• 2D
• Analysis
• Cache Server
• Colors
• External Tools
• GI Cache
• UI Scaling
• Custom package preferences

Navigating the Preferences window

Use the search box to filter the list of settings categories, and highlight keywords in the details pane on the right.

General

General preferences allow you to customize working in Unity overall.

Propiedad:		Función:
Auto Refresh		Enable this setting to update Assets automatically as they change.
¿Debe mostrarse el proyecto anterior al inicio?		Enable this setting to always load the previous Project at startup.
Compress Assets on Import		Enable this setting to automatically compress Assets during import.
Disable Editor Analytics (Pro solamente)		Enable this setting to stop the Editor automatically sending information back to Unity.
Show Asset Store search hits		Enable this setting to show the number of free/paid Assets from the Asset Store in the Project Browser.
Verify Saving Assets		Enable this setting if you wish to verify which Assets to save individually on quitting Unity.
Script Changes While Playing		Choose Unity’s behavior when scripts change while your game is running in the Editor.
	Recompile And Continue Playing	Recompile your scripts and keep running the Scene. This is the default behaviour, but you might want to change it if your scripts rely on any non-serializable data.
	Recompile After Finished Playing	Defer recompilation until you manually stop your Scene, avoiding any interruption.
	Stop Playing And Recompile	Immediately stop your Scene for recompilation, allowing you to quickly restart testing.
Editor Theme		Choose which skin to use in the Unity Editor. This is only available for Plus and Pro Unity subscriptions.
	Personal	Use the light grey background with black text.
	Professional	Use the dark grey background with white text.
Editor Font		Select which font to display in the Unity Editor. The default font is Inter.
Enable Alpha Numeric Sorting		Enable this setting to display a button in the top-right corner of the Hierarchy window, which toggles between Transform sort (the default) and Alphanumeric sort.
Enable Code Coverage		Enable this setting to access the interface for the code coverage data that Mono exposes. Code coverage lets you see how much of your code is executed when it is run. It’s normally associated with automated unit tests, but coverage data in Unity can be gathered at any time when the Editor is running. For more information, see documentation on Coverage API.

2D

Use the Max Sprite Atlas Cache Size (GB) preference to set the maximum size of the Sprite Atlas cache folder. Whenever possible, Unity keeps the size of this folder below this level.

Analysis

The Analysis preferences let you define settings for the Profiler.

Propiedad:	Función:
Frame Count	Choose how many frames to display in the Profiler window.
Remember last recording state	Save and load the recording state between Profiler sessions.
Default recording state	Choose whether recording is enabled or disabled when the Profiler begins.

Cache Server

Any time an Asset changes, Unity automatically re-imports it. Setting up a Cache Server drastically reduces the time it takes to import Assets. You can set up a Cache Server using remote hosting or stored on your local computer.

Propiedad:	Función:
New Projects default asset pipeline	Select the default asset pipeline for new Projects.
Active version	Displays the current asset pipeline version.
Asset Pipeline v1 (deprecated)
Cache Server Mode	Define the Cache Server mode. Local: Use a local Cache Server on this computer. The preferences for Local storage appear. Remote: Use a Cache Server hosted on a remote computer. The preferences for Remote hosting appear. By default the Cache Server is disabled.
Asset Pipeline v2
Cache Server Default Mode	Define whether the Cache Server is enabled or disabled by default. You can override this per Project in the Unity Editor settings.
Default IP address	Set the default IP address for the Cache Server to use. You can override this per Project in the Unity Editor settings.
Check Connection	Click this button to attempt to connect to the remote Cache Server.

Remote hosting

These preferences are only available when Use Cache Server is set to Remote.

Propiedad:	Función:
IP Address	Enter the IP address of the dedicated cache server that an administrator set up.
Check Connection	Click this button to attempt to connect to the remote Cache Server.

Local storage

These preferences are only available when the Use Cache Server is set to Local.

Propiedad:	Función:
Maximum Cache Size (GB)	Specify the maximum size in gigabytes for the Cache Server on this computer’s storage. The minimum size is 1GB. The maximum size is 200GB. The default cache size is 10GB.
Ubicación actual de la caché.	Enable this option to specify a location where you want to store the cache.
Cache Folder Location	Click the Browse button to specify a location for the cache.
Cache size is …	Message displaying the current size of the cache. Before clicking the Check Cache Size button, this appears as Cache size is unknown. After clicking the button, the calculated cache size appears in the message.
Check Cache Size	Click this to find out how much storage the Local Cache Server is using. This operation can take some time to complete if you have a large project.
Clean Cache	Delete the contents of the cache.
Cache Folder Location	Displays the current cache folder location.

