Description

This extension lifts some restrictions in the VK_KHR_dynamic_rendering extension to allow render pass instances and bound pipelines within those render pass instances to have an unused attachment specified in one but not the other. It also allows pipelines to use different formats in a render pass as long the attachment is NULL.

New Structures

• Extending VkPhysicalDeviceFeatures2, VkDeviceCreateInfo:
  • VkPhysicalDeviceDynamicRenderingUnusedAttachmentsFeaturesEXT

New Enum Constants

• VK_EXT_DYNAMIC_RENDERING_UNUSED_ATTACHMENTS_EXTENSION_NAME
• VK_EXT_DYNAMIC_RENDERING_UNUSED_ATTACHMENTS_SPEC_VERSION
• Extending VkStructureType:

Issues

None.
