Thanks, you gave me an idea.
@Override
public ItemCameraTransforms getItemCameraTransforms() {
ItemTransformVec3f firstperson = new ItemTransformVec3f(new Vector3f(0,45,0), new Vector3f(0, 0, 0), new Vector3f(0.40f, 0.40f, 0.40f));
ItemCameraTransforms itemCameraTransforms = new ItemCameraTransforms(firstperson, firstperson, firstperson, firstperson, firstperson, firstperson, firstperson, firstperson);
return itemCameraTransforms;
}
This works for the block! from the first person, the rest is easy to finish.
I am copied the transformation from a json file block.
