Storage Image operations and Transfer usage bits.

Are Load/Store/Atomic operations on “Storage Images” treated as Transfer Operations ?
Do these resources need to have VK_IMAGE_USAGE_TRANSFER_SRC/DST bit set or just VK_IMAGE_USAGE_STORAGE_BIT ?
Or in more general, are VK_IMAGE_USAGE_TRANSFER_SRC/DST required only on resources taking part in DMA/Blit operations (on TRANSFER/SPARSE Queue)?

If they had to use the TRANSFER_SRC/DST_BIT… there wouldn’t be a point in also having the STORAGE_BIT, would there?

Don’t over-think the specification. The spec says:

VK_IMAGE_USAGE_TRANSFER_SRC/DST_BIT indicates that the image can be used as the source/destination of a transfer
command.

Is writing to the image from a shader a “transfer command”? No. The spec says:

The set of transfer commands comprises vkCmdCopyBuffer, vkCmdCopyImage,vkCmdBlitImage, vkCmdCopyBufferToImage, vkCmdCopyImageToBuffer, vkCmdUpdateBuffer, vkCmdFillBuffer, vkCmdClearColorImage, vkCmdClearDepthStencilImage, vkCmdResolveImage, and vkCmdCopyQueryPoolResults.

None of those perform rendering operations.

That makes sense.

Image Store/Atomic operations are not rendering operations, they are render pipeline side effect operations similar to Transform Feedback/Stream Out.
Usage bits looked different before final release, thus my question.
