I'm fairly new to modding so I just need some help/guidance. I am trying to create a standalone version of Heolstor's Moonlight Greatsword to act as a replacer for DMGS in Elden Ring. I have found the chr files for Heolstor and unpacked all of them with WitchyBND, but none of them will open up in Blender so I'm not sure if I have to keep unpacking until I find something that Blender can use or if I'm just doing something wrong.
There might also be a standalone parts file corresponding to the weapon but I couldn't find anything in Smithbox and I doubt it exists since it isn't something equippable by the player.
