Recommended Unreal Engine Project Settings

This page lists the recommended Unreal Engine project settings for MetaHuman Animator.

Recommended IMG Media Cache Settings

MetaHuman Animator involves dealing with a lot of media, and the default project settings for media caching are ill fitting for it. Go to Project Settings > Plugins > IMG Media and set the following settings:

• “Use Global Cache” should be Enabled

• "Cache Threads" should be set to 4

• On minimum spec we recommend the Global Cache Size to be set to 2 GB

• On recommended spec we recommend the Global Cache Size to be set to 8 GB

Recommended UE Project Settings

To visualize animation results at the highest fidelity we would recommend going to Project Settings > Engine > Rendering and enabling the following settings:

• Engine - Rendering -> Use Unlimited Bone Influences

• Engine - Rendering -> Support 16-Bit Bone Index

Recommended RigLogic Settings

MetaHuman is native to UE in 5.8, but there are plugins that need to be turned on to expand the RigLogic functionality of MetaHuman characters in UE. Go to Project Settings > Plugin > RigLogic and use the following settings: 

Default DNA Config

Configure the default MetaHuman states for the entire project rather than individually.

• Under Layers set which layers to load:

  • Descriptor

  • Definition

  • Behavior

  • Geometry

  • GeometryNoBlendShapes

  • MLBehavior

  • RBFBehavior

• Set Max LOD and Min LOD per-platform overrides as needed (Mobile, Desktop, Console, and so on).

• Set Coordinate System Transform Policy (Preserve / Transform), Coordinate System, Rotation Sign, Rotation Sequence, Face Winding Order if your studio's source DNAs aren't in UE-native space.

Default RigLogic Configuration

Configure the default MetaHuman RigLogic states for the entire project rather than individually.

• Set Calculation Type per platform (Scalar, SSE, AVX, NEON,AnyVector).

• Set Floating Point Type per platform (Float, HalfFloat, Auto). 

  Auto resolves to Float on Desktop, HalfFloat elsewhere at cook time.

• Set Enable multi-thread ML Compute per platform.

• Toggle layer loads (LoadJoints, LoadBlendShapes, LoadAnimatedMaps, LoadMachineLearnedBehavior, LoadRBFBehavior, LoadTwistSwingBehavior).

Rendering Hardware Interface

Identity creation and Performance processing within the plugin are only supported in projects that use DirectX12 as their Default RHI. To verify this, go to Project Settings > Platforms > Windows and scroll down to the Targeted RHIs section.
