@3DG That’s interesting. Did you mean that you paint individual hedge leaves assets on curved box object ?
This feature has been a life saver for me creating curving, winding hedges, you just go to Assets > Nature > Hedge and then filter on “Single” (for some reason D5 then makes you select Hedge again), then choose the Paint Brush option> pick your hedge variety> set Radius to maximum> set Density to maximum> select ‘Align To Terrain’ and then click on the material you coloured your hedge with in Sketchup etc - then it will all instantly turn into a lush hedge exactly as you want it to be
