I am trying to use ArcGIS Pro to create a 3D scene using an elevation surface (.tif) generated from drone imagery. The tif is projected and contains the elevation information, but I cannot get ArcGIS pro to accept the layer in 3D - only in 2D.
I can use the raster as an elevation surface in the scene: Right-click Scene in Contents Pane > Properties > Elevation Surface > ground > navigate to raster layer
But, the layer doesn't remain 3D when I publish the Web Scene to ArcGIS Online.
How do I use the raster as the actual 3D layer?
