Property Description
Default is Full Screen Sets the app window to the full-screen native display resolution, covering the whole screen. This mode is also known as borderless full-screen. Unity renders the app content at the resolution set by a script, or the native display resolution if none is set and scales it to fill the window. When scaling, Unity adds black bars to the rendered output to match the display aspect ratioThe relationship of an image’s proportional dimensions, such as its width and height.
See in Glossary
to prevent content stretching. This process is called letterboxing.
Run In Background Indicates whether to keep the game running (rather than pausing) if the app loses focus.
Allow Fullscreen Switch Indicates whether to allow default OS full-screen key presses to toggle between full-screen and windowed modes.
Transparent Swapchain Indicates whether to set AlphaMode on the swap chain to DXGI_ALPHA_MODE_PREMULTIPLIED.

This setting is used only for UWP projects that use the XAML build type. By enabling this setting, you can compose Unity content with other XAML content in your application.

For more information, see PlayerSettings.WSA.transparentSwapchain.

Orientation

Choose the game’s screen orientation from the Default Orientation drop-down menu:

Property Description
Default Orientation Specifies the screen orientation the application uses.
Portrait The application uses portrait screen orientation where the bottom of the application’s window aligns with the bottom of the device’s screen.
Portrait Upside Down The application uses portrait screen orientation where the bottom of the application’s window aligns with the top of the device’s screen.
Landscape Right The application uses landscape screen orientation where the right side of the application’s window aligns with the bottom of the device’s screen.
Landscape Left The application uses landscape screen orientation where the right side of the application’s window aligns with the top of the device’s screen.
Auto Rotation The screen can rotate to any of the orientations you specify in the Allowed Orientations for Auto Rotation section.

 Allowed Orientations for Auto Rotation

Use the Allowed Orientations for Auto Rotation section to specify which orientations the application supports when you set Default Orientation to Auto Rotation. This is useful, for example, to lock the application to landscape orientation but allow the user to switch between landscape left and landscape right.

This section is visible only when Default Orientation is set to Auto Rotation. Enable each orientation by checking its box in this section:

Property Description
Portrait Indicates whether the application supports portrait screen orientation where the bottom of the application’s window aligns with the bottom of the device’s screen.
Portrait Upside Down Indicates whether the application supports portrait screen orientation where the bottom of the application’s window aligns with the top of the device’s screen.
Landscape Right Indicates whether the application supports landscape screen orientation where the right side of the application’s window aligns with the bottom of the device’s screen.
Landscape Left Indicates whether the application supports landscape screen orientation where the right side of the application’s window aligns with the top of the device’s screen.

Splash Image

Above the common Splash Screen settings, the Player Settings settings allow you to specify splash images for the Universal Windows PlatformAn IAP feature that supports Microsoft’s In App Purchase simulator, which allows you to test IAP purchase flows on devices before publishing your application.

Windows Splash settings for the Universal Windows platform.

Windows Holographic

Use these settings to customize the holographic splash image for Mixed Reality applications.

Windows Holographic Splash settings for the Universal Windows Platform.
Windows Holographic Splash settings for the Universal Windows Platform.

Set a Holographic Splash Image to appear during startup. This image appears for five seconds (or until the app finishes loading).

Tracking Loss

A Mixed Reality headset needs to build world-locked coordinate systems from its environment to allow holograms to stay in position. Tracking loss occurs when the headset loses track of where it is (can’t locate itself) in the world. This leads to a breakdown in spatial systems (spatial mapping, spatial anchors, spatial stages).

When this happens, Unity stops rendering holograms, pauses the game, and displays a notification. You can customize the notification image that appears by enabling the On Tracking Loss Pause and Show Image property, and then selecting the image to display with the Tracking Loss Image property.

For more information, see Recommended settings for Unity.

Overwrite background color

While your application initializes, UWP shows a Splash screen that appears before the Made with Unity Splash screen. It’s best practice to match the UWP Splash screen background to the Splash screen image because it’s more visually appealing. The default color is black.

To overwrite the UWP specific Splash screen background color:

  1. Go to Player Settings > Splash Screen and enable Overwrite Background Color.
  2. Choose a color from the Background Color selector.

If you overwrite the default background color, Unity changes the color value in the application manifest. If you are using the XAML application type, Unity also sets the color value in the initial XAML page.

