Apple TV Player settings
This page details the Player settings specific to tvOS. For a description of the general Player settings, see Player.
You can find documentation for the properties in the following sections:
Icon
Use the Icon settings to customize the branding for your Apple TV app.
Apple TV images consist of between two and five layers. Unity provides two layers for Apple TV icons.
Note: For more information on layering images for Apple TV, see the Apple Developer documentation on Layered Images.
| Setting | Function |
|---|---|
| App icons | Build the custom icon that you would like to appear on your AppleTV home screen for each resolution (1280x768, 800x480, and 400x240). |
| Top Shelf icons | Build the custom icon that you would like to appear on the AppleTV top shelf for each aspect and resolution (4640x1440, 2320x720, 3840x1440, and 1920x720). |
Resolution and Presentation
Enable the Disable Depth and Stencil option to disable the depth and stencil buffersA memory store that holds an 8-bit per-pixel value. In Unity, you can use a stencil buffer to flag pixels, and then only render to pixels that pass the stencil operation. More info
See in Glossary.
Splash Image
In addition to the common Splash Screen settings, there are two additional settings for the tvOS platform:
Use the AppleTV (1x) and AppleTV (2x) properties to set Apple TV static splash screens.
Debugging and crash reporting
| Setting | Function |
|---|---|
| Enable Internal ProfilerA window that helps you to optimize your game. It shows how much time is spent in the various areas of your game. For example, it can report the percentage of time spent rendering, animating or in your game logic. More info See in Glossary (Deprecated) |
Enables an internal profiler which collects performance data of the application and prints a report to the console. The report contains the number of milliseconds that it took for each Unity subsystem to execute on each frame. The data is averaged across 30 frames. |
| On .Net UnhandledException | The action taken on .NET unhandled exception. The options are Crash (the application crashes hardly and forces tvOS to generate a crash report that can be submitted to iTunes by app users and inspected by developers), Silent Exit (the application exits gracefully). |
| Log Obj-C Uncaught Exceptions | Enables a custom Objective-C Uncaught Exception handler, which prints exception information to console. |
| Enable Crash Report API | Enables a custom crash reporter to capture crashes. Crash logs are available to 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 via CrashReport API. |
Other Settings
This section allows you to customize a range of options organized into the following groups:
- RenderingThe process of drawing graphics to the screen (or to a render texture). By default, the main camera in Unity renders its view to the screen. More info
See in Glossary - Identification
- Configuration
- Optimization
- Logging
- Legacy
Rendering
Use these settings to customize how Unity renders your game for Standalone platforms.
| Setting | Function | |
|---|---|---|
| Color Space | Choose which color space should be used for rendering: Gamma or Linear. See the Linear rendering overview for an explanation of the difference between the two. |
|
| Auto Graphics API | Disable this option to manually set the graphics APIs. This option is enabled by default, and includes Metal. | |
| Color Gamut | You can add or remove color gamuts for the iOS platform to use for rendering. Click the plus (+) icon to see a list of available gamuts. A color gamut defines a possible range of colors available for a given device (such as a monitor or screen). The sRGB gamut is the default (and required) gamut. When targeting recent tvOS devices with wide color gamut displays, use DisplayP3 to utilize full display capabilities. Use Metal Editor Support as a fallback for older devices. |
|
| Metal Editor Support | Enable this option to use the Metal API in the Unity Editor and unlock faster ShaderA small script that contains the mathematical calculations and algorithms for calculating the Color of each pixel rendered, based on the lighting input and the Material configuration. More info See in Glossary iteration for targeting the Metal API. |
|
| Metal API Validation | Enable this option when you need to debug Shader issues. Note: Validation increases CPU usage, so use it only for debugging. |
|
| Metal Write-Only Backbuffer | Allow improved performance in non-default device orientation. This sets the frameBufferOnly flag on the back buffer, which prevents readback from the back buffer but enables some driver optimization. | |
| Force hard shadows on Metal | Enable this option to force Unity to use point sampling for shadows on Metal. This reduces shadow quality, which should give better performance. | |
| Memoryless Depth | Choose when to use memoryless render textures. Memoryless render textures are temporarily stored in the on-tile memory when rendered, not in CPU or GPU memory. This reduces memory usage of your app but you cannot read or write to these render textures. Note: Memoryless render textures are only supported on tvOS, tvOS 10.0+ Metal and Vulkan. Render textures are read/write protected and stored in CPU or GPU memory on other platforms. |
|
| Unused | Never use memoryless framebuffer depth. | |
| Forced | Always use memoryless framebuffer depth. | |
| Automatic | Let Unity decide when to use memoryless framebuffer depth. | |
| Multithreaded Rendering | Enable this option to use multithreaded rendering. This is only supported on Metal. | |
| Static BatchingA technique Unity uses to draw GameObjects on the screen that combines static (non-moving) GameObjects into big Meshes, and renders them in a faster way. More info See in Glossary |
Enable this option to use Static batching. | |
| Dynamic BatchingAn automatic Unity process which attempts to render multiple meshes as if they were a single mesh for optimized graphics performance. The technique transforms all of the GameObject vertices on the CPU and groups many similar vertices together. More info See in Glossary |
Check this box to use Dynamic Batching on your build (enabled by default). | |
| Compute Skinning | Enable this option to use DX11/ES3 GPU compute skinningThe process of binding bone joints to the vertices of a character’s mesh or ‘skin’. Performed with an external tool, such as Blender or Autodesk Maya. More info See in Glossary, which frees up CPU resources. |
|
| Graphics Jobs (Experimental) | Enable this option to instruct Unity to offload graphics tasks (render loops) to worker threads running on other CPU cores. This is intended to reduce the time spent in Camera.Render on the main thread, which is often a bottleneck. Note: This feature is experimental. It may not deliver a performance improvement for your project, and may introduce new crashes. |
|
| Normal Map Encoding | Choose XYZ or DXT5nm-style to set the normal map encoding. This setting affects the encoding scheme and compressionA method of storing data that reduces the amount of storage space it requires. See Texture Compression, Animation Compression, Audio Compression, Build Compression. See in Glossary format used for normal mapsA type of Bump Map texture that allows you to add surface detail such as bumps, grooves, and scratches to a model which catch the light as if they are represented by real geometry. More info See in Glossary. DXT5nm-style normal maps are of higher quality, but more expensive to decode in shaders. |
|
| Lightmap Encoding | Choose Low Quality, Normal Quality, or High Quality to set the lightmapA pre-rendered texture that contains the effects of light sources on static objects in the scene. Lightmaps are overlaid on top of scene geometry to create the effect of lighting. More info See in Glossary encoding. This setting affects the encoding scheme and compression format of the lightmaps. |
|
| Lightmap Streaming Enabled | Enable this option to load only the lightmap mipmaps as needed to render the current game Cameras. This value applies to the lightmap textures as they are generated. Note: To use this setting, you must enable the Texture Streaming Quality setting. |
|
| Streaming Priority | Set the lightmap mipmap streaming priority to resolve resource conflicts. Unity applies these values to the light map textures as it generates them. Positive numbers give higher priority. Valid values range from –128 to 127. |
|
| Enable Frame Timing Stats | Enable this option to gather CPU/GPU frame timing statistics. | |
Identification
| Setting | Function |
|---|---|
| Bundle Identifier | Enter the provisioning profile of the game or product you are building. The basic structure of the identifier is com.CompanyName.ProductName. This structure may vary internationally based on where you live, so always default to the string provided to you by Apple for your Developer Account. Your ProductName is set up in your provisioning certificates. This value appears as CFBundleIdentifier in the associated info.plist file. See the Apple developer documentation on CFBundleIdentifier to learn more. Note: This is shared between iOS, tvOS and Android. |
| Version | Enter the release-version-number string for the bundle (for example, 4.3.6). This appears as CFBundleShortVersionString in the associated info.plist file.See the Apple developer documentation on CFBundleShortVersionString to learn more. |
| BuildThe process of compiling your project into a format that is ready to run on a specific platform or platforms. More info See in Glossary |
Enter the build number for this version of your app. This appears as CFBundleVersion in the associated info.plist file.See the Apple developer documentation on CFBundleVersion to learn more. |
