Unity water layer separation

Question

Hey, I have a question about using the built in water in unity HDRP with Arcgis. Is it possible to get some sort of land layer mask so we could exclude part of the ocean?

Also is the implementation of simulated water on your roadmap for Arcgis unity?

I'm facing the same issues and would like to see a function where the Unitys HDRP water simulation can be used with esri.

Right now we're trying to use the built-in water in Unity HDRP 2023.1 with ArcGIS. We're trying to create some simple water physics like buoyancy and other effects and its working great but runs into a lot of visual problems when trying to integrate it with ArcGIS.

So our requirement for water in ArcGIS would be the possibility to use the in-built water that Unity provides in the HDRP.  Right now the problems are;

* Not being able to use the Global scene in ArcGIS because of the curvature. (Could be solved by using the Local scene and faking curvature with shaders)
* Unable to exclude landmass from the water volume.
* Unable to define coastlines, the water mask could be generated by ArcGIS
* Local scene clipping out parts of the world when it reaches the end of the map.

It would be great if the Local scene would be able to "loop" just like in the global scene because right now it just cuts off when you place the perimeter at the end of the map.

Right now we don't support masking tile image layer, only 3d object scene layer, building scene layer, integrated mesh layer and elevation layers. You will need to modify the original dataset in ArcGIS Pro.

For simulated water would you mind describing your requirements? We received a lot of feedback about water simulation so a water sample is on our plan.
