Hm. I think I got it. But what I needed to do was open it in Effect Editor then click the arrow / Selection Tool in there, then click the vignette or solid layer I created in the record monitor to edit the effect. Although, that seems a bit wonky and slow because, what if I have so many layers that it becomes difficult to select one in the record monitor, thus not being able to edit the Paint layers?
Anything else I’m missing?
Thank you.
