[1.15.2] [SOLVED] Custom Armor Model

[Obeeron]

Hello,
I have the .java models for all armor parts but I don't understand how to insert it within my mod considering I use deferred registries.
The different models have been made with Blockbench

I got the armor to render but it does not rotate with the arms/legs/head movement. It also does not change when sneaking or when sitting. However it does rotate all at once with when I turn.
Here are the 2 classes :
 

public class BronzeArmorModel extends BipedModel<LivingEntity> {
	public final ModelRenderer helmet;
	public final ModelRenderer chestplate;
	private final ModelRenderer bone2;

I was having the same problem and I believe it was fixed by changing the render method in the model class.

Here are my classes for reference

[Obeeron]

Mhm.. I replaced the functions in the model class as in your code but it now seems to render twice (at least for the head) and not in a.. let's say 'coherent' way

 

Here is what it used to look like:

Okay so I managed to make it match the head and legs rotation + sneak but as you can see the models are too high. The boots are at the start of the legs and the chestplate starts at the middle of the body

Here is the code :

Just to make sure, does it animate correctly?

If it does, then the way I fixed the problem you are having was by going in to tabula(what I used instead of blockbench) and opening up the player model. Then, make all of your parts childs of the player model. e.g. make helmet a child of the head. Once it is like that you should re align all of your parts so they are in the right place before removing them as children (even if it looks wrong) and deleting the player model from it and then exporting the model and doing the rest again.

[ChampionAsh5357]

I just answered the question about double rendering on the other post with custom armor models.

[Obeeron]

  Quote

Fun fact about global and local ModelRenderers: If you make a global ModelRenderer a child of some other model, it will render twice! So, for every ModelRenderer you add, you need to make them local variables within your constructor to prevent that. Also, you shouldn't need to copyModelAngles if they are a child of the parent ModelRenderer.

 

Expand  

Okay so if I understand correctly, this.bipedHead is the global ModelRenderer and helmet is the child, but you said I was suppose to make the local ModelRenderer local variables within the constructor. However I need to access them for the rendering part. What did I get wrong ?

[ChampionAsh5357]

You shouldn't need to call them from the render part. If they are attached to a child, they get added via super.render(); There should be no reason to access a child anywhere outside the constructor.

[Obeeron]

Okay so basically, if I get the render function like this :

@Override
	public void render(MatrixStack matrixStack, IVertexBuilder buffer, int packedLight, int packedOverlay, float red, float green, float blue, float alpha){
		helmet.render(matrixStack, buffer, packedLight, packedOverlay);
		chestplate.render(matrixStack, buffer, packedLight, packedOverlay);
		rightBoot.render(matrixStack, buffer, packedLight, packedOverlay);
		leftBoot.render(matrixStack, buffer, packedLight, packedOverlay);
	}

then it does render properly but the animations do not work.

And if I get the render function like this :

@Override
public void render(MatrixStack matrixStack, IVertexBuilder buffer, int packedLight, int packedOverlay, float red, float green, float blue, float alpha) {
	super.render(matrixStack, buffer, packedLight, packedOverlay, red, green, blue, alpha);
}

then the animations work but the the texture are totally mixed (see screenshot below)

In all the 'tutorials' I've seen, people enable / disable the models within getArmorModel function in the armor class like this:

model.helmet.showModel = armorSlot == EquipmentSlotType.HEAD;
model.chestplate.showModel = armorSlot == EquipmentSlotType.CHEST;
model.rightSleeve.showModel = armorSlot == EquipmentSlotType.CHEST;
model.leftSleeve.showModel = armorSlot == EquipmentSlotType.CHEST;
model.rightLegging.showModel = armorSlot == EquipmentSlotType.LEGS;
model.leftLegging.showModel = armorSlot == EquipmentSlotType.LEGS;
model.rightBoot.showModel = armorSlot == EquipmentSlotType.FEET;
model.leftBoot.showModel = armorSlot == EquipmentSlotType.FEET;

Should I not do it like that ?

