Release notes

Support for Gaussian Splat Layers has been added in this release. Gaussian Splat Layers provide a new layer type for visualizing georeferenced Gaussian splat datasets in 3D scenes. Unlike traditional mesh or point cloud representations, Gaussian splats render reality capture data using collections of volumetric primitives that can preserve fine geometric detail, thin structures, vegetation, transparency, and reflective surfaces. Gaussian Splat Layers can be displayed alongside existing ArcGIS layer types and support integration with geospatial workflows that require accurate visualization of reality capture content. Initial support is provided for desktop platforms, with mobile support planned for a future release. For more information, see the Gaussian Splat Layers topic.

Point Cloud Scene Layers now support rendering and filtering APIs, providing greater control over the visualization of LiDAR and other point cloud datasets in Unity and Unreal Engine applications. Developers can render points using attributes such as RGB values, elevation, intensity, classification, or return information to create meaningful visual representations of their data. Filtering capabilities make it easy to focus on relevant subsets of points, such as ground surfaces, buildings, vegetation, or specific return types, helping reduce visual clutter and highlight important features. Additional controls for point size and color modulation further enhance visualization quality, improving readability and supporting more effective exploration and analysis of large-scale 3D point cloud datasets. For more information, see the Point cloud layer rendering and filtering topic .

Point Scene Layers now support 2D marker symbols, expanding the available symbology options beyond the 3D model symbols introduced in the previous release. Developers can visualize point features using billboarded picture and vector markers. Billboarded markers are rotated to "stand up" and always face toward you (toward the "camera") when you navigate through a scene. With support for these additional symbol types in simple, unique value, and class break renderers, Point scene layers provide increased flexibility for creating meaningful, attribute-driven visualizations while continuing to support realistic 3D model symbols and primitives. Current support focuses on billboarded marker symbols, and does not yet include draped or flat markers, text, or labels. For more information, see the Point Scene Layers topic.

This release introduces several improvements to 3D Tiles visualization, enabling more efficient rendering and better support for large-scale reality capture datasets. Enhancements to tile prioritization, level-of-detail selection, and culling behavior improve scene coverage while reducing memory usage, duplicate calculations, and rendering overhead. In addition, this release also adds support for dynamic attribution and copyright, enabling the display of 3D Tiles attribution and copyright information that varies depending on the map data requested for the current viewpoint. These enhancements improve the overall performance and usability of 3D Tiles layers, while providing developers with greater convenience in meeting data attribution requirements.

• BUG-000184113: Camera position set with “Align with View” is not preserved in deployed builds (Unreal Engine 5.7).

  Workaround: Reset the editor camera in the Pawn actor.

• Question on Esri Community: Collider offsets in rendered OSM 3D buildings.

  Summary: The collision mesh is not properly aligned with the corresponding rendered OSM 3D building, which can result in inaccurate collision detection or unexpected behavior when interacting with the 3D environment.

  Workaround: None available.

• Question on Esri Community: Unreal Engine editor may crash while creating a new ArcGISMap when using the Unreal Engine Simulation Blank project template.

  Summary: Opening the Unreal Engine Simulation Blank project template and then creating a new ArcGISMap causes the Unreal Engine editor to crash.

  Workaround: Remove the GeoreferencingSystem actor before creating a new ArcGISMap or instead use the Unreal Engine Blank project template under the Games Templates category. See Unreal Engine Templates Reference for more information about available templates.

  Summary: Gaussian splat layers are always rendered as opaque. Layer opacity cannot currently be adjusted.

  Workaround: None available.

• BUG-000186516: Flickering of 2D Markers in Point Scene Layers with Temporal Super Resolution (TSR)

  Summary: When rendering point scene layers that use 2D markers in Unreal Engine, users may experience noticeable flickering artifacts. This issue occurs when Temporal Super Resolution (TSR), Unreal Engine’s default temporal anti-aliasing technique, is enabled. The flickering is caused by the interaction between TSR’s frame-to-frame sampling and the occlusion logic for 2D markers, resulting in inconsistent visibility or “popping” effects as the camera moves or the scene updates.

  Workaround: To mitigate or eliminate the flickering, it is recommended to disable temporal anti-aliasing techniques such as TSR. Other non-temporal anti-aliasing methods (such as MSAA, if available) do not exhibit this flickering behavior with 2D markers.

  • Open your project’s rendering settings in Unreal Engine.
  • Locate the anti-aliasing method configuration.
  • Change the anti-aliasing method from TSR (or any temporal technique) to a non-temporal option, such as None or MSAA (if supported).
  • Save or apply the changes and restart the scene if necessary.
