The ability to see dynamic, real-time reflections in the viewport has been in Nitrous for a while but not exposed to the user interface. A simple maxscript can enable this feature. I have uploaded a pair of macros to enable or disable it You'll find them on the "Maxscripts" page of the DAS web site. Just copy the 2 macros to your Macroscripts folder (wherever that may be), restart Max and follow the instructions for activating and using the macros as described in the screen capture images in the zip download. A sample of the dynamic reflections in use is included and shown below. This is just a quick feature enhancement to the viewports. More powerful scripts are out there to help wrangle Nitrous to your liking.
