Did I draw a picture with 3dmax? Can't you render it? Did the camera move? What should I do?

Usually the rendering is blocked by things, including the VR surface light source, and the rendering is also dark. It is also possible that the camera turned on manual cutting, the distance of manual cutting is beyond the scope of the scene model, and nothing can be rendered, or all the objects in the scene are seen by the camera. This is my guess. It's hard to judge without looking at the file.
