I don't know what metis is, but dcx files replace existing files in the game. The dcx file will usually be inside a folder in the zip like /parts/ for weapon model replacements.

Modengine2 is the best way to load these types of mods. Extract modengine2 and place the folders and files from the mod zip into /modengine2/mod/, then run launch_eldenring.bat.

That launches the game, and replaces any game files with their modded versions in that /mod/ folder.

I hope it doesn't conflict with the mod launcher, but probably the mod launcher is using modengine2 already. It's just helping you by placing things in the right folders and keeping track of what files belong to what mod or something.

Yeah the mod launcher is using modengine2, it appears to just be a user friendly interface. Okay so I just have to set up the folders properly and hopefully it will work even without specifically loading it in the launcher. Thanks.

Sorry for the notification, so I've tried this with a ragdoll mod but it does not change anything in game. Any idea why that may be?

Yeah, I'm trying to use some of KRDCD's dark souls armor model mods, and it's not working... no idea why.

Are you supposed to put the mods into the "modengine2" folder or what, bc i put it in"ModEngine-2.0.0-preview3-win64\mod"
