This then writes off the cost of creating any required DDC data across the entire team. This is a network drive that all team members and build machines can read/write to. One of our strongest recommendations for teams in the same location is that they set up a shared DDC. Similarly, some samples are shipped with a DDC Pak for the same reason.įor Example: EngineDir/DerivedDataCache/Compressed.ddpįor Example: ProjectDir/DerivedDataCache/Compressed.ddp The DDC Pak contains derived data for all engine content, so you can start working without compiling shaders and so on.

If you download Unreal Engine from the Epic Games Store, the engine will come with a DDC Pak (.ddp). However, your project may also be set up to use a DDC Pak or Shared DDC. Local DDC: Derived data for your projects. Typically, you will have at least the following two caches:īoot DDC: Startup files that are loaded into memory to increase boot times.įor Example: ProjectDir/DerivedDataCache/Boot.ddc Storing these derived formats externally makes it possible to easily add or change the formats used by the engine without needing to modify the source Asset file. If the data is not found, then it is first generated, then asynchronously copied into the caches so it is available for you (and potentially your team) in the future.Ĭontent stored in the DDC is disposable, and can be regenerated at any time using the data stored in the. When the data is found, it is copied into the fastest local cache so that it is quicker to access next time. When a piece of derived data is needed, the fastest cache is checked first, then the next fastest, and so on, until the data is found. When assessing derived data, your system will do the following to determine how quickly it can access it: Instead it's kept in the Derived Data Cache (DDC).ĭepending on how your project and system are configured, there can be several DDC caches in a hierarchy that ranges from fast to slow. Before the Material can be rendered, the shader must be compiled for the platform the editor is running on.īecause the derived data is large, and at times may need regenerating, it is not checked into source control. (A simple example would be a Material that has a shader). Many Unreal Engine Assets require additional "derived data" before they can be used.
