I need a 3D model of a chandelier within a crystal stairwell to be created for a client presentation. I’ll provide the plans for the stairwell and the chandelier to ensure accuracy. The model should be moderately detailed, highlighting key features of both the chandelier and the space while maintaining a realistic look. For the chandelier, the lighting needs to produce a bright and dazzling effect to emphasize its grandeur and impact within the stairwell.
