Я делаю простой рендерер (временно) на вулканском языке, и на данный момент я делаю это действительно просто. Я получаю исключение в vkCreateGraphicsPipelines (), в чем может быть проблема и как я могу ее исправить.
Я пытался найти что-нибудь, что не было инициализировано, но пока ничего нет. Я проверил стек вызовов, но ничего не получил, так как исключение выдается при вызове функции create для конвейера. Я также искал в Google, но не нашел ничего, что помогло. Я слежу за сайтом с учебником по вулканскому языку, просто абстрагирую его от разных классов, проверил учебник несколько раз. Все работает, пока я не доберусь до функции vkCreateGraphicsPipelines.
