A new mod has been released that adds some freckles to Sera and reduces shininess. The mod can be found on Nexus and, judging from screen shots, it’s a vast improvement.
I usually dislike appearance mods — it reduces characters down to only their appearance, which is something I find generally problematic. But since this actually corrects some uncanny-valley-esque issues with the game (namely that people sometimes look like they’ve been dipped in a light coating of vaseline), I’m supportive.
It’s also a great indication that the mod community is getting into gear and starting to produce, which is a good sign for everyone involved.
One note is that, as of yet, most mods can only replace textures, so caution should be used when installing new mods. This has led to some unexpected events, because textures can be reused over the game. So changing Sera’s textures could potentially change some areas of the game (as an example, changing makeup in the character generator sometimes changes the makeup used on NPCs). But there shouldn’t be any game breaking complications involved.
