in esri UNREAL SDK 2.1.0 and UE5.4 trying to create an elevation layer from high resolution raster Geotiff elevation source. I have put in layers from 3Dtiles as local slpk packages but I cant seem to figure out how to get an .slpk packages out of ArcGIS Pro 3.5. Also is this only going to work if I have 3D and Spatial analyst modules licensed and active? I was assuming the most common (in my line of work) elevation format as a raster Geotiff would be easy to put in as a layer into the esri UNREAL SDK but am finding this one particularly difficult. I want to build super high resolution local scenes and output custom flyover animations with this as that would speed up our workflow considerably over more traditional animation efforts.
