also how many squares quads are there to a meter NPCs travelling distance, and the maximum celling hight is it 10,000 ft, also maximum ocean depth 10,000 ft? I need to know how big the island i make 400kms by 400 kms also from the beach 20km out then a varst ocean cannot go, so if someone has unreal engine 4 on this forum see if they can enter 1,000,000 quads by a 1,000,000 quads.
