In the Content Browser, go to Add New and create a Material Parameter Collection, which can be found under the Materials & Textures advanced asset heading. In there, you can set up a custom scalar parameter and change the name and default value.

From there, drag the material parameter collection into the material of the object that you want to fade out. If the object has multiple materials you’ll have to do this for every material in the object. You’ll be able to select the parameter that you created in the details menu of the Material Parameter Collection, then plug the node into the opacity.

You can then drag the Material Parameter Collection into the Sequencer, select the parameter that you want to animate (in this case the opacity that you’ve plugged into the materials), and set your keys from 1 to 0. This should fade it out.

This is great, but I was wondering, how do you apply this to a Blueprint with a box collision with the On Component Begin Overlap? Sorry if it’s a dumb question, I’m a beginner and I’m trying to figure out how to fade out the opacity of an object while fading in another one. For example, in a first person setting, if the player walks over a very flat and wide collision box, that has to trigger one object to appear gradually and another to disappear. How do you do that on a Blueprint? So far I learned how to make an object move with a timeline event connected to a SetRelativePosition node. But I couldn’t find anything about opacity.
