Pyre's Embrace from Too many bows:

Default bow position:

/backslot transform render RIGHT_HAND

/backslot transform rotation x 90
/backslot transform rotation x 250
/backslot transform rotation x 90


/backslot transform rotation y 240
/backslot transform position x 0.2


/backslot transform to view the settings for an item. You can click on the yellow button to copy the settings to the clipboard in JSON format. Then you can use /backslot transform json to apply the copied settings to another item

Torchebearer from Too many bows:

/backslot transform json {"item":"too_many_bows:flame_bow","rotation":{"x":90.0,"y":240.0,"z":90.0},"translation":{"x":0.2,"y":0.35,"z":0.17},"scale":{"x":1.0,"y":1.0,"z":1.0},"mode":"third_person_right_hand","enabled":true}

Use /backslot save for save configuaration in config/flike/backslot.json
Use /backslot load for load configuaration from config/flike/backslot.json (It happens automatically on world loading

My mod:

Another backslot mod (u can't fix it):

The only problem I'm aware of is double rendering of item from another mod.
It happens when another mod is using its own render for this item.
  
Use /backslot transform render FALSE to turn off my render for this item.
Example: backpack's from INMIS

/backslot transform render FALSE
/backslot save
