It is able to set and view the Halo background in the Orbit 3DM Manage And Extract (please refer to halo_text_content manager.JPG).
However, it is not able to view it after uploading to the Orbit 3DM Publisher and Viewer (please refer to halo_text_publisher.JPG).
The support of Halo (Color and Transparency) on Labels of style "Text" is significantly important for clear visualization of Label in Viewer for all users at the same time. Also, this support can facilitate collaboration among different disciplines to view the data with Halo Label in a more easy and efficient way in the same platform.
It is grateful if Bentley Management Team could further review this idea and solve this issue.
