Set Matte Effect Problem

naliniajda Posts: 2 Just Starting Out


So I'm making an animated object and I want it to be invisible on spesific area. I dont use mask because the mask will follow the movement of the object. I want it to be still (the invisible area), so I use the set matte effect. Unfortunately I'm facing some errors.

I followed these steps based on the video I watched:

  1. Create a plane layer, mask it to shape the desired area that I want to be invisible
  2. Apply the set matte to the moving object
  3. Set the source to the plane layer
  4. Change the blend to add

On the tutorial video I watched, the moving object will be invisible on the plane area. But in my case, the object is invisible even after it pass the plane area. Does anyone know how to fix this? Thank you
