armor size

so you mean like a custom armor design right?

then you have to find 2 items/files   Armor Name_layer_1

                                                     Armor Name_layer_2 

(Or something in the line of that. you can find these files somewhere in the .minecraft folder like get the iron or something and open it with some paint software (i use paint.net)

and you design it any way you like then to add it into Mcreator go to The "Tools" Tab and find "import Armor" and add the Armor Name_layer_1  and 2

P.S it has to have the _layer_1 And _layer_2   anything pass the _ Cant be cap or it wont be able to upoad it to mcreator intill you put that in the it of the fie

I think I understand what you are saying. You want to create an armor that acts more like a texture for the model and does not stick out as far from the base model of the character. If this is what you mean, then I have no idea how to do this without a lot of custom coding that I do not know how to do. I am sorry that I can not be of more help. I will use google to translate this into spanish for you.

Creo que entiendo lo que está diciendo. ¿Quieres crear una armadura que actúa más como una textura para el modelo y no se pegue a cabo tan lejos del modelo base del personaje. Si esto es lo que quieres decir, entonces no tengo ni idea de cómo hacer esto sin un montón de codificación personalizada que no sé cómo hacerlo. Siento que no puedo ser de más ayuda. Voy a utilizar google para traducir esto en español para ti.