| Signing Team ID | Enter your Apple Developer Team ID. You can find this on the Apple Developer website under Xcode Help. This sets the Team ID for the generated Xcode project, allowing developers to use the Build and Run functionality. An Apple Developer Team ID must be set here for automatic signing of your app. For more information, see Creating Your Team Provisioning Profile. |
| Automatically Sign | Enable this option to allow Xcode to automatically sign your build. |
Configuration
| Setting | Function | |
|---|---|---|
| Scripting Runtime Version | Choose which .NET runtime to use in your project. For more details, see Microsoft’s .NET documentation. | |
| .NET 3.5 Equivalent (Deprecated) | A .NET runtime which implements the .NET 3.5 API. This functionality is deprecated, and should no longer be used. Please use .NET 4. | |
| .NET 4.x Equivalent | A .NET runtime which implements the .NET 4 API. This API is newer than .NET 3.5, and as such, it offers access to more APIs, is compatible with more external libraries, and supports C# 6. This is the default scripting runtime. | |
|
Scripting BackendA framework that powers scripting in Unity. Unity supports three different scripting backends depending on target platform: Mono, .NET and IL2CPP. Universal Windows Platform, however, supports only two: .NET and IL2CPP. More info See in Glossary |
Choose the scripting backend you want to use. This setting is not enabled for tvOS. | |
| API Compatibility Level | There are two options for API compatibility level: .NET 4.0, or .NET Standard 2.0. Tip: If you are having problems with a third-party assembly, you can try the suggestion in the API Compatibility Level section below. |
|
| C++ Compiler Configuration | Choose the C++ compiler configuration used when compiling IL2CPPA Unity-developed scripting back-end which you can use as an alternative to Mono when building projects for some platforms. More info See in Glossary generated code. This setting is not enabled for tvOS. |
|
| Use on Demand Resource | Enable this option to use on-demand resources. This setting has no effect for tvOS. |
|
| Accelerometer Frequency | Define 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. | |
| Camera Usage Description | Enter the reason for accessing the cameraA component which creates an image of a particular viewpoint in your scene. The output is either drawn to the screen or captured as a texture. More info See in Glossary on the tvOS device. |
|
| Location Usage Description | Enter the reason for accessing the location of the tvOS device. | |
| Microphone Usage Description | Enter the reason for accessing the microphone on the tvOS device. | |
| Mute Other Audio Sources | Enable this option if you want your Unity application to stop Audio from applications running in the background. Otherise, Audio from background applications continues to play alongside your Unity application. | |
| Requires Persistent WiFi | Enable this option to require a Wi-Fi connection. tvOS maintains the active Wi-Fi connection while the application is running. | |
| Allow downloads over HTTP (nonsecure) | Enable this option to allow downloading content over HTTP. Default and recommended is HTTPS. | |
| Supported URL schemes | A list of supported URL schemes. To add new schemes, increase the value of the Size property and then set a reference to the Asset to load in the new Element box that appears. |
|
| Target SDK | Select which SDK the game targets. The choices are Device SDK and Simulator SDK. Note: Be sure to select the correct SDK. For example, if you select the Device SDK but then target the Simulator in Xcode then the build will fail with a lot of error messages. |
|
| Target minimum tvOS Version | Defines the minimum version of tvOS that the game works on. | |
| Architecture | Choose which architecture to target. This setting is not enabled for tvOS because it changes automatically depending on the value set for the Target SDK property. | |
| Require Extended Game Controller | Enable this if your app requires a game controller. For more information, see the Apple Developer documentation on Game ControllersA device to control objects and characters in a game. See in Glossary. |
|
| Active Input Handling | Choose how you want to handle input from users. | |
| Input Manager | Use the traditional Input window. | |
| Input System (Preview) | Use the Input system. The Input System is provided as a preview packageA preview package is in development and not yet ready for production. A package in preview might be at any stage of development, from the initial stages to near completion. See in Glossary for this release. To try a preview of the Input System, 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 is outside of your .NET compatibility level. In order to understand what is going on in such cases, and how to best fix it, try following these suggestions:
- Install Reflector for Windows.
