Hi,
After creating the Symbology of feature layer ("Points Of Interest", a Simple Point Layer) in ArcGIS Pro using Global Scene , the Scene containing this feature layer is shared and published to the ArcGIS Enterprise Portal. P.S. The symbology inside the layer "Points Of Interest" can be viewed in the Global Scene of ArcGIS Pro Environment. (Please refer to attached images : ArcGIS Pro-Symbology-1 to 4.png)
Then, the Scene is viewed by using Scene Viewer on the ArcGIS Enterprise Portal. However, not all of the symbology is well display, only can view Stair & Lobby symbology icon of the "Points Of Interest" feature layer... (Please refer to attached images : ArcGIS Portal-Scene Viewer-1 to 4.png)
May you please point out any setting that I've missed or set wrongly.
Thank you!
