Hi,

as the description says, having a 3d image view of a 3d image and using this view as render target does not trigger any errors.

Tested with 1.1.69.0.rc.334

I'm having a hard time finding spec language that explicitly forbids this. VkImageType is not mentioned in either VkAttachmentDescription or VkRenderPassCreateInfo(2), AFAICT. It's probably not what the user intended, arguably. It might just end up with a frame rendered into slice 0 of the 3D image?

It's not unlikely I've just missed the statement or inference chain that prohibits this - if so please point to it and re-open the issue. Otherwise I'll add this as a warning for the assistant layer, #24.