[ChampionAsh5357]

Hmm. Well then here's a thing. With the current system you have, it doesn't really support the method of local ModelRenderers. There are two ways to do it. Either remove the addChild tags and correct the model locations yourself with what you had before my previous message or redo the entire thing.

 

I'm going to assume you're just gonna remove the addChild tags. From there you just need to fix the box locations which is easy enough to do.

[Obeeron]

Wait how do I fix the box locations manually

[ChampionAsh5357]

When you do ModelRenderer::addBox, it takes in a starting x, y, and z position. Just changes those to match where you want the model to be. Rotation should be handled by ModelRenderer::copyModelAngles.

[Obeeron]

To be honest moving them manually is way too hard, some of the pieces are tilted and it seems that they move according to their local rotation so.. I forfeit on that.
I'm willing to redo the entire thing because I prefer having something clean rather than twiking some values to cheat on the render.

Could you explain how to implement your local ModelRenderers method regarding 'setRotationAngles', 'render' and the constructor ?
If I get it right, I should only have the ModelRenderer variables declared within the constructor (otherwise they would magicaly be detected and rendered twice if I understood correctly) but then I have to change the .showModel boolean also in the constructor ?
Thank you!

[ChampionAsh5357]

If you want to do showModel, then you would call the parent (e.g. bipedHead, bipedBody whatever they are called) and then showModel.

 

If I'm not mistaken, this will show the default armor overlay as well. So the incorrect textures may have something to do with that afterwards.

[Obeeron]

Then what's the method to not use showModel

Expand  

I just said call the parent. So you would do bipedHead.showModel instead of helmet.showModel because the childs are rendered via the global renderer.

[Obeeron]

So here is what I get now (on an armorstand)

As you can see the textures seem heavily shifted.

 

 

Here is the corresponding code :

The armor in the top 64x32 will be rendered automatically since that is where the original overlay is. The only thing you should be rendering is anything not already in the 64x32 biped model space. I also just opened up your texture file. The mapping is going to be very wrong. A file size of 841x326 does not scale down to 64x32. It differs by a factor of .5 resulting in the half texture offset you see before you.

This isn't the texture, it's a screenshot of the texture oppened in Photoshop.
The original texture is 64*64 as I mentionned in the model constructor 

super(size, 0, 64, 64);

Here is the real texture :


So should I move the custom model texture outside the 64*32 ?

But it's the same issue as before? The top half of the texture is 64x25, 7 pixels short of the default 64x32. The default biped model renders the 64x32 area as its texture. Anything you add "must" be below that 64x32 area if you dont want it interfering in the default model. (I put must in quotations because there is some empty space throughout the model you could use).

Yup it's the same, it's because the one from my previous message was a screenshot for making it bigger on the screen.
Okay so correct me if I'm wrong, the top half 64*32 part of the texture is a default area used by the bipedModel. If I want to make an armorModel texture I should get into consideration some kind of template to avoid interfering with it (what template should I use ? an armor one ?). The parts of my armor that align with this basic template could have their texture on it. However the different armor parts that differ from a vanilla armor model should have their texture outside the 64*32 (or within the few empty space).

Also, why does the boots render correctly and below the player ._.

Yeah. The default armor model uses that 64x32 area. If you are constructing a texture that doesn't specific change the default model of the armor, then it would be applied just like any other armor texture.

I believe that has to do with the double child model and a case of lucky mistakes.

When declaring the width, height, or depth of your model, it adjusts the scale of the texture needed to be wrapped. In the example I took from you, a width and height of 5.0 and 4.0 are fine. However, .26 is not so much. Even though in the tabula it will look normal, Minecraft will actually take your image, scale it up, and reference it as if it was literally 0.26 instead of what tabula outputs. So in your case, to have a correctly mapped texture, it would need to be scaled up to 6400x3200 to correctly map those decimal values.

 

Also, a model with a size of 0.0 will not render anything. I believe it needs at least a 0.005 thickness to stop flickering.

This is an 'inflate' parameter, apparently it does not affect the texture.

I finally made it work thanks to your tutorial ^^ : https://championash5357.github.io/ChampionAsh5357/tutorial/minecraft/1.16.1/items/armor