Other Settings

This section allows you to customize a range of options organized into the following groups:

Rendering

Use these settings to customize how Unity renders your game for the Universal Windows Platform.

Rendering settings for the Universal Windows Platform.
Rendering settings for the Universal Windows Platform.
Property Description
Color Space Choose which color space Unity uses for rendering: Gamma or Linear. For more information, see Linear rendering overview.

Gamma: Gamma color space is typically used for calculating lighting on older hardware restricted to 8 bits per channel for the frame buffer format. Even though monitors today are digital, they might still take a gamma-encoded signal as input.

Linear: Linear color space rendering gives more precise results. When you select to work in linear color space, the Editor defaults to using sRGB sampling. If your Textures are in linear color space, you need to work in linear color space and disable sRGB sampling for each Texture.
Auto Graphics API Indicates whether to manually pick and reorder the graphics APIs. By default this option is enabled, and Unity uses Direct3D11.
Static Batching Uses Static batching.

For more information, see Draw call batching.
Dynamic Batching Uses dynamic batching (enabled by default).

For more information, see Draw call batching.

Note: Dynamic batching has no effect when a Scriptable Render Pipeline is active, so this setting is only visible if the Scriptable Render Pipeline Asset Graphics setting is blank.
Sprite Batching Threshold Controls the maximum vertex threshold used when batching.
GPU Compute Skinning Indicates whether to use DX11/DX12/ES3 GPU skinning.
Graphics Jobs Offloads graphics tasks (render loops) to worker threads running on other CPU cores. This option reduces the time spent in Camera.Render on the main thread, which can be a bottleneck.
Lightmap Encoding Defines the encoding scheme and compression format of the lightmaps.
You can choose from Low Quality, Normal Quality, or High Quality.
HDR Cubemap Encoding Defines the encoding scheme and compression format of the HDR Cubemaps.
You can choose from Low Quality, Normal Quality, or High Quality.
Lightmap Streaming Uses Mipmap Streaming for lightmaps. Unity applies this setting to all lightmaps when it generates them.

Note: To use this setting, you must enable the Texture Streaming Quality setting.
Streaming Priority Sets the priority for all lightmaps in the Mipmap Streaming system. Unity applies this setting to all lightmaps when it generates them.
Positive numbers give higher priority. Valid values range from –128 to 127.
Frame Timing Stats Allows Unity to gather CPU/GPU frame timing statistics. Use this option with the Dynamic ResolutionA Camera setting that allows you to dynamically scale individual render targets, to reduce workload on the GPU. More info
See in Glossary
camera setting to determine if your application is CPU or GPU bound.
Use Display In HDR Mode (Windows Only) Allows the game to automatically switch to HDR mode output when it runs. This option works only on displays that support this feature. If the display doesn’t support HDR mode, the game runs in standard mode.
Swap Chain Bit Depth Selects the number of bits in each color channel for swap chain buffers. You can select Bit Depth 10 or Bit Depth 16. The option to choose bit depth only becomes available when you enable HDR Mode.

For more information on bit depth, see the Scripting API page for D3DHDRDisplayBitDepth.
Virtual Texturing Enable this option to reduce GPU memory usage and texture loading times if your Scene contains many high resolution textures.

For more information, see Virtual Texturing.

Note: The Unity Editor requires a restart for this setting to take effect.
Shader precision model Controls the default precision of samplers used in shaders. For more information, see Shader data types and precision.
360 Stereo Capture Allows Unity to capture stereoscopic 360 images and videos. When enabled, Unity compiles additional shader variants to support 360 capture (currently only on Windows OSX). When enabled, enable_360_capture keyword is added during the Stereo RenderCubemap call. This keyword is not triggered outside the Stereo RenderCubemap function.

For more information, see Stereo 360 Image and Video Capture.

Configuration

Configuration settings for the Universal Windows Platform.
Configuration settings for the Universal Windows Platform.
Property Description
Scripting Backend The scripting backend determines how Unity compiles and executes C# code in your Project. This setting defaults to IL2CPP for Universal Windows Platform and can’t be changed.
API Compatibility Level Choose which .NET APIs you can use in your project. This setting can affect compatibility with third-party libraries. However, it has no effect on Editor-specific code (code in an Editor directory, or within an Editor-specific Assembly Definition).

