Material Interface Parameter in Niagara Not Updating in Packaged Version

In my project, I am using a material interface parameter in Niagara to update the color of my Niagara particles based on an image that’s downloaded from incoming data. When running the project in editor, I do not have any issues seeing these particles update in color, but when packaged, they do not update at all. Are there any settings or tricks that I need to do in order for this to work in a packaged version of UE 5.4?
