Troubleshooting

Head is detached from Body when animating in Sequencer

Start by re-exporting the head animation without head movement.

If the problem still persists, try disabling post-processing on the Face and Body:

In the World Outliner, select your Metahuman.
In the Details Panel, select the "Body" component of your Metahuman.
Check "Disable Post Processing".
Repeat steps 2-3 with the "Face" component of your Metahuman.
You may need to try different combinations of having Post Processing enabled and disabled on the "Face" and/or "Body" components.

Received a warning about Texture Pool size

In the Unreal Command Line, enter:

r.TextureStreaming = "2000"

NOTE:

The number may need to be greater than 2000 if you have a lot of textures in your level.
This is a temporary fix. The command will need to be run every time you restart your project.
