Famous light design made by Tom Dixon. Remodeled in Blender 2.92.
Geometry is made with modifiers. Data are live. It is possible to optimize topology and number of polygons in Blender. Main shapes are made from curves, the model should be very lightweight if it is needed. Materials are generative, made in the node editor for blender cycles. There are no additional textures.
Fbx and OBJ formats contains only baked geometry without materials.
