Unable to share a web scene containing point cloud data from ArcGIS Pro

Description

When attempting to share a lidar dataset as a web scene from ArcGIS Pro 1.4, the following warning message is returned:

Warning:   
24078: Layer's data source is not supported.

Cause

Publishing a web scene containing point cloud data from ArcGIS Pro 1.4 is a known limitation. Scenes with lidar data type cannot be shared directly from ArcGIS Pro 1.4 to ArcGIS Online or Portal for ArcGIS.

Solution or Workaround

1. Create a scene layer package in ArcGIS Pro 1.4. Refer to the following document: Create Scene Layer Package.
2. Upload the created scene layer package to ArcGIS Online or Portal for ArcGIS, and publish as a hosted scene layer. Refer to the following document: Publish from a scene layer package.
3. Add the service URL of the published scene layer to the ArcGIS Online scene viewer. Refer to the following document: Add layers with a URL.

Note:
It is possible to publish a point cloud scene layer from ArcGIS Pro 1.4 to both ArcGIS Online and Portal for ArcGIS 10.5 by creating a scene layer package and manually uploading the point cloud scene layer. However, the point cloud scene layer cannot be displayed in the Portal for ArcGIS scene viewer due to a limitation of the ability of the scene viewer to render the point cloud data.
