How can I change the opacity of a sprite? [paper2d]

I can’t find any sort of material editor in the interface. Is there a way to do it?

There are some provided Paper2D materials that you can use. If you set your sprite’s material to TranslucentUnlitSpriteMaterial, adjusting the sprite’s color alpha will change opacity.

Thanks, Is there a way to access it in real time? I changed the defaultmaterial to take an opacity scalar. But I can’t work out how to get it back in blueprint as a dynamic material that can be altered during run time.

Get a reference to the sprite you want to change then drag off of it and type set sprite color then change the alpha value.
