Getting media texture to play on skeletal mesh

Hi everyone. Newbie here.
I’ve worked in film Visual Effects for 12 years but am very new to using UnReal.

I’m currently attempting to set up a character asset we created for a series in UnReal using the film asset and all the animation libraries we developed. Hoping to make something of an ‘animation mixing desk’ for the character for a future project.

Running into some trouble with the face as the characters eyes and expressions are effectively a series of emojis (like Eve in Wall-E)

Does anyone know how I might go about getting a media texture to apply to a skeletal mesh? I’m able to get both h264 mp4’s and image sequences playing on a basic card, but haven’t been able to get them to play on the characters face.

Thanks!
