Hidden Aether Pack for MCH
A texture replacement for the Machinist off-hand model, hiding it from view.
You’ll need FFXIV Textools https://www.ff14mods.com/ffxiv-textools. Search model ID 2099 in TexTools’ search under ‘weapons’, and export both A & B “normal” textures. Extract “Main Hand” to “Saved” in the saved directory of FFXIV Textools (or create that directory if it doesn’t already exist), overwrite the 2099 folder, and reimport as per.
