Imposter scale fix:
"Problem is in the MaterialFunction "/Engine/Functions/Engine_MaterialFunctions01/WorldPositionOffset/FoliageScaleFactor". Both of the TransformPosition nodes are set to output Local Space, the same as the inputs. Change their Destination to output Absolute World Space. This fixes the problem of the mesh instances scaling with the billboard sizes correctly.“
