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

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.
