Assistance Required with Color and Lighting Issues

I am encountering an issue with my project workflow and lighting setup. The project was originally created in Vectorworks and exported as a Cinema 4D (C4D) file, which I then imported into Twinmotion.

The specific problems I am facing are as follows:

  1. When switching the quality settings in Twinmotion from Medium to High, the colors of the materials, including the floor, appear incorrect, and certain areas, such as the floor, become unnaturally dark.
  2. In Lit mode, the light does not properly pass through the glass panes, which affects the visibility and realism of the scene. However, when I enable Path Tracer mode, the light behaves as expected and passes through the glass.

I suspect the issue might be related to the materials or lighting configurations during the import/export process. Could you provide guidance on resolving these issues to ensure the colors and lighting remain consistent across quality settings and modes?
