You are sharing a web scene layer or web scene that contains a point layer using a rotation order other than YXZ. The web scene viewer only supports a rotation order of YXZ.
The provided solution will select the layer in the contents pane:
- Right-click the layer and click Symbology to open the Symbology pane.
- Click the symbol to format the point symbol.
- On the Properties tab, in the 3D Behavior section, set the Rotation order to YXZ.
To be able to view your scene in the web scene viewer, all 3D point layers must have a rotation order of YXZ. For more information on symbolizing feature layers, see Symbolize feature layers.