Tip: If you are having problems with a third-party assembly, you can try the suggestion in the API Compatibility Level section below.
.Net Framework Produces larger builds and any additional APIs available are not necessarily supported on all platforms. Choose this option when using libraries that access APIs not included in .NET Standard 2.0. Compatible with the .NET Framework 4 (which includes everything in the .NET Standard 2.0 profile as well as additional APIs).

For more information, see Referencing additional class library assemblies.
.Net Standard 2.1 Produces smaller builds and has full cross-platform support.
IL2CPP Code Generation Defines how Unity manages IL2CPP code generation.
Faster runtime Generates code optimized for runtime performance. This setting is enabled by default.
Faster (smaller) builds) Generates code optimized for build size and iteration. This setting generates less code and produces a smaller build, but may reduce runtime performance, especially for generic code. Use this option when faster build times are important, such as when iterating on changes.
C++ Compiler Configuration Chooses the C++ compiler configuration used when compiling IL2CPP generated code.

Note: This property is disabled for the Universal Windows Platform because it’s chosen in the generated Visual Studio project.
Use incremental GC Uses the incremental garbage collector, which spreads garbage collection over several frames to reduce garbage collection-related spikes in frame duration.

For more information, see Automatic Memory Management.
Assembly Version Validation Indicates whether Mono validates types from a strongly-named assembly.
Allow downloads over HTTP Indicates whether to allow downloading content over HTTP. The options are Not allowed, Allowed in Development builds only, and Always allowed. The default option is Not allowed due to the recommended protocol being HTTPS, which is more secure.
Accelerometer Frequency Defines how often to sample the accelerometer. If you choose Disabled, then no samples are taken. Otherwise, you can choose from 15Hz, 30Hz, 60Hz and 100Hz frequencies.
Active Input Handling Chooses how to handle input from users.
Input Manager (Old) Uses the traditional Input settings.
Input System Package (New) Uses the Input system. This option requires you to install the InputSystem package.
Both Use both systems side by side.

API Compatibility Level

You can choose your mono API compatibility level for all targets. Sometimes a third-party .NET library uses functionality that’s outside of your .NET compatibility level. To understand what’s going on in such cases, and how to best fix it, try following these suggestions:

  1. Install ILSpy for Windows.
  2. Drag the .NET assemblies for the API compatibility level that you are having issues with into ILSpy. You can find these under Data/MonoBleedingEdge/lib/mono/YOURSUBSET/.
  3. Drag in your third-party assembly.
  4. Right-click your third-party assembly and select Analyze.
  5. In the analysis report, inspect the Depends on section. The report highlights anything that the 3rd-party assembly depends on, but that’s not available in the .NET compatibility level of your choice in red.

Script Compilation

Script Compilation settings for the Universal Windows Platform.
Script Compilation settings for the Universal Windows Platform.
Property Description
Scripting Define Symbols Sets custom compilation flags.

For more details, see Platform dependent compilation.
Additional Compiler Arguments Adds entries to this list to pass additional arguments to the Roslyn compiler. Use one new entry for each additional argument.
To create a new entry, click Add (+). To remove an entry, click Remove (-).

When you have added all desired arguments, click Apply to include your additional arguments in future compilations. Click Revert to reset this list to the most recent applied state.
Suppress Common Warnings Indicates whether to display the C# warnings CS0169 and CS0649.
Allow ‘unsafe’ Code Enables support for compiling ‘unsafe’ C# code in a pre-defined assembly (for example, Assembly-CSharp.dll).
For Assembly Definition Files (.asmdef), click on one of your .asmdef files and enable the option in the Inspector window that appears.
Use Deterministic Compilation Indicates whether to prevent compilation with the -deterministic C# flag. With this setting enabled, compiled assemblies are byte-for-byte identical each time they are compiled.

For more information, see Microsoft’s deterministic compiler option.
Enable Roslyn Analyzers Indicates whether to compile user-written scriptsA piece of code that allows you to create your own Components, trigger game events, modify Component properties over time and respond to user input in any way you like. More info
See in Glossary
without Roslyn analyzer DLLs that might be present in your project.

Optimization

Optimization Settings for the Universal Windows Platform.

Property Description
Prebake Collision Meshes Adds collision data to Meshes at build time.
Keep Loaded Shaders Alive Indicates whether to prevent shaders from being unloaded.

