Result : there are significant differences between the generated Nanite mesh and the original landscape mesh (see [Link Removed])


Note : the bug was originally reported on this UDN : [Link Removed]


Steps to Reproduce
  • In the Sandbox/LDModeling/Terrain project, open  the map : LandscapeNaniteNonStandardZScaleTest


  • Create a landscape with a non-uniform scale (e.g. 100, 100, 1000)
  • Sculpt some mountains
  • Enable Nanite on the landscape actor

Then : 

  • Make sure that the Nanite landscape data is built (Build->Landscape/Build Nanite Only)
  • Switch between Nanite and non-Nanite version of the landscape and observe the difference
