Hello, I am trying to place a video material inside of a mixed reality application using the meta XR Plugin and Mixed reality utility tool kit. I have made sure the movies folder is packaged and the video worked fine when placed in the VR template (and I pacakged it to headset, it worked fine). However, When I palce the same video material inside the mixed reality map, and then package it, it shows up as just black cube, no video playing. Is this a thing with the mixed reality tool kit?
