Datasmith Direct Link for Revit in Unreal Engine 5 preserves your material changes by applying materials in a way that does not override existing ones. After linking your Revit file, manually reassign your custom materials in Unreal to ensure that they remain intact. Datasmith’s “Preserve Data” option allows you to maintain your customizations and avoid overwriting them. By using this approach, you can adjust materials as needed without having to wait for the Revit model to be completed.
