How to Animate Material Parameters in Level Sequencer:
How to make a material animatable:
1. Make your Material as usual.
2. With your material created as normal, inside the content browser, right click and create a "Material Parameter Collection"
I find it useful to name it "materialname_params"
3. Open the Material Parameter Collection and add as many parameters you would like to animate. To animate opacity, we will add a scalar parameter, and name it opacity
4. Go back into your original material, and add a CollectionParameter node inside your node graph
5. Select the node and inside the node details, select the created collection and the desired parameter
You can now use this node just like any other parameter within the node graph. A good way to understand the node is to use it just like a normal parameter.
SIDE NOTE
To animate opacity smoothly without reflections, change your material lighting mode to Surface TranslucencyVolume

How to animate the material:
1. Inside your level sequencer, click add and select "Material Parameter Collection Track"
2. Select your collection and parameters to animate within your level sequencer.
