How to fix this issue when trying to draw a texture on top of a model?

This page is a bit outdated. The use of VMA_MEMORY_USAGE_CPU_ONLY and VMA_MEMORY_USAGE_GPU_ONLY is deprecated. You should use VMA_MEMORY_USAGE_AUTO and set flags to a combination of one or more VmaAllocationCreateFlagBits.

Notice the following declaration code: bool load_image_from_file(VulkanEngine& engine, const char file, AllocatedImage& outImage); If references(VulkanEngine& engine) are used here instead of pointer，then this code doesn't seem to work. engine._mainDeletionQueue.push_function( [=] () { vmaDestroyImage(engine._allocator, newImage._image, newImage._allocation);}); When I click the close window button, vma gives an error:"Assertion failed: 0 && "Unfreed dedicated allocations found."I use pointer（VulkanEngine engine) instead of references，and then modify the function definition，code worked fine.

The Loading Images section doesn't cleanup the image view. It needs to add the following to the deletion queue. vkDestroyImageView(_device, lostEmpire.imageView.image_view, nullptr);

Is there a mention of texturedPipeLayout prior to the setup? I'm not really sure how to get past that, since it seems dependent on later steps.

I think this article is confusing image layouts with image tilings
