I made a chihuahua model as a rename for a dog. it shakes, this works with EMF and optifine without a modloader. When using optifabric, the chihuahua still renders, but it doesn't shake.

animation line:
[
{
"body_rotation.rx": 0,
"CHbody.rz": "if(anger_time > 0, 0.5sin(2.5time), 0.05sin(2time))",
"CHhead.rx": "if(is_sitting, head.rx + torad(25),head.rx)",
"CHhead.ry": "head.ry",
"CHhead.rz": "head.rz",
"CHleg1.rx": "if(is_sitting, torad(-45),leg1.rx)",
"CHleg2.rx": "if(is_sitting, torad(-45),leg2.rx)",
"CHleg3.rx": "if(is_sitting, torad(40),leg3.rx)",
"CHleg3.ty": "if(is_sitting, -1, -2)",
"CHleg4.rx": "if(is_sitting, torad(40),leg4.rx)",
"CHleg4.ty": "if(is_sitting, -1, -2)",
"CHtail.rx": "tail.rx + torad(45)",
"CHtail.ry": "tail.ry",
"CHtail.rz": "tail.rz",
"CHbody.tz": "if(is_sitting, -3, -7)",
"CHbody.ty": "if(is_sitting, 2, -2)"
}
]
