Tiles in elevation.tpkg(s) render anomalies when zooming/panning.

Question

I started creating custom elevation tile packages (tpks's) about a year ago in hopes hopes packaging up my 3D layers for an offline mobile app featuring 3D bathymetry.

I'm able to create the lower-res custom elevation basemap tpkx and hi-res seafloor elevation tpkx layers with no issues. One issue that has greatly impeeded the project's progress is this ongoing issue the tpkx's functioning as expected for a day or two, then start exhibiting anomalies, like tiles becoming disconnected, large areas in the models disappear/reappear, the hi-res layer doesn't render in hi-res, and blocky extusions shoot in and out of the 3D model as I pan in zoom over the afficted areas.

I opened a ticket with Esri Support last July (2023) which addresses this issue which happens in both ArcGIS Pro and ArcGIS Scene Viewer. Esri Support hasn't come up with logical explaination, solution or workaournd despite our weekly meeting to discuss the topic. I've become quite well versed with the myrid of requirements that must be met when created custom elevation tile packages as well as many combinations that can be used to build and share tile layers accross the ArcGIS suite of products. So the usual culprits have been checked and checked twice, including the correct tiling schemes being used for elevation layers, tiling schemes have to match basemap, LERC compression requirements, coordinates reference systems match across all related layers. And usually if there's something amiss with a tpkx's configuration, ArcGIS Online or Scene Viewer is quick to let you know about it.

Could this be 'Z fighting'? The 3D layers control doesn't give me the option to move the hi-res layer to #1 priority in the list.
Could this GPU settings? I have new computer with NVIDIA 3060 GPU, so should do the job, however the settings may not be configured correctly.

Here's a few examples the anomalies the render when zooming/panning around the 3D model.

At some zoom levels, the 3D model disappears completly. 
Image 1a - 8035m above 3D terrain - No tiles in terrain model are visable (desite caching tiles a Level 20 in the scale)

Image 1b - 6045m above terrain, half the tiles in the area in focus display with the upside-down V wall at cut off point.

Image 1c - 4089m above terrain, more tiles missing, some show back up.

Image 2a - 4764m above terrain, shot taken over seemingly stable area of model.

Image 2b - 4279m above terrain - zoom in a few hundred meters and the entire area in focus show many missing tiles and walls shoot up everywhere.

Thanks for any feedback.

Hello John,

Thanks for the follow up. My ongoing Esri Support Case# is 03412481. I have a meeting scheduled with a new analyst this afternoon. I created a mspk from a functional scene in ArcGIS Pro and uploaded it to AGOL. I've created a group for ArcGIS Earth PM sharing in AGOL and shared the mspk with this group. I've also uploaded the mspk to my Dropbox and included the layers which were extracted using the Extract Package Geoprocessing tool to share with you.

I have gone through so many interations of creating and discarding layers while that my naming I"ve lost control of a logical naming convention system, the date/times of initial creation and the source of the sources. The mspk I shared with you failed to load to ArcGIS Earth Desktop this morning with the following message displaying in the application.

I have many more versions of my custom elevation layers, 2D layers and ArcGIS web services that I've created during my testing so trying to orgainze all this data to avoid cross contamination and false reporting of issues. Also, I'm trying to educate myself on ArcGIS Earth Desktop and Mobile processes to minimize user error when runnning tests.

Thanks again for your help!

Hi Matt,

Thank you very much for the detailed response. Your feedback is super helpful and was passed along to the ArcGIS Earth team yesterday. I will also engage with our Scene Viewer PM to better understand the limitations you are experiencing on the web side. Would you mind sharing a sample dataset with us? It will definitely help debug and determine why the order of. your layers within the MSPK are being changed. You can either upload directly to the forum or send me an email. My email is in the thread. I look forward to helping you find a resolution.

This is what my scene looks like in ArcGIS Scene Viewer and any app that requires a Scene to be hosted in AGOL before it can be imported into a 3D app template. I don't understand how how 3D apps are createrd if AGOL stips the elevation values from the scene? How is this possible? It's not a 3D scene anymore, this is the question I've been trying get answered for a about year now.
