Matinee had an awesome feature of animating a float or vector material parameter.
Sequencer is different and doesn’t have the same tracks available.
Does anyone know how to animate materials in Sequencer?
No one knows? Matinee used to have lots of properties available to add to an actor track. Sequenced doesn’t seem to have anything but visibility, animation and transform.
I would also like to know this!
Anyone have any suggestions?
You should use Event track in Sequencer. Then in Level blueprint you add custom events and change whatever you want there from sound to material properties, anything. And then you just add a keyframe to Event track and give it the same title as your custom event.
