Particle Effects look different and movies aren't playing in a packaged game

I’m trying to package a project in UE4, and it mostly works fine after being packaged, however there are 2 problems: the particle effects I’ve made appear differently in the packaged result compared to the editor, and the movies that are packaged aren’t playing.

For example, this sword trail effect is a completely different color after being packaged, and the yellow blade doesn’t show up.

In other instances, the trails are the correct color, but they do not glow at all.

As for the movies, the only thing that shows up when they’re meant to play is a blank white screen. Any ideas on why all of this is happening?