For more information, see Shader Loading.
Preloaded Assets Sets an array of Assets for the player to load on startup.
To add new Assets, increase the value of the Size property and then set a reference to the Asset to load in the new Element box that appears.
Managed Stripping Level Chooses how aggressively Unity strips unused managed (C#) code. The options are Minimal, Low, Medium, and High.
When Unity builds your app, the Unity Linker process can strip unused code from the managed DLLs your Project uses. Stripping code can make the resulting executable significantly smaller, but can sometimes accidentally remove code that’s in use.

For more information about these options and bytecode stripping with IL2CPP, see ManagedStrippingLevel.
Vertex Compression Sets vertex compression per channel. This affects all the meshes in your project.
Typically, Vertex Compression is used to reduce the size of mesh data in memory, reduce file size, and improve GPU performance.

For more information on how to configure vertex compression and limitations of this setting, see Compressing mesh data.
Optimize Mesh Data Enable this option to strip unused vertex attributes from the mesh used in a build. This option reduces the amount of data in the mesh, which can help reduce build size, loading times, and runtime memory usage.

Warning: If you have this setting enabled, you should remember to not change material or shader settings at runtime.

See PlayerSettings.stripUnusedMeshComponents for more information.
Strict shader variant matching If a shader variant is missing, the editor uses the bright pink error shader whilst displaying an error message in the Console.
Texture MipMap Stripping Enables mipmap stripping for all platforms. This strips unused mipmaps from Textures at build time. Unity determines unused mipmaps by comparing the value of the mipmap against the Quality Settings for the current platform. If a mipmap value is excluded from every Quality Setting for the current platform, then Unity strips those mipmaps from the build at build time. If QualitySettings.masterTextureLimit is set to a mipmap value that has been stripped, Unity will set the value to the closest mipmap value that has not been stripped.

Stack Trace

Select which type of stack trace logging to allow in specific contexts.

Stack Trace settings for the Universal Windows Platform.
Stack Trace settings for the Universal Windows Platform.
  • Select your preferred stack trace method by enabling the option that corresponds to each Log Type (Error, Assert, Warning, Log, and Exception) based on the type of logging you require. For example:
    • ScriptOnly: Logs only when running scripts.
    • Full: Logs all the time.
    • None: No logs are ever recorded.

See stack trace logging for more information.

Legacy

Enable Clamp BlendShapes (Deprecated) to clamp the range of blend shape weights in SkinnedMeshRenderers.

Legacy settings for the Universal Windows Platform.
Legacy settings for the Universal Windows Platform.

Publishing Settings

Use these settings to customize building your Universal Windows app. These options are organized into the following groups:

Unity stores these settings in the Package.appxmanifest file when creating a Visual Studio solution for the first time.

Note: If you build your project on top of the existing one, Unity doesn’t overwrite the Package.appxmanifest file if it’s already present. That means if you change any of the Player settings, you need to check Package.appxmanifest. If you want to regenerate Package.appxmanifest, delete it and rebuild your project from Unity.

For more information, see Microsoft’s documentation on App package manifest.

Supported orientations from Player Settings are also populated to the manifest (Package.appxmanifest file in Visual Studio solution). On Universal Windows Apps, Unity resets the orientation to the one you used in the Player settings, regardless of what you specify in the manifest. This is because Windows itself ignores those settings on desktop and tablet computers.

Tip: You can always change supported orientations using Unity scripting API.

Packaging

Think of each unique Scene file as a unique level. In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces. More info
See in Glossary
. To include Scene Assets by default, use the Last required scene index setting. Assets in Scenes with a scene index above the Last required scene index are specified as streamable in the manifest file.
Last required scene index Enter the index number from the Scenes In Build list on the Build Settings window that corresponds to the last scene in that list that must be present in the game build. For an application to start, Unity requires any scene index at or less than the specified index. To require all files in the list, use the index of the last scene in the list.
Scenes with a greater scene index must include shared Assets for Scenes with a lesser index. The order of scenes in the Build Settings dialog may be important to allow the application to locate the required assets.

Note: By default, the Streaming Install option is disabled, which means that this setting isn’t available. To make this property editable, enable the Streaming Install option first.

Certificate

Every Universal Windows App needs a certificate which identifies a developer.
