It’s usually safe to do per-bone stripping on server builds, where you delete bones that aren’t linked to gameplay. Animations often increase the performance demands of a build as a result, removing unnecessary animations server-side can improve performance a great deal. Some examples include:īecause server builds are headless, you might be able to exclude some animation-related code, such as character animation and bones that aren’t linked to gameplay, further reducing the resource requirements.

You can also strip other client-specific data to improve the performance of your build. Such automation might allow you to remove performance-heavy GameObjects and ensure the server is as lightweight as possible, resulting in reduced hosting costs. It’s possible to create automation workflows that selectively strip GameObjects depending on the build target. You can use third-party solutions, such as BuildStripper and Headless Builder, to manually strip Prefab and GameObject assets one by one. These callbacks should use the NetcodeHook class (see Boss Room’s Utilities package). Your server build can have a few NetworkBehaviours scripts to allow callbacks like OnNetworkSpawn. To avoid indexing issues with NGO, use script stripping with caution (and only strip as necessary). In general, you shouldn’t strip NetworkBehaviours in fact, NetworkBehaviours should always be the same between the client and server. By stripping a script, you can unintentionally create holes in the GameObject’s list of components, interfering with NGO’s indexing.

Netcode for GameObjects (NGO) relies on ()’s index position on a GameObject to know to which NetworkBehaviour it needs to route network messages. There are some indexing issues that arise when using Netcode for GameObjects (NGO) with asset stripping. Because Unity performs stripping operations at compile time, it’s easier to find compiler errors than runtime errors.

This would ensure you have no audio code running on your server. You can use the UNITY_SERVER option per script or per assembly to strip whole client-only assemblies.įor example, you might want to set all audio-specific code in an Audio assembly, then strip the Audio assembly from server build targets. You can strip scripts from a server build using the UNITY_SERVER scripting symbol. Script stripping involves removing client-only scripts from a server build. You should see a reduction in memory and CPU usage with the Dedicated Server build (compared to a build that includes client-side assets). See the Unity Build Settings documentation. The Dedicated Server build target automatically strips content the server doesn’t need at build time in addition to starting headless automatically. In Unity Editor version 2021 and later, you can use the Dedicated Server build target option. Server build stripping allows you to pack as many server instances as possible on your dedicated hosting, saving you money. You can do this by stripping the unnecessary assets from the server build at build time this way, the client-side assets aren’t included in memory when loading the executable. You can reduce the size of server builds and, as a result, save a lot of hardware resources by removing client-specific scripts and assets. Unlike client builds, server builds have no need for visuals, sounds, inputs, or anything related to a user's device like mobile notifications.
