As the title says I’m trying to figure out how to use alpha channels or achieve a video mask effect.
I came across this post: https://answers.unrealengine.com/questions/116661/can-45-video-textures-support-alpha-channels.html
But it doesn’t seem to answer any questions. All it does is show the types of files compatible. One of the posters in that link talks about splitting the black and white channels, which I’ve done however they aren’t synced properly, and that seems to be a common problem with that approach. I’ve also attempted to use spritesheets / flipbooks, which give the desired effect, but for trying to use video, it is far too unweildy because of the ridiculous amount of files that you have to use.
I know this sort of thing is possible because Kite and Lightning have done it, or something like it with Senza Pezo like this:https://www.youtube.com/watch?v=lrq0KRbRk1U&t=182
I just can’t seem to figure out how they achieve it. Any help would be much appreciated.
