I am trying to do vertical transformation using EsriReprojector, I have installed additional grid files from the FME downloads sections and pasted them into the installation folder. But I am not getting the desired result. Height is unaffected. I have read some other questions but not able to understand what should I provide in vertical transformation field. Right now it's set to None.
Solved
Why EsriReprojector is not able to do vertical transformation? what should be provided to vertical transformation field?

Hi @rishi1804,
The EsriReprojector is limited to the vertical transformations included with ArcGIS. According the Esri documentation at https://pro.arcgis.com/en/pro-app/latest/help/mapping/properties/pdf/geographic_transformations.pdf, ArcGIS only seems to include vertical transformations from the Newlyn vertical coordinate system to ETRS89 or EVRF2019.
