Hey, improvement idea, can we get something where we can have this happen:
This is a good idea, and not terribly difficult. I'll add it in a moment.
Not trying to be thick I swear but you do you clean fur (or feathers)?
Also, related, what building(s) do you use for feathers, chitin, scales, etc.
Fur is cleaned by going to the tannery and queuing up the 'clean and tan fur' task. Currently you may need to suspend the tanning task to make sure the skin item is free for fur-making.
Finally, have people had luck with this with genesis?
I believe Deon is cannibalizing this mod for Genesis, but at this point it won't be useable straight out of the .rar - you would need to edit all the Genesis creatures. It won't be incompatible, but since none of Genesis' creatures use the variations they won't drop the items required for fur/feathers/etc.
Also, what stockpiles do fur/feathers/etc go into?
Before processing, refuse. After processing, leather (or cloth, for wool and gut).
ETA: Using Genisis mod but tried it out with the basic version just to see if that was the issue. I did notice that with Genesis my chickens didn't drop feathers where they do in the basic (odd) but I still have had no luck actually making 'fur'.
If you haven't modified the creature raws yourself and aren't using the modified vanilla raws included in the .rar, you won't be able to produce any of the new materials. Try just extracting creature_tanmod_example.txt into your raws folder, it has a bunch of domestic creatures that use the new materials. If they don't work then something's wrong.
Also, and I apologize if there are more detailed instructions somewhere, but how do you actually make things out of feathers or fur (once I manage to get it)? I have some chicken feathers in the refuse bin but don't see anywhere to make feathered [object]?
Raw feathers use [HORN], I believe, so you would need to use the 'decorate with horn' job to make things out of them or whatever. It's cumbersome and silly but there's really no other way to go about it. Processed feathers/fur/hide/chitin are all leather items and can be used accordingly.
