Building Worlds in ‘Fortnite’ With Unreal Engine

" summary

Epic describes how Chapter 2’s island is built using concrete UE features: runtime virtual texturing combines terrain and props to cut shader cost (≈1 ms to update, ~3 ms saved on PS4 in heavy views); the new landscape layer/spline system lets non‑destructive edits and toggleable stacks; a water spline system creates flowmaps, a localized fluid sim and foam; waves use a limited Gerstner waves set (6 on PC, 4 on mobile) and the quad‑tree Water Mesh for LOD, and everything is integrated into SkyAtmosphere and volume clouds.
