Stairs And Railling Invisible

[alapoe]

My stairs and railing suddenly become like a mirror. There is nothing wrong with the material, but when I tried other stairs, they all became like this. I don't know what's happening, I can't make my work cause all of the stairs and railing become invisible

Operating system used: Windows 29.0.1

It may be a Graphic Override or Renovation Filter that is changing the surface materials.

Just for future reference:

Another reason can be the "Schematic" setting for Stairs in the Model View Options Dialog.
