How to add layer to first person hand?

[ozi]

I added a layer whis is changing the player's skin but the first person hand is still with the original skin. How do I change it as well? Thanks.

public class CustomLayer extends LayerRenderer<AbstractClientPlayerEntity, PlayerModel<AbstractClientPlayerEntity>>
{
    private static ResourceLocation skin;

    public CustomLayer(PlayerRenderer entityRendererIn)
    {
        super(entityRendererIn);
    }

    @Override
    public void render(MatrixStack matrixStackIn, IRenderTypeBuffer bufferIn, int packedLightIn, AbstractClientPlayerEntity entitylivingbaseIn, float limbSwing, float limbSwingAmount, float partialTicks, float ageInTicks, float netHeadYaw, float headPitch)
    {
        skin = Registry.location("textures/entity/custom.png");
        if (Main.isCustom())
        {
            renderCutoutModel(this.getEntityModel(), skin, matrixStackIn, bufferIn, packedLightIn, entitylivingbaseIn, 1, 1, 1);
        }
    }
}

You would need to handle some rendering logic via RenderHandEvent. The layers are only applied in third person as you can never see the player in first.

Oh thanks. I did my own rendering but the line mc.getTextureManager().bindTexture(Registry.location("textures/entity/custom.png")) doesn't seem to work.

Where and in what context? Also what is Registry#location?

I also tried copying FirstPersonRenderer class:

Probably because entity textures are bound using a batched rendering system and not on the fly. You need to handle the rendering of the model yourself, not delegate it to the PlayerRenderer.

You mean the player's model? Where do I do that?

Inside RenderHandEvent. You just need to do all the logic instead of parts of it.

Sorry for bothering you but I researched for hours and I still doesn't understand what is that logic.

[ChampionAsh5357]

Look at PlayerRenderer#render*Arm, copy the logic, change the texture being passed into the RenderType.

Ok I get it now but how do I get the player's model?

PlayerRenderer#getModel?

RenderHandEvent doesn't have a PlayerRenderer and mc.getRenderManager().getRenderer(mc.player) doesn't have the getModel.

[ChampionAsh5357]

It's probably called #getEntityModel then, that's the mcp mapping name.

I realized I had to use the previous rendering as well so it works now.
