Release notes

Version 1.0.0 - June, 2022.

This page provides details about enhancements in ArcGIS Maps SDK for Unity version 1.0.0. It also lists this release's resolved issues, and known issues.

Updating from pre-release

The preset basemaps provided by ArcGIS Maps SDK for Unity require an API Key. If you are using a preset basemap, please make sure to set an API Key, or the basemap will fail to load and the ArcGIS Map will appear blank. See Known issues.

Learn more about using API Keys with ArcGIS Maps SDK for Unity here.

Issues resolved

• Tiles render inconsistently with multiple raster tile layers

  Summary: When there are more than eight raster tile layers visible in the viewport, tile composition becomes inconsistent. It is possible to have more than eight layers in your scene, but as soon as your viewport has more than eight raster tile layers displayed and there are camera and/or layer visibility changes, the issue occurs.

Enhancements

This section describes new features and improvements (what's new).

Editor mode support

You can view and edit the open scene live in the Scene view without the need to play the scene. This new feature allows you to place objects during editor time. You can disable it if you need to.

Increased spatial reference support

You can use any geographic coordinate system in global map type and any projected coordinate system in local map type. You have the option to specify the spatial reference of the ArcGIS Mapfor the layers you are going to add. Otherwise, the first layer loaded in the Viewport will determine the spatial reference.

Geometry API

A new geometry API is added to create geometries of type point, multipoint, polyline, polygon, envelope and enable spatial analysis. Geometries have a spatial reference, are Z and M aware, can be re-projected, and serialized to and from JSON.

Scene layer color, transparency and opacity support

Mesh colors can now be rendered. The transparency and opacity in the data are also reflected. Objects in scene layers, like trees, are rendered the same as they are with other Esri products.

Note: gltf material and the color information stored in the drawingInfo are not supported yet.

Mesh collision for raycasting

You can now enable mesh colliders for all layers.

OAuth 2.0

Support for access tokens and refresh tokens is added. Now you can set and get access tokens and refresh tokens.

Map Creator UI

The UI has been taken out from the Inspector window and named Map Creator UI. The new UI has a separate window and composed of components that are visible in the Inspector window. The Map Creator UI and the coponents are in sync, and you can see the changes in the corresponding components inside the Inspector window. when you make a change via the UI. You can also add a basemap and elevation source with a custom URL directly in the UI.

Known issues

• A basemap that fails to load will cause all layers in the ArcGIS Map to fail to display.

  Summary: If you are using a basemap that fails to load (for example, a preset basemap that requires an API Key, but no API Key is set) then the loading of the ArcGIS Map will be interrupted and it will appear blank. This also impacts the SDK samples that use a preset basemap.

  Workaround: Be sure to set an API key when using one of the preset basemaps.

• View state report propagated warning messages

  Summary: When you get the error message by using the view state report, propagated error messages are logged in the Console although it's not an error.

  Workaround: No workaround available.

• Layer with non-standard metadata loading, position, and LOD tile issue

  Summary: Some layers which render correctly in other Esri products are not rendered or rendered in an incorrect position in Unity, or with incorrect LOD tiles, although the service is in the supported layer type and spatial reference.

  Workaround: Case by case. If you have this issue, provide the detail via support.

• Changes on the component not reflected in the Map Creator UI.

  Summary: After making changes on the component, the Map Creator UI doesn't automatically updates with the new values.

  Workaround: Click on a different tab in the Map Creator UI to pull the new values from the component.

• The extent dimension values are incorrectly applied in the scene when the extent center is away from the Equator.

  Summary: When you set an extent in the area away from the Equator in an ArcGIS Mapwith a geographic coordinate system, the shape dimension is bigger than the values set for the extension.

  Workaround: No workaround available.

• One image tile layer is still visible in the Scene view window even after removing all during the editor mode.

  Summary: One image tile layer remains visible after removing all the image tile layers in the level.

  Workaround: Play the scene once or reload the scene.

• Setting opacity to scene layers doesn't make any effect.

  Summary: Opacity doesn't work if Unity material for the scene layer is opaque.

  Workaround: Change the scene layer material to the one that has transparency.

• Some part of integrated mesh scene layers flashes while navigating around the area

  Summary: When there is an elevation enabled in the scene, some part of the integrated mesh scene layers flashes.

  Workaround: Disable the elevation

• Tile flashing

  Summary: While navigating in the level, a few tiles flash occasionally when the elevation is enabled.

  Workaround: No workaround available.

• The layer management popup of the Map Creator UI stays visible.

  Summary: The layer management popup of the Map Creator UI stays visible even after clicking outside of it.

  Workaround: Click again on the ⋮ icon in the layers panel if you do not select any option from the popup window.

• The layer management popup of the Map Creator UI is covered by other Unity Editor windows.

  Summary: The layer management popup of the Map Creator UI is covered by other Unity Editor windows and not fully visible.

  Workaround: Adjust other window sizes to display all layer management options.

• An error is logged after removing a component.

  Summary: Modifying values in the Map Creator UI prints the error messages in the Console window after removing a component from the game object.

  Workaround: Readd the removed component from the Inspector window by clicking on the Add Component button. Note that the modified values in the Map Creator UI after removing the component and other values are not recoverable when the component has been readded.

• Not be able to deselect the original tiles or select new tiles while selecting a group of tiles in the Scene view

  Summary: While selecting a group of tiles in the Scene view by holding the Shift key, transform.localPosition assign attempt for ... error message logged in the Console window. Once the errors come up you cannot select anything else until you restart unity, attempting to press play will cause Unity to crash.

  Workaround: No workaround available.

• The default layer opacity is set to 0 instead of 1 in the ArcGIS Map component.

  Summary: When you add the first array element in the Layers section or the ArcGIS Map component, the default layer opacity is set to 0 instead of 1.

  Workaround: Manually change the layer opacity value to make it visible after adding the row.

• Adding a new layer array row in the ArcGIS Map component duplicates the layer that is already added

  Summary: When you add a new layer array element in the ArcGIS Map component, it duplicates the last row with their values.

  Workaround: Replace values with new values after adding the row.

• The Sample OAuth script used in the OAuthAPISample conflicts with the map component's authentication configuration list.

  Summary: The map component clears all existing configurations from the ArcGISAuthenticationManager and then adds its list from the UI. If another script adds a configuration, the map component will destroy it.

  Workaround: No workaround available.

• Generated normal maps have geometric patterns when the elevation is enabled.

  Summary: When an elevation is enabled, generated normal maps have geometric patterns and are visible on the surface.

  Workaround: No workaround available.

• The Android compile errors

  Summary: Compiling for Android fails with RenderTexture.Create failed: stencil texture format unsupported.

  Workaround: On Unity's Project window, navigate through Packages > ArcGIS MapsSDK for Unity > SDK > Renderer and open the ArcGISTerrainOcclusionRenderer.cs file. Then replace stencilFormat = UnityEngine.Experimental.Rendering.GraphicsFormat.R8_UInt, with depthStencilFormat = UnityEngine.Experimental.Rendering.GraphicsFormat.D32_SFloat_S8_UInt, at line 279.

• Map extent configuration via C# script being ignored

  Summary: The map extent configuration via the C# script is overwritten by the ArcGIS Map component, and doesn't make any effect in both the play mode and the editor mode.

  Workaround: Use the Map Extent section of the ArcGIS Map component to configure an extent.

• ArcGIS Hit Test Sample returns an incorrect number instead of the feature ID

  Summary: ArcGIS Hit Test Sample returns an incorrect number instead of the feature ID when clicking on a building while pressing the shift key during play mode.

  Workaround: No workaround available. This will be fixed in the next release.
