Problem with the textures of the imported object

Hello

I have such a problem!

  1. I imported the building from the Xplane 11 flight simulator into a blender.

  2. From the blender I exported the building with the texture to the MSFS2020 extended gITF 2.0 flight simulator

  3. In the MSFS2020 flight simulator, the texture of the building is not the same as in the blender, the texture is dark colors are dark I took a screenshot here: http://avd.cba.pl/msfs2020/screenshot/screenshot.jpg

  4. I made a test in a blender in the same project, next to the imported building, I made a new object on the right, similar to the imported one, and applied the same texture to it, then exported the building with the texture to the MSFS2020 extended gITF 2.0 flight simulator. And now the building I made, its texture is displayed correctly, I made a screenshot here: http://avd.cba.pl/msfs2020/screenshot/screenshot1.jpg

In my opinion, it results from the fact that in the imported building there are some parameters saved with it that I do not know where to look in the blender and what should I change so that the textures are the same bright as in the building that I made in the image imported in the same project.

Where in the blender can I delete or reset saved settings for an imported object?
