Allows the use of the 1.21.11 model format in older versions with the help of black magic, specifically allowing all three axis (XYZ) rotation and incrementes larger/smaller than 22.5°, additionally removing the 3x3x3 size constraint.

Supports both rotation types:

All axis rotation

"rotation": { "x": 45, "y": 45, "z": 45, "origin": [ 8, 8, 8 ] }

Single axis rotation

"rotation": { "angle": 45, "axis": "y", "origin": [ 8, 8, 8 ] }

My models are not loading anymore

Try checking the model file for any extra brackets {} because Modern Model Format ensure a strict json validation.
