RHINO > SKETCHUP

I have a Rhino file sent to me from a Landscape Architect. I had it converted to SketchUp, but the asset materials aren’t visible in Enscape (tethered to SketchUp). Does anyone know how I can convert the Rhino File so that the asset materials appear in SketchUp/Enscape?

See attached showing assets in white, no materials.

If they are still groups or preferably components, then you may find the related assets and re-assign them to the components.

I think also there is a Sketchup plugin that converts similar groups to components ( I vaguely remember, as it was used to convert tree leaves to components)
