Not sure how to translate "素材の良さが光ってる" as I don't know much about the character and her context (Yep, didn't play the game yet).
Translating word by word would be that she's a great material that shines or something.
Yeah, as Magmon1000 said she works as a cook in the game. I would probably translate to something like "you're made out of some good stuff" or something like that. A more literal translation possibility could be something like "the quality of your raw materials is shining through!"
