Applying Materials to imported Sketchup model in Revit

  • So I have a Revit model that my designer wants to use for visualization. They've got a sketchup model of the site.

    He's gone thru the process of cleaning up the sketch up model and and assigning layers to everything. In Revit under the imported objects you can apply materials to each layer of the sketchup model, but when Enscape is started all of the sketchup surfaces show up as just white.

    Is this something that Enscape doesn't allow?

    Thanks in advance.