Colors

The Colors preferences allow you to choose the colors that Unity uses when displaying various user interface elements.

External Tools

The External Tools preferences allow you to set up external applications for scripting, working with images, and source control.

Propiedad:	Función:
External Script Editor	Choose which application Unity should use to open script files. Unity automatically passes the correct arguments to script editors it has built-in support for. Unity has built-in support for Visual Studio (Express), Visual Studio Code, Xamarin Studio, MonoDevelop and JetBrains Rider.
Generate all .csproj files.	Enable this setting to generate all .csproj files.
Add .unityproj’s to .sln	Enable this setting to add UnityScript (.unityproj) projects to the generated solution (.sln) file. This is enabled by default for MonoDevelop and Xamarin Studio, and disabled by default for Visual Studio (Express) and Visual Studio Code.
Editor Attaching	Enable this setting to allow debugging of scripts in the Unity Editor. If you disable this option, you can’t attach a script debugger to Unity to debug your scripts.
Ubicación actual de la caché.	¿Qué aplicación debería usar Unity para abrir archivos de imagen?
Revision Control Diff/Merge	Choose which application you want Unity to use to resolve file differences with the Asset server. Unity detects these tools in their default installation locations (and checks registry keys for TortoiseMerge, WinMerge, PlasticSCM Merge, and Beyond Compare 4 on Windows).
JDK Installed with Unity (recommended)	See Android environment setup.
Android SDK Tools Installed with Unity (recommended)	See Android environment setup.
Android NDK Installed with Unity (recommended)	See Android environment setup.
Gradle Installed with Unity (recommended)	This option is enabled by default. Unity installs Gradle tools under Unity/Hub/Editor/[EditorVersion]/PlaybackEngines/AndroidPlayer/Tools/gradle. If you manually install Gradle tools in another location, you can disable this option and click the Browse button to select the correct installation folder. For more information about using Gradle in Unity, see Gradle for Android.
Stop Gradle daemons on exit	Enable this option so that when you close the Editor, Unity stops Gradle. If you are using Gradle to build multiple Android Projects at the same time, disable this option as it might cause your other builds to fail.
Maximum JVM heap size, Mbytes	Set the maximum Java heap size for building.
Keystores Dedicated Location	Choose the location for Keystores.

GI Cache

The Global Illumination (GI) system uses a cache on each computer to store intermediate files used to pre-compute real-time Global Illumination. All projects on the computer share the cache.

Propiedad:	Función:
Maximum Cache Size (GB)	Use the slider to set the maximum GI cache folder size. Unity keeps the GI cache folder size below this number whenever possible. Unity periodically deletes unused files to create more space (deleting the oldest files first). This is an automatic process, and doesn’t require you to do anything. Note: If the current Scene is using all the files in the GI cache, increase your cache size. Otherwise, resource-intensive recomputation occurs when baking. This can happen when the Scene is very large or the cache size is too small.
Ubicación actual de la caché.	Enable this option to allow a custom location for the GI cache folder. By default, the GI cache is stored in the Caches folder. All Projects share the cache folder. Tip: Storing the GI Cache on an SSD drive can speed up baking in cases where the baking process is I/O bound.
Cache Folder Location	Click the Browse button to specify a location for the cache.
Cache compression	Enable this option to allow Unity to compress files in the GI cache and reduce the size of the generated data. The files are LZ4-compressed by default, and the naming scheme is a hash and a file extension. The hashes are computed based on the inputs to the lighting system, so changing any of the following can lead to recomputation of lighting: - Materials (Textures, Albedo, Emission) - Lights - Geometry - Static flags - Light Probe groups - Reflection probes - Lightmap Parameters Tip: If you need to access the raw Enlighten data, disable Cache Compression and clean the cache.
Clean Cache	Use this button to clear the cache directory. It is not safe to delete the GI Cache directory manually while the Editor is running. This is because the Editor creates the GiCache folder when it starts and maintains a set of references to those files. The Clean Cache button ensures that the Editor releases all references to the files on disk before they are deleted.
Cache size is	Displays the current size of the cache.
Cache Folder Location	Displays the current cache folder location.

UI Scaling

The UI Scaling preferences let you define how to scale UI text and icons in the Unity Editor.

Propiedad:	Función:
Use default desktop setting	Enable this setting to use your computer’s default settings for scaling UI text and icons.
Current scaling	Displays the current scaling value.
Use custom scaling value	Override the scaling value.

Custom package preferences

Some Asset Store or Unity packages add their own custom preferences to the Preferences window. Generally these use the package name as the preferences category. In this example, you can see the Cinemachine package preferences:

For information about a specific package’s preferences, see the documentation for that package. This section contains documentation for standard Unity preferences only.
