I succesfully rendered 3D View of Vienna city centre as shown in this tutorial by underdark . I download trees point data in GeoJSON from OSM using Overpass API. Now I want to render the points as spheres that are elevated above the surface. However, I cannot find where in QGIS 3D Renderer settings can I define the height of the sphere. See screenshot provided.
I looked thru GIS Stack Exchange, Lutra Consulting webpage, Twitter feeds and other tutorials but I cannot find any answer. Anyone knows how to elevate the sphrere about ground?
