PROBLEM: Custom Helmet

Hi,

i have problem with helmet's custom 3d mode. I add it with 64x64 textures useing only mcreator options and it will be ok, but in game i see only 1 element of my helmet (core/base). I made helmet with horns and sth like tail and it isn't visable in game.

In code i have:

public static class ModelDragonHelmet extends ModelBase {
        // fields
        ModelRenderer baza;
        ModelRenderer ogon;
        ModelRenderer ogon2;
        ModelRenderer rog1;
        ModelRenderer rog2;
        ModelRenderer rog3;

and in game is visible only main part called "baza". If i change

armorModel.bipedHead = new ModelDragonHelmet().baza;

on

armorModel.bipedHead = new ModelDragonHelmet().ogon;

this second part is displayed correct...how to meka it displayed all parts of model?

I tried with: https://www.youtube.com/watch?v=8kMwGESqj28 but when i try to start client it gonna crush. Below full code, i tried many modifications based on this tutoril and i fail all the times. Pls help me...what i should change in code to make it work correct?
