Instead of looping or triggering via Blueprint, for those doing more renderer activity with Unreal, im just posting for the record:

Anyone that needs to link the VAT playback to a sequencer. So you can scrub through or retime it in the sequencer/line it up with other imported animation.

1. Add material to mesh fbx.
2. Add mesh fbx to sequencer.

In Sequencer on your Mesh;

3. Add StaticMeshComponent.
4. Add Material Parameters: Element 0.
5. Add Parameter: Display Frame.
6. Make Keyframes.

If someone knows how to do this in Unity, could you post? So people looking could find. Thank you!

Awesome!! Exactly what I needed

Yep! Good tip, and don't forget to deactivate the 'Auto Playback' option in the Instance material. If this option is activated, you can't animate this parameter in the sequence