- Drag the .NET assemblies for the API compatibility level you are having issues with into Reflector. You can find these under
Frameworks/Mono/lib/mono/YOURSUBSET/. - Drag in your 3rd-party assembly.
- Right-click your 3rd-party assembly and select Analyze.
- In the analysis report, inspect the Depends on section. The report highlights anything that the 3rd-party assembly depends on, but that is not available in the .NET compatibility level of your choice in red.
Script Compilation
| Setting | Function | |
|---|---|---|
| Scripting Define Symbols | Set custom compilation flags. For more details, see the documentation on Platform dependent compilation. | |
| Additional Compiler Arguments | Add 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, press the ‘+’ button. To remove an entry, press the ‘-’ button. When you have added all desired arguments, click the Apply button to include your additional arguments in future compilations.The Revert button resets this list to the most recent applied state. |
|
| Suppress Common Warnings | Disable this setting to display the C# warnings CS0169 and CS0649. | |
| Allow ‘unsafe’ Code | Enable 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 | Disable this setting 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 documentation. |
|
| Enable Roslyn Analyzers | Disable this setting to compile user-written scripts without Roslyn analyzer DLLs that might be present in your project. | |
| Use Roslyn Reference Assemblies | Disable this setting to the compiler not to skip compilation reference assemblies when the metadata of the assembly does not change. | |
Optimization
| Setting | Function | |
|---|---|---|
| Prebake CollisionA collision occurs when the physics engine detects that the colliders of two GameObjects make contact or overlap, when at least one has a Rigidbody component and is in motion. More info See in Glossary Meshes |
Enable this option to add collision data to Meshes at build time. | |
| Keep Loaded Shaders Alive | Enable this option to prevent shaders from being unloaded. | |
| Preloaded Assets | Set 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. |
|
| AOT compilation options | Additional options for Ahead of Time (AOT) compilation. This helps optimize the size of the built tvOS player. | |
| Strip Engine Code | Enable code stripping. This setting is only available with the IL2CPP Scripting Backend. Most games don’t use all necessary DLLs. With the Strip Engine Code option enabled, you can strip out unused parts to reduce the size of the built player on tvOS devices. If your game is using classes that would normally be stripped out by the option you currently have selected, you’ll be presented with a Debug message when you make a build. |
|
| Managed Stripping Level | Choose how aggressively Unity strips unused managed (C#) code. | |
| Normal | Remove unreachable managed code to reduce build size and .NET/IL2CPP build times. | |
| Aggressive | Run UnityLinker in a less conservative mode than normal, reducing code size even further than what Normal can achieve. However, this additional reduction may come with tradeoffs. For more information, see ManagedStrippingLevel. | |
| Script Call Optimization | Choose how to optionally disable exception handling for a speed boost at runtime. See iOS Optimization for details. | |
| Slow and Safe | Use full exception handling (with some performance impact on the device when using the Mono scripting backend). | |
| Fast but no Exceptions | No data provided for exceptions on the device (the game runs faster when using the Mono scripting backend). Note: Using this option with the IL2CPP Scripting Backend does not impact performance; however, using it can avoid undefined behavior on release builds. |
|
| Vertex Compression | Set vertex compression per channel. For example, you can enable compression for everything except positions and lightmap UVs. Whole MeshThe main graphics primitive of Unity. Meshes make up a large part of your 3D worlds. Unity supports triangulated or Quadrangulated polygon meshes. Nurbs, Nurms, Subdiv surfaces must be converted to polygons. More info See in Glossary compression set per imported object overrides where vertex compression is set on objects. Everything else obeys these vertex compression settings. |
|
| Optimize Mesh Data | Enable this option to remove any data from Meshes that is not required by the Material applied to them (such as tangents, normals, colors, and UVs). | |
Logging
Select what type of logging to allow in specific contexts.
Check one box that corresponds to each Log Type (Error, Assert, Warning, Log, and Exception) when running scripts (ScriptOnly) , all the time (Full), or never (None).
Legacy
Enable the Clamp BlendShapes (Deprecated) option to clamp the range of Blend Shape weights in SkinnedMeshRenderers.
