Wrong LOD generation when Set LOD Group node in Dataprep Recipe

Hi all,

it is very strange what I get after Execute and Commit (or when Update Datasmith Scene using same recipe): LOD Levels higher than 0, 1 or 2 for every SM gets swapped materials… if using LevelArchitecture or Deco Groups… I’ve tried several node orders but result is obviously same.

UE4.25.4, Revit 2020.2.3, Datasmith plugin

FAR: All SMs have LOD >2 (Group Level Architecture)

NEAR: there are some SM LOD 0, others, depending on screen size, from LOD 1 to 3…

Materials swapped? Wrong node order in recipe?

What do you think?
