In Chinese, different Shapes are always referred to as Materials, so at first I thought you meant this.
I’m currently making these:Copper,Bronze,Invar,Steel,Wrougt Ingot.
I don’t know if I understand your steps correctly, but I think I did the same as you said.In order to avoid misunderstanding, I will describe my steps.
I found a recipe for making flour from flowers in config/recipes/shredder.cfg.Then change it to 0 as usual.Restart the game.There’s no flower in flour recipe.
Then I used MTUtils to add a recipe for using that flower to make something else.Restart the game. I can see this recipe in NEI.
But when the flower was put into Shredder, it still produced flour…
In addition, previous versions of Shredder showed more than 40,000 recipes in NEI, but now there are only less than 3,000.
It seems that only the recipes in shredder.cfg will be displayed in the click on the middle icon in the shredder.If that’s the case, I might not be able to turn off the recipes by changing them to 0.Because shredder.cfg doesn’t seem to have machine recipes.(I mean the recipes that turn machines into dusts.)
