Known Issues

 

  • Issue with identical families disappearing from rendering
  • Changing the Atmospheric Height and View Distance of Aerial Perspective is not properly applied during RT CPU

  • In case you receive the below error when starting Revit after installation of V-Ray for Revit plugin, follow the steps to resolve it

    Section or group name 'userSettings' is already defined. This can not be defined multiple times. (C:\Program Files\Autodesk\Revit Architecture 2016\Revit.exe.config line 7)


    Follow these steps:
    1. Browse to the file mentioned in the brackets, save a backup copy of it and open it in a text editor.
    2. Delete repeated tags <sectionGroup name="userSettings"...</sectionGroup> and <userSettings>...</userSettings>. Make sure that only one copy for each of them is left in the file before saving it.
    3. Replace the file in the source location with the updated one.
