Transparent Billboard Behind The Model

Hi! I’m trying to make an item in my game and I want that this shining picture is behind it.

The first problem is that the picture isn’t that transparent anymore, as you can see in the second picture. I tried to change different settings and try to find an answer online, but I couldn’t get it to work. It looks fine inside the widgets tho… I also tried this with “Material Billboard”, and I was able to make it transparent, but it won’t able me to scale it up.

Another problem is that I can’t get the Billboard behind the 3D model. Every now and then it goes through a 3D model, when the object is rotating. Changing “translucency sort priority” doesn’t do anything.


Anyone?? I would like it to look like something like this in the game:


(Illustration picture)

Toast = 3D Model
Shining = Billboard, or anything else that is transparent, looking at the player and always behing the 3D Model

Why is it glowing toast? It’s a long story…
