Make sure You don't already have the files in a folder higher on XIPivots priority list, maybe that could be taking priority over the ones you're changing.
Other than that there should be no reason why it's not showing up for you.
Remember also, I have all the weapons in separately named folders, you need to be copying them into either XIPivot or the games files starting at the "ROM" folder, not in this case, the Irradiance Blade folder.
So to replace the Greatsword go into the Irradiance Blade folder and copy the ROM folder.
Has anyone made or perhaps planning to make HD dats of the new mog bonanza lockstyles? Sapphire and diamond sets etc. Cool sets but look out of place with other HD armor pieces (using ashenbubs hd pack)
Another niche mod, but if you're someone who likes to do DAT replacements and haven't cleared the master trial, this is here.
Or if you're one of the lucky few to actually own one in game.
