UMG: Anyway to use a sprite flipbook?

Hello there,

I’m confused because I’ve been able to add a simple flipbook to UMG and it worked (added to the viewport) then I’ve tried the next step (which is what I really need) assigning the UMG (with the flipbook) to a 3D widget but nothing shows up.

Nick: would it be possible to get an update on what is currently working and not working please ?
(I’m not sure if I’m doing something wrong or If there is no way it’s going to work)
