Hello, if it is a flat top or freely installed downlight, you can choose the spotlights in the decoration. In 3D or roaming mode, drag and place it with the mouse. If multiple placements are needed, hold the Shift key and drag to copy;

Under ceiling custom, to install downlights:

1. Please enter the ceiling custom, select from Electrical Appliance - Lighting - Downlight, and drag and place it on the layer;

2. You can right-click on the inner area(note: the inner layer does not support downlight installation for the time being), select Downlight Installation, select the style, and modify the distance.
