The black metal outer frame is filled with orange painted perforated metal moving panels. By changing the angle of rotation of the mini-panels, you can change the level of illumination in the zoned spaces.
Attention: the perforation of the central part of the panels is made with a texture.
The scene and materials are named correctly, in Latin. Scene and material libraries saved for V-Ray and Corona. All elements have their UVW map
Happy using!
