Bug in textures

[Moisez]

Hello, I have a problem with the textures of my 3DSmax project with Corona render, at first, when I carried out the first rendering tests, my textures were normal as in the first photo, then when I opened the file today to continue working on the project The render is coming out with buggy textures, the seams of objects appearing and a strange texture, does anyone know what it could be?

There are some changes between the projects, for example different objects in the background. Maybe you made some other change, for example to some material or texture?
As the first step, try resetting Corona's render settings (Render Setup > Scene > Reset settings).

It seems that many objects in your "problem image" have issues with smoothing groups. Look at the walls, door, roof - their surface doesn't look flat anymore. Try to add smooth modifier with auto smooth activated on any problematic object and see if that fixes the issue.
