Currently using zylann heightmap terrain, when I try to populate a generated terrain mesh with tress on multimesh, them comes all upside down.Tried changing the y scale to -1, but it mirrors the terrain height. Terrain mesh normals are pointing upward.
To reproduce:
-Create a plane mesh
-Populate it with any other primitive with multimesh
-Generated meshes will appear on the backside of the plane (assuming the primitive grows up to Z+ axis)
