[1.12.2] Item Transforms Misbehaving

[sci4me]

I am creating an item that uses an OBJ model. I have a corresponding JSON blockstate using the Forge format, where I set my transforms. I have used the Item Transform Helper mod to figure out what these transforms need to be. However, whenever I print those transforms with the helper mod, copy them into my JSON file, and load the game, my translations end up wrong! It's like they're being multiplied or something, it's really weird... For example, my item displays much further above where it should in GUIs. Whenever I check what the transform values are using the Item Transform Helper, they aren't what I specified in my JSON file! The rotations and scales appear to be unmolested but the translations aren't.

What's going on here?

 

Update: setting the translations to 0 gets the item relatively close. It looks like the translation values created by Item Transform Helper are 120% drunk. And the error doesn't _appear_ to be related to the scale settings either...
