Spark AR Studio

Changelog

To find out what's new in Spark AR Studio, check our release notes below. New versions are released every 2 weeks.

We often launch new features and make some big changes, so make sure to read these notes before upgrading.

Version v73 - Oct 14, 2019

New

  • Learn your way around in the Spark AR Studio Tour. The guided tour walks through essential parts of the interface and also shares the basics of building effects.
  • Add custom devices to the Simulator to easily test your effect. To add a custom device, select Preferences from the Spark AR Studio drop-down menu.
  • The maximum size of .arexport files — the files downloaded to your machine after exporting a project — is now 40MB.

    • Improved

  • Sample projects have animated images instead of static previews.
  • When you open a saved project, filters in the Viewport will be enabled or disabled in the same way they were when the project was last saved.
  • Assets imported from the AR Library no longer display as “scene” in the Assets panel. Instead, the name matches the original name of the asset.
  • Crash reports automatically appear after crashes and include a streamlined way to send a crash log.

    • SDK Changelog

  • Fix environment texture rotation in Physically-Based Material.

    • Version v72 - Sep 30, 2019

    New

  • Work on projects using multiple versions of Spark AR Studio. You’ll still be prompted to update to the latest version, but can disable these notifications. Find the different versions of Spark AR Studio you’ve downloaded in the main menu.
  • Create patches for the different emitter types (Line, Plane and Ring) in particle systems.
  • Access the target tracker in the Patch Editor.
  • Create patches to represent the Size, Scale, Rotation and Position properties of 2D objects. Patch functionalities that contradict 2D layout will be blocked.

    • The new Devices preference pane can be used to add custom devices to the set of devices available in the simulator. Devices can be specified by their screen resolution and texture compression method.
    • You can now add instructions to your project, to give people hints when they're using your effect in the camera.

    Improved

    • Import of duplicated textures is now supported. Identical files will be de-duplicated as part of the export flow, and the sizes in the export pane and the asset summary will reflect this.
    • The Asset Summary now contains a root Project node that indicates the full size of your packaged project. The sizes here are the sizes of the full export and the same as those given in the export panel. There's also an Other entry that contains the size of the data model, scripts, and any other files that contribute to your export sizes that aren't otherwise included in the asset summary. To fill-in the table with these sizes, you might need to to press the Compress All button.
    • Minor Asset Summary improvements:
      • The Asset Summary can be launched from the Project menu, rather than the View menu.
      • The ordering of download and unpacked (on-device) sizes has been swapped, to make them consistent with the Inspector.
      • The Compress All button is now disabled when the table is fully-populated.
    • An emission texture can now be specified for standard materials. It will be modulated with the existing emission color for rendering.
    • An alpha cutoff can now be specified for materials that support advanced options. This allows transparent areas with an alpha lower than the specified threshold (which was previously forced to be zero) to be masked out from rendering.
    • We've fixed alpha operations (blending, alpha test) that were incorrectly taking into account specular values for lit materials.

    Patch Editor Improvements

    Known Issues

    • When you import 3D objects, they are assumed to be using the unit that your AR Studio project is using (defined in project properties, cm by default). To get the correct sizing, you need to match the imported file to your project. Any scripts or shaders that specify a unit value may also require fixing as these values will now be different. We are working to improve this process by reading the exported units from the import file.
    • If you import a facemesh for distortion and it looks unexpected, check that the scale of the facemesh is correct.
    • Opening one of the sample projects, selecting the script object, and clicking either the "Edit" or "Reveal Script" button in the Inspector results in a message that the script is missing.

        • Global objects like 'textures', 'scene', 'materials', 'layers', 'faces'. Please use the reactive modules instead.
        • functions like 'init()', 'update()' or 'updateFaces()' won't work anymore. Please take a look at examples for reactive effects.
