Looking for a landscape solution

[WalterWright]

Hello,

I started using the ArcGIS SDK in UE5. I've got to say I'm really impressed with the performance of the New York sample area.

Our goal for our project is to use the heightmap data from ArcGIS (and maybe some 3D buildings, if they exist in the area) but to use Unreal to enhance the visualizations. For instance, we want to replace the landscape textures with different ones from unreal especially for the roads which have the top view of cars on them and use the sweet nanite-based foliage from 5.1 when it gets out of preview. We also want to be able to deform the landscape for new construction projects as well as add or remove buildings, add some traffic, people, etc.

That being said, in looking for the forum and based on the examples in unreal, it appears that the entire areas are brought in as a procedural object and cannot be modified or turned into an unreal landscape. I was looking to verify that this is the case, and if so, is there a way to have more control in Unreal over the objects?

Thanks,

Darryl

Hi Darryl,

I think this would only be possible if the current terrain can be converted to a terrain mesh in Unreal. This is not possible and don't know if this will be possible in the near future. We were looking for this too and to remove buildings of existing layers you need to do this in the ArcGIS Online tools. Adding new objects is possible to do by integrating Datasmith plugin.
