RVT Toolbox for ArcGIS Pro Not Generating Stats/Displaying?

[hert6585Milton]

Hi everybody, 

I recently upgraded to ArcGIS 3.6.0 and I am using the RVT toolbox for ArcGIS custom toolbox to generate some visualizations based on LiDAR DEMS. Since I've upgraded, the toolbox has stopped working. I've been trying a few of the basic visualizations like hillshade, slope, etc. but they don't seem to be generating statistics (and not displaying). On the other hand, the built in ArcGIS Hillshade seems to work okay, but I need the RVT toolbox options for my research. Help!

I have tried:

- fixing a broken database connection 

- running the Calculate Stats tool (won't let me export the raster layer, 'Failed to export the data.Python raster function's .updatePixels() method returned nothing.')

- upgrading my graphics driver

- restarting the program as well as my computer

- clean uninstalling/reinstalling arcgis entirely and reinstalling RVT toolbox from scratch

- Saving the DEM as a TIFF, then clipping TIFF to my test extent, then trying the RVT raster functions

None of these options seem to work! Can anyone advise me on what to do?

My suspicion is that with the release of ArcGIS Pro 3.6.0, there were some changes to the various Python components that are not suitable for RVT for ArcGIS Pro.  The changes are - What's new in ArcGIS Pro 3.6—ArcGIS Pro | Documentation

I did pull up the RVT for ArcGIS Pro website and the Python package release history shows an update from July 4, 2025 (before the release of 3.6).  The GitHub site where one downloads the add-in seems to be several years old - GitHub - EarthObservation/rvt-arcgis-pro: ArcGIS Pro Relief Visualization Toolbox Raster Functions - so like I mentioned earlier, I suspect there are some key differences between 3.5 and 3.6 that cause the tool to not work as expected.
