Great, and why you didn't share your knowledge then? Uncook your game files to get the latest xmls you need. Create a helpful dir structure for your mod like modGwentArachasFix\Cooked & modGwentArachasFix\modGwentArachasFix\content (this was a mod I created that is only an xml fix) Copy the xmls you want to edit from the Uncooked dir, making sure to keep the directory structures of where the xmls live exactly the same to your mod's Cooked dir (xml files are already considered cooked) Edit your xmls files in the mod\Cooked dir as you wish. Once you are done editing you now need to generate a bundle, do this with wcc_lite and a command like "F:\Applications\Play\GOG Games\Witcher 3 Mod Tools\bin\x64>wcc_lite pack -dir=J:\Witcher3\Mods\modGwentArachasFix\Cooked -outdir=J:\Witcher3\Mods\modGwentArachasFix\modGwentArachasFix\content" This will create a blob0.bundle in the content dir you created in step 2. Then do something like:"F:\Applications\Play\GOG Games\Witcher 3 Mod Tools\bin\x64>wcc_lite metadatastore -path=J:\Witcher3\Mods\modGwentArachasFix\modGwentArachasFix\content" This will place a metadata.store in the same dir as your bundle Move the subdir modGwentArachasFix which contains content\ to your <Witcher Install dir>\mods\ and test your mod. Assuming your mod works, zip up and submit to the nexus. :smile:
