I wanted to check out some canned 3D data provided from a 3rd party. Its a scene layer package (.slpk). Works fine in Pro (v2.4.2). After failing to publish a Web Scene I attempted to use the instructions here: Publish hosted scene layers—Portal for ArcGIS | ArcGIS Enterprise. I don't seem to have the tickbox on step 7; "Check the Publish this file as a hosted layer box". Without that the portal just holds the layer package for me which isn't very useful. I couldn't find any other way of publishing a hosted scene layer.
The data I'm uploading is a sales promo dataset from a 3D imagery provider and you would assume it would be rock solid.
Any assistance would be much appreciated.
