Okay

I did the position of item, but there is only item(without hand). How to show the arm?

[Trahatron3000]

 @SubscribeEvent
    public static void armPose(RenderHandEvent event) {
        ItemStack stack = event.getItemStack();
        Hand hand = event.getHand();
        Item item = stack.getItem();
        MatrixStack matrix = event.getMatrixStack();





        if(item instanceof Lighter && hand == Hand.OFF_HAND)
        {

            
            matrix.rotate(Vector3f.XP.rotationDegrees(60F));
            matrix.rotate(Vector3f.YP.rotationDegrees(-45F ));
            matrix.rotate(Vector3f.ZP.rotationDegrees(15F ));
            matrix.rotate(Vector3f.XP.rotationDegrees(-40F));

            matrix.translate(0.2, 0.1, -0.3f);

            matrix.rotate(Vector3f.ZN.rotation(50));
            matrix.rotate(Vector3f.YN.rotation(51));
            matrix.rotate(Vector3f.YP.rotation(51));

            matrix.scale(1.4f,1.4f,1.4f);
        }
    }

I did it like this:

@SubscribeEvent
    public static void armPose(RenderHandEvent event) {
        ItemStack stack = event.getItemStack();
        IRenderTypeBuffer buffer = event.getBuffers();
        int light = event.getLight();
        Hand hand = event.getHand();
        Item item = stack.getItem();
        ClientPlayerEntity player = (ClientPlayerEntity) stack.getAttachedEntity();
        MatrixStack matrix = event.getMatrixStack();
        Minecraft mc = Minecraft.getInstance();
        EntityRendererManager renderManager = mc.getRenderManager();
        PlayerRenderer renderer = (PlayerRenderer) renderManager.getRenderer(player); // here is the error


        if(item instanceof Lighter && hand == Hand.OFF_HAND) 
        {
            renderer.renderLeftArm(matrix,buffer,light,player);
            HandSide handside = HandSide.LEFT;
            matrix.rotate(Vector3f.XP.rotationDegrees(60F));
            matrix.rotate(Vector3f.YP.rotationDegrees(-45F ));
            matrix.rotate(Vector3f.ZP.rotationDegrees(15F ));
            matrix.rotate(Vector3f.XP.rotationDegrees(-40F));

            matrix.translate(0.2, 0.1, -0.3f);

            matrix.rotate(Vector3f.ZN.rotation(50));
            matrix.rotate(Vector3f.YN.rotation(51));
            matrix.rotate(Vector3f.YP.rotation(51));

            matrix.scale(1.4f,1.4f,1.4f);
        }
    }

But it crashes...
