Set Matte effect on a text layer does not pull in the mask from a Plane layer
I've got text moving right to left on a text layer, and I want it to fade out when it reaches the left side of the screen. To do this I've tried two methods, neither of which are producing the fade:
- In my composite shot I created a Plane layer and drew a shape with the mask tool. I feathered the mask, so when the text reaches it, the mask will create the fade effect. Going back to the Text layer, I added the Set Matte effect and selected my Plane layer as the source. This did not mask the text at all, and no amount of flipping selectors or controls was able to make the text fade out as it slides to the left.
- I did the same operations but this time tried to create the Plane layer in a separate composite shot. Again, no success.
Repeated viewings of help tutorials from a variety of users did not help. Can it be my Set Matte effect is simply not working? What's the fix?
