Block rotations not working [1.19.2] [SOLVED]

[RInventor7]

Hi! I have a custom block. Now I wanted it to have rotations like standing sign block has. Added IntegerProperty for rotations and all rotations work perfectly fine except the block model. The rotation changes according to the placement (as it should be), but instead of the correct block model I see purple and black squared block. Created the block model with Blockbench, and I think my blockstate.json is also correct:

{
  "variants": {
    "rotation=0": {
      "model": "mymodid:block/my_block",
      "y": 0
    },
    "rotation=1": {
      "model": "mymodid:block/my_block",
      "y": 22.5
    },
    "rotation=2": {
      "model": "mymodid:block/my_block",
      "y": 45
    },
    "rotation=3": {
      "model": "mymodid:block/my_block",
      "y": 67.5
    },
    "rotation=4": {
      "model": "mymodid:block/my_block",
      "y": 90
    },
    "rotation=5": {
      "model": "mymodid:block/my_block",
      "y": 112.5
    },
    "rotation=6": {
      "model": "mymodid:block/my_block",
      "y": 135
    },
    "rotation=7": {
      "model": "mymodid:block/my_block",
      "y": 157.5
    },
    "rotation=8": {
      "model": "mymodid:block/my_block",
      "y": 180
    },
    "rotation=9": {
      "model": "mymodid:block/my_block",
      "y": 202.5
    },
    "rotation=10": {
      "model": "mymodid:block/my_block",
      "y": 225
    },
    "rotation=11": {
      "model": "mymodid:block/my_block",
      "y": 247.5
    },
    "rotation=12": {
      "model": "mymodid:block/my_block",
      "y": 270
    },
    "rotation=13": {
      "model": "mymodid:block/my_block",
      "y": 292.5
    },
    "rotation=14": {
      "model": "mymodid:block/my_block",
      "y": 315
    },
    "rotation=15": {
      "model": "mymodid:block/my_block",
      "y": 337.5
    }
  }
}

Why is it not working? What am I doing wrong this time? Thanks.

The blockstate.json doesn’t accept values such as 22.5 and 45.

After searching around for few hours and trying to understand how Minecraft sign block works, I came to conclusion that in order to rotate the block by 22.5 increments you would have to create a custom renderer.
