Screen-position aligned Sphere Mask?

Yup, its the same thing as using two component mask nodes, that function just contains them inside.

Try placing the ScreenPosition node and using that. if it doesn’t align correctly by default, try selecting the 2nd option in the drop down, I think its called viewportsize or viewportresolution or something.

I also forgot that you will have to subtract half of the difference in scale. so if X was multiplied by 2, it needs to offset by 1/2 first. I will be back later and I can try making an example using nodes if you are still messing with it.

So I tried structuring it, but I think I may have confused myself a bit on the structure. Here’s an image of what I have:

I’m getting a weird ellipses mask that expands outwards at a crooked angle, like this:
