[2020] How to butcher and process dead animals?

1. Press 'x' with a settler selected and right-click the target animal you want to kill.
2. You will see '____ remains' when the critter is killed. You can open the jobs menu and select the butcher job. Then click the remains. Someone with the butcher skill should come along and turn the remains into meat, bone, and hide (if applicable).

There is one issue where you cannot butcher anything that's stored, so try to keep animal remains out in the open so you can still apply the job. This is something I'm going to fix by adding a room to let you auto-butcher animals.

You can use the meat, bone, and hides for various blueprints. Hides can be turned into different leathers which are then, in turn, used for creating things like leather armor.

Also, not all entities have remains which you can butcher. For example, Ancients.

Hope that helps!
