Я пытаюсь создать закадровый проход, но ошибка добавляется перед закадровым, когда я создаю изображение глубины. Я взял функцию prepareOffscreen () от Sascha Willems https://github.com/SaschaWillems/Vulkan/blob/master/examples/offscreen/offscreen.cpp. Мне пришлось адаптировать его с C ++ на C и добавить поддержку многовидового просмотра. Аргумент ovrVkRenderPass используется только для получения совместимого формата цвета и глубины.
Я получил сообщение от слоев проверки:
Error: [Validation] Code 180358038 (...)
vkCreateImage: The combination of format, type, tiling, usage and flags supplied in the VkImageCreateInfo struct is reported by vkGetPhysicalDeviceImageFormatProperties() as unsupported.
Но я не могу найти свою ошибку.
