I have a post process material with a simple scalar parameter. I have created a material instance of this material which I am using as a blendable in my global post process object. If I manually adjust the scalar parameter using the Material Instance editor everything works as I expect it to.
Now, I am trying to modify that parameter using matinee with a Float Material Parameter Track and I don’t see any results. For a test, I made a duplicate of this material, changed it to a surface material and applied it to an actor in the game and the parameter modifies perfectly using matinee. But the Post Process material still does not update.
Does anyone have any suggestions?
