The list of all Mizuno’s items can be seen on their blog here: https://mizunomcmemo.blogspot.com/p/cit.htmlSince i use it a lot (and my minecraft likes to crash if i have chrome open at the same time), I put it into an easier-to-read image for myself that i’ll share here:
To actually -USE- the items, you’ll first have to decide which one you want. For this example, i’ll use the apple on a cutting board (which is the 4th apple item at the top of the list!). The item is named “Apple_3″. So take a regular apple in Minecraft (not a golden or enchanted) and place it in an anvil. Name the item “Apple_3″. If you did it correctly, the apple will change model in the right side of the anvil! (Make sure you don’t put any spaces after the last letter of the word). Take the item out of the anvil, and place it into an item frame, and you’ll see the 3d model! (Some item frames need to be placed flat on top of a block, on a ceiling, or on a wall to work correctly. Don’t forget, you can right-click the item frame to rotate it too!) Other items that have longer names (Say, “Beetroot Seeds” will have a space in their name. So to make them into an item it’d be “Beetroot Seeds_0″ the underscore and number always come AFTER the last letter. No spaces!) If you still have questions, let me know and i’ll see if i can make a video to explain it better <3 I hope this helps!
