[1.15.2] Custom Armor Render problems

[Nozzomi]

I'm trying to render a custom helmet and the helmet rotates fine horizontally but it seems that it rotates on the x/z as well when I look vertically.

 

Here's a picture of what's happening:

Item class:

public class MythusArmorVar2 extends ArmorItem
{
    public MythusArmorVar2(IArmorMaterial mat, EquipmentSlotType slot)
    {
        super(mat, slot, new Properties().group(Mythus.MYTHUS_TAB));
    }

    @Nullable
    @Override
    public <A extends BipedModel<?>> A getArmorModel(LivingEntity ent, ItemStack stack, EquipmentSlotType slot, A _default) {
        if(!stack.isEmpty())
        {
            if(stack.getItem() instanceof ArmorItem)
            {
                KabutoHelmModel helm_model = new KabutoHelmModel(1);
                helm_model.bipedHead.showModel = slot == EquipmentSlotType.HEAD;

                helm_model.isChild = _default.isChild;
                helm_model.isSneak = _default.isSneak;
                helm_model.isSitting = _default.isSitting;
                helm_model.rightArmPose = _default.rightArmPose;
                helm_model.leftArmPose = _default.leftArmPose;

                return (A) helm_model;
            }
        }
        return null;
    }
}

Howdy

 

You might find this link useful - it is a working example of how model rotations work, including an 'interactive' tool for adjusting your model parameters by typing commands- makes it a lot easier to tweak the render translations and rotations.

https://github.com/TheGreyGhost/MinecraftByExample/tree/master/src/main/java/minecraftbyexample/mbe80_model_renderer

 

Off the cuff- the rotation point is probably not correct.  i.e. when your head tilts back, the y origin of rotation in your model doesn't correspond to the centre of rotation of the head.
