I want to create an opacity mask in matinee or in whatever which can be applied to my static mesh which slowly reveals the static mesh upon time interval.

Right now , I did work with matinee and “visibility track” which just toggles it “Visible” to “Non Visible” in a certain interval , i want to make it move smoothly revealing a certain part of mesh as timeline goes along.

You’ll need to edit the material.

  • Set it to be Translucent.
  • Create a Scalar Parameter called Opacity, and feed it into the Opacity output pin of the material.

In your blueprint

  • On Construct… Create a Dynamic Material Instance of the Meshes material and save it in a variable.
  • You can now use the Material Instance’s Set Scalar Parameter function to set the Opacity of the material.
