Hello, if the rendered image is all black or all white, it is generally caused by the following three situations:

1. Rendering angle problem: If the viewing angle is just inside the wall or blocked by something, the rendered image will be all black. It is recommended to click on the guide view in the upper right corner to see the position of the blue dot and try to render in the middle of the gray area;

2. The viewing angle is stuck in the wall, turn on the camera clipping, reduce the camera value or push the lens forward and then render;

3. There is no light source in the floor plan: It will be dark without doors, windows and lights. It is necessary to appropriately supplement the light of the current space. It is recommended to place the fill light on the rendering interface in the middle of the room and change the brightness for rendering.
