I've seen a lot of Fire Emblem styled facesets in RM projects. Are these rips or custom made ones? If they are custom made, are they complete pixel art projects or is there a program similar to FaceMaker that allows people to make them?

Wondering because I'm not a huge fan of FaceMaker, but my pixel art skills aren't good enough to do things from scratch.

well I've only seen two places where there have been Fe styled facesets, my game and that fr fangame, both of which where edited a ton and frankensprited a ton or completely made from some template that someone made just for his own use or something I'm not sure. But I'd say there is not a fe facemaker, otherwise it would suck.

If you want some facesets for your game I'd suggest nakamura:

Thank you and have a nice day!
