Twinmotion identifying Existing parts of the project as the same material when Imported from a Revit phasing project

Hello,

I work at a residential remodeling firm. We have been using a collaborate revit file so that multiple people in the company can work on it at once. We also have been using phases in revit to distinguish between existing, demolition, and new construction.

When doing this we have run into problems rendering our views in Twinmotion. The exising parts of the projects don’t show up the way we want them to, all show up as one material even if it’s not the case in Revit. We can only assign different materials to the New Construction parts of the project.

Does anyone have any helpful tips or tricks to get revit Phasing work with Twinmotion.
