Result : while displaying the Nanite version of the landscape, the paint layers behave erratically (see video : [Link Removed]

If rebuilding the Nanite data, the bug gets fixed until the user starts painting again. 

None of this occurs on a landscape where edit layers are enabled. 

Steps to Reproduce
  • In a new map, create a new landscape with edit layers disabled
  • Create a landscape material with 2 paint layers A and B that write 2 distinct colors and assign it to the landscape 
  • In landscape mode, in the paint panel, associate a landscape layer info object with each of the 2 paint layers
  • Paint a bit of both layers on the landscape
  • Select the landscape actor, enable Nanite on it and hit the Build Data button to have the Nanite meshes rebuilt
  • Then paint again one of the layers on the landscape
