Apply mesh modification to layers

daicz — Tue, 05 Sep 2023 09:27:05 GMT

I don't understand the description.

I implemented the feature in UnrealEngine with blueprints, but I don't know how to implement it in Unity. Here is my attempt in Unity, unfortunately it fails

Can you tell me the correct code steps?

Thanks!

Hi, you just need to convert geometry to polygon and add it to the mesh layer. The code below works fine in Unity.

ArcGISPolygonBuilder pb = new ArcGISPolygonBuilder(ArcGISSpatialReference.WGS84());

pb.AddPoint(x1, y1);
pb.AddPoint(x2, y2);
pb.AddPoint(x3, y3);
pb.AddPoint(x4, y4);

ArcGISMeshModification mm = new ArcGISMeshModification((ArcGISPolygon)pb.ToGeometry(), ArcGISMeshModificationType.Clip);

layer.MeshModifications.Add(mm);

That's exactly what I want. Thank you very much!
