I know there isn't any perfect way to transfer a Revit model to Sketchup with all the materials but I recently found this tutorial on youtube. He separated each category in different views in Revit and transferred them to Sketchup so in the end it made it easier to apply materials to the model. He applied material to all of the glass in like one click around 07:35. I haven't tried this method, has anyone done anything similar to this?
