I am trying to import a 3ds file. Using Vue 4, latest patch. If I modify the geometry of the object before importing into Vue, The object in Vue has soft edges or is 'smoothed'. I need the crisp edges to show shadows. Attached is a top view of some roof forms - on the lower right the geometry was NOT modified before importing --- upper left the objects were slightly modified in the original software. All were saved together. ( I realize the sun angle is not the same however the result looks the same) All the objects are in the same file. is there some way to prevent the 'smoothing' that makes the crisp edges look rounded within Vue or whatever is modifying the way light interacts with the crisp edges? (does any of this make sense???) Many thanks, Rivers
