How do you get the Set Matte effect to work on a Grade Layer that has the effect Blur on it?
I've been trying to solve this problem for the past few days...
I have a plane (1) which is acting as a mask. I have a few other planes, a text layer and a grade layer with the blur effect on it and I have applied the SET MATTE effect on all of those and used the plane (1) as the source layer, Alpha as the matte source mode and subtract for blend.
All of the planes and text layers get hidden behind the plane (1) which I want. However, the grade layer with the blur effect on it does not. I want to be able to hide the grade layer with the blur on it as well.
Any help would be hugely appreciated as I've ran into multiple dead ends on this one.
