Dynamic Material for WidgetComponent

[alibatiste]

I have 2 effect in my material:

1. A billboard effect (always looking at the camera) (doesn’t need dynamic effect)
2. A pixel like disappear. (which need the dynamic effect).

I will try to make 2 materials. One on the 3D object or the billboard and an other for the 2D object. I this the solution i want but it’s a solution.
