I see the Chunk.getStructureStart(String), but it need the structure name. Chunk.getStructureReferences() can return a Map<>, but the references is hard to find the structure class... What should I do?

No more than two megabytes or so. My guess is that you're trying to include the /run and/or /build folders too.  Do not do that.

(And I assume that "commonnamespace" is not literally "commonnamespace" but something identifiable to your mod.)

That part can be achieved using some GLMs. You can just store the original loot generated. As for how to get it back to the player object, it's gonna take some crafty work with the server world.

Yeah that part went over my head because I let the four mods thing get in my head I was still trying to use the modid from each mod. Got it working now, just need to test more. Thanks again I knew it was in the ballpark but just could not see the resolution. all the mod tag groups are now under "resources\data\commonnamespace\tags\items\carnivore.json" in all four mods [and any other third party mods as well as datapacks] and then I do  something like loc = new ResourceLocation("commonnamespace", "carnivore"); tagwrapper = new ItemTags.Wrapper(loc); ingredientlist = Ingredient.fromTag(tagwrapper); goalSelector.addGoal(4, new TemptGoal(this, 1.2D, false, ingredientlist));
