ProRes video with alpha channel for widget not working

Development Programming & Scripting UI

Animated a text sequence in After Effects to roll in when a pause widget is to be called. Video registers and plays fine in the Media Player. Import successful.

Widget BP is set up correctly to play animation, now here’s where I’m not sure where the disconnect is:

Material: no matter what variety of connections to color/opacity, it shows a white screen as the material. Widget designer reflects that preview in material, all white. Call widget while playing in viewport, ALL WHITE.

Apple ProRes plugin enabled, video exported as ProRes4444 (incl alpha channel)

An update for any other lost souls come across this post: Tried PNG sequence and getting the same results just in an all black screen :confused:

I use HAP Media plugin from standard plugins and use .mov with HAP encoding. Perfect alpha result and performance
