There’s a pretty easy fix for one of the biggest problems with the game’s graphics: the textures of the weapons and the way they reflect light.
As detailed in the post linked below, many of the game’s weapons are completely emissive, which means they aren’t affected by light sources or shadows. However, the metal textures on some weapons, like the Musofadi sword and the Handcannoneer barrel, do work correctly. This means it’s possible to change this for the other weapons too, hopefully without too much effort.
It is one of the details that has been requested for years. It is something that has been addressed in more recent models (Musofadi warrior and Ghazi raider in particular), but has not been changed retroactively for older models. I believe this is something that could be addressed in a minor patch, if they wanted to bundle it with a major patch that would be fine too. But it isn’t hard to fix.
