After effects noob here. I'm working on an animation where a ball falls through a hole. I created a Shape layer to use as the mask, but I can't get it to mask the ball layer.
I've also tried adding a mask directly to the ball layer, but it moves with the rest of the animation. Is there a way to turn the mask on and off without affecting the rest of the animation?
I found this post helpful: Preventing a Mask From Animating
- Create a comp size solid above your text layer.
- Apply the mask to the solid.
- Set the Track Matte setting of your text layer to
Alpha Matte.- The text layer will now adopt the alpha channel of the masked solid.
You can freely animate the text and mask independently.
I did not know the name of what I was trying to do. I needed to convert the mask layer into a Track Matte.
In these cases, I generally precompose the layer and apply the mask to the precomp (the layer is animating inside the precomp)
