Salut! j'essaye de faire du rendu hors écran avec vulkan mais j'ai un message d'erreur que je ne comprend pas.

C'est lorsque j'essaye d'attacher l'imageview de ma texture ici :

void RenderTexture::createFramebuffers() {
            swapChainFramebuffers.resize(getSwapchainImages().size());

            for (size_t i = 0; i < getSwapchainImages().size(); i++) {
                VkImageView attachments[] = {
                    m_texture.getImageView()
                };

                VkFramebufferCreateInfo framebufferInfo{};
                framebufferInfo.sType = VK_STRUCTURE_TYPE_FRAMEBUFFER_CREATE_INFO;
                framebufferInfo.renderPass = renderPass;
                framebufferInfo.attachmentCount = 1;
                framebufferInfo.pAttachments = attachments;
                framebufferInfo.width = getSwapchainExtents().width;
                framebufferInfo.height = getSwapchainExtents().height;
                framebufferInfo.layers = 1;

                if (vkCreateFramebuffer(vkSettup.getDevice(), &framebufferInfo, nullptr, &swapChainFramebuffers[i]) != VK_SUCCESS) {
                    throw core::Erreur(0, "failed to create framebuffer!", 1);
                }
            }
        }

Et la création de la renderpass :

void RenderTexture::createRenderPass() {
            VkAttachmentDescription colorAttachment{};
            colorAttachment.format =    getSwapchainImageFormat();
            colorAttachment.samples = VK_SAMPLE_COUNT_1_BIT;
            colorAttachment.loadOp = VK_ATTACHMENT_LOAD_OP_CLEAR;
            colorAttachment.storeOp = VK_ATTACHMENT_STORE_OP_STORE;
            colorAttachment.stencilLoadOp = VK_ATTACHMENT_LOAD_OP_DONT_CARE;
            colorAttachment.stencilStoreOp = VK_ATTACHMENT_STORE_OP_DONT_CARE;
            colorAttachment.initialLayout = VK_IMAGE_LAYOUT_UNDEFINED;
            colorAttachment.finalLayout = VK_IMAGE_LAYOUT_PRESENT_SRC_KHR;

            VkAttachmentReference colorAttachmentRef{};
            colorAttachmentRef.attachment = 0;
            colorAttachmentRef.layout = VK_IMAGE_LAYOUT_COLOR_ATTACHMENT_OPTIMAL;

            VkSubpassDescription subpass{};
            subpass.pipelineBindPoint = VK_PIPELINE_BIND_POINT_GRAPHICS;
            subpass.colorAttachmentCount = 1;
            subpass.pColorAttachments = &colorAttachmentRef;

            VkRenderPassCreateInfo renderPassInfo{};
            renderPassInfo.sType = VK_STRUCTURE_TYPE_RENDER_PASS_CREATE_INFO;
            renderPassInfo.attachmentCount = 1;
            renderPassInfo.pAttachments = &colorAttachment;
            renderPassInfo.subpassCount = 1;
            renderPassInfo.pSubpasses = &subpass;
            VkSubpassDependency dependency{};
            dependency.srcSubpass = VK_SUBPASS_EXTERNAL;
            dependency.dstSubpass = 0;
            dependency.srcStageMask = VK_PIPELINE_STAGE_COLOR_ATTACHMENT_OUTPUT_BIT;
            dependency.srcAccessMask = 0;
            dependency.dstStageMask = VK_PIPELINE_STAGE_COLOR_ATTACHMENT_OUTPUT_BIT;
            dependency.dstAccessMask = VK_ACCESS_COLOR_ATTACHMENT_WRITE_BIT;
            renderPassInfo.dependencyCount = 1;
            renderPassInfo.pDependencies = &dependency;
            if (vkCreateRenderPass(vkSettup.getDevice(), &renderPassInfo, nullptr, &renderPass) != VK_SUCCESS) {
                throw core::Erreur(0, "failed to create render pass!", 1);
            }

        }

Merci.

EDIT fallait rajouté ça ici VK_IMAGE_USAGE_COLOR_ATTACHMENT_BIT  lors de la création de la texture :

imageInfo.usage = VK_IMAGE_USAGE_TRANSFER_DST_BIT | VK_IMAGE_USAGE_SAMPLED_BIT | VK_IMAGE_USAGE_COLOR_ATTACHMENT_BIT;

résolu!
