Video Player -> Transparent Background -> Shadows

Unity Engine

Hello everyone !

Okay so this a really tricky one and I don’t even know if it possible.
Basically I’ve working on this fro a week now not finding any viable solution :

I have a video player in my Unity AR URP project. This player is playing a video with transparent background (the black is removed). What I want to achieve is, for example of a person is dancing in the video, to cast shadows of the person on the floor.
I know how to remove the background. I know how to cast shadows. But with URP even a transparent surface is cast as a 100% opaque texture, so basically my shadows are always squared because the VIDEO FRAME is casting shadows, not the person in it.

I hope I made myself understood.
Thanks !

I think that using alpha clip will fix this problem. It can be enabled in the graph inspector. This causes pixels below a certain alpha treshold to be discarded, which I believe will also prevent them from casting shadows.
