Здравствуйте! Решил я сделать кастомный инвентарь на 1.12.2 и добавить к нему броню , но у брони , точнее у рендера(просто накладываю текстуру на игрока как в ванилке) есть проблемки с отрисовкой на шифте да и в обычном положении , когда я смотрю в опередленном угле то у меня просвечивается армор , а у модели брони у головы смещается моделька когда я смотрю в разных положениях: посередке , вверх , вниз , скриншоты отправлю и если есть возможность фиксануть пробелы модели игрока в ногах и руках при ходьбе без PolygonOffset (потомучто из за большого значения появляются какито артефакты , а если поставить меньше то эффект пробелов останется) , то тоже буду рад , помогите пожалуйста.

Тебе надо в syncWithPlayerModel запихивать модель брони, зачем тебе синхронизировать модель игрока если ты рисуешь модель брони.

Java:

                BaseArmor armor = (BaseArmor) stack.getItem();
                if (armor.getArmorSlot().ordinal() != i) continue;

                Minecraft.getMinecraft().getTextureManager().bindTexture(
                        new ResourceLocation(armor.getTexturePath())
                );

                syncWithPlayerModel(playerModel, player, partialTicks); // хотя тут в целом достаточно эти 2 строки поменять местами
                ARMOR_MODEL.setModelAttributes(playerModel);

                ARMOR_MODEL.render(
                        player,
                        limbSwing,
                        limbSwingAmount,
                        ageInTicks,
                        headYaw,
                        headPitch,
                        0.0625F
                );

вот , это весь код который отвечает за отрисовку брони

Dmitriidev · 5 Окт 2025

я поменял местами 2 строки как ты и сказал

Artur114 · 5 Окт 2025

Тебе надо перед рендером делать ARMOR_MODEL.isSneak = player.isSneaking();

Dmitriidev · 5 Окт 2025

А , понял , теперь да , не просвечивает
