… just a little Sunday afternoon Enscape practice inspired by an old but cool Bond movie 
(to get this underwater-like environment I used this “horseshoe”-shaped thing (pic #3) and an underwater photo from the web, which I projected as texture on it then, which thankfully worked pretty well and also fast and simple)
pic 4 is a render of the same model, done with Shaderlight - there the used underwater HDRI simultaneously acts as a shadowcatcher as well which makes such a thing much easier - especially regarding the lighting and the reflections and this weird environment geometry is not necessary so. I’m looking forward to the time when this is possible in Enscape too 
Note: no idea why above is stated Revit as used modeling software somehow? - I used SketchUp
