📋 About This Mod
NEW AS OF VERSION 1. 2: Loom added, and all machines are now configurable to either increase output quality or give a chance of double amount of standard quality items (25% chance with silver, 50% with gold, 100% with iridium). Also allows disabling any bonus for each output type.
This mod uses Content Patcher to change the Keg, Preserves Jar, Cheese Press, Mayonnaise Machine, Oil Maker, Dehydrator, and Loom so that item output quality matches the item input. Each individual input item category can be toggled on or off. Large milks and large eggs generate multiple cheese and mayo, and the amount is configurable. Golden eggs changed to copy the input quality and give a random amount of mayonnaise (3 to 10, configurable).
Reduce your cask time dramatically by producing wines and cheeses that are already at high qualities. Now there is a benefit to using deluxe fertilizer on your keg and preserves crops!

Fish Smoker already copies the quality of the input fish, so a mod is not needed for that machine.
Should be compatible with (won't break) most mods. Mods that add crops should benefit from this mod as long as they use standard fruit and vegetable tags.
Works great with Automate!
