- New a default level and create a Landscape
- Sculpt the Landscape a bit, built lighting, save map
- Don't use any mobile Preview in Editor or the problem will not be reproducceble
- Run the map on Mobile(both IOS or Android)
- The Landscape is broken at the seam of each component; it looks like the same height information is repeated on every component
- Not only on Mobile, but now use Mobile Preview on PC, the Landscape is also broken
If use Mobile preview(Default High-End Mobile for example) before cooking and delivering it on mobile, no problem!
