Video Tutorial:

In real life, the edges of any surfaces generally appear slightly rounded or worn. They are never perfectly sharp. With the new edges slider in Lumion 8, your model will take on a more natural and weathered look, one better representing the real qualities of physical homes and buildings. Impart age and realism by smoothening the edges of adjacent faces. Soften the corners of brick, concrete, wood and other materials. A simple slider movement, a more realistic building. Easy. Effective.
