void vkCmdSetScissor( VkCommandBuffer uint32_t uint32_t const VkRect2D* commandBuffer, firstScissor, scissorCount, pScissors);

void FVulkanPendingGfxState::InternalUpdateDynamicStates(FVulkanCmdBuffer* Cmd)

This command sets the scissor rectangles for subsequent drawing commands when the graphics pipeline is created with VK_DYNAMIC_STATE_SCISSOR set in VkPipelineDynamicStateCreateInfo ::pDynamicStates. Otherwise, this state is specified by the VkPipelineViewportStateCreateInfo ::pScissors values used to create the currently active pipeline.

void vkCmdSetDepthBoundsTestEnable( VkCommandBuffer commandBuffer, VkBool32 depthBoundsTestEnable);

This command sets the depth bounds enable for subsequent drawing commands when the graphics pipeline is created with VK_DYNAMIC_STATE_DEPTH_BOUNDS_TEST_ENABLE set in VkPipelineDynamicStateCreateInfo::pDynamicStates. Otherwise, this state is specified by the VkPipelineDepthStencilStateCreateInfo::depthBoundsTestEnable value used to create the currently active pipeline.

void vkCmdSetDepthBounds( VkCommandBuffer float float commandBuffer, minDepthBounds, maxDepthBounds);

void FVulkanCommandListContext::RHISetDepthBounds(float MinDepth, float MaxDepth)

This command sets the depth bounds range for subsequent drawing commands when the graphics pipeline is created with VK_DYNAMIC_STATE_DEPTH_BOUNDS set in VkPipelineDynamicStateCreateInfo ::pDynamicStates. Otherwise, this state is specified by the VkPipelineDepthStencilStateCreateInfo ::minDepthBounds and VkPipelineDepthStencilStateCreateInfo::maxDepthBounds values used to create the currently active pipeline.

void vkCmdSetStencilTestEnable( VkCommandBuffer commandBuffer, VkBool32 stencilTestEnable);

This command sets the stencil test enable for subsequent drawing commands when the graphics pipeline is created with VK_DYNAMIC_STATE_STENCIL_TEST_ENABLE set in VkPipelineDynamicStateCreateInfo::pDynamicStates. Otherwise, this state is specified by the VkPipelineDepthStencilStateCreateInfo::stencilTestEnable value used to create the currently active pipeline.

void vkCmdSetStencilOp( VkCommandBuffer VkStencilFaceFlags VkStencilOp VkStencilOp VkStencilOp VkCompareOp commandBuffer, faceMask, failOp, passOp, depthFailOp, compareOp);

This command sets the stencil operation for subsequent drawing commands when the graphics pipeline is created with VK_DYNAMIC_STATE_STENCIL_OP set in VkPipelineDynamicStateCreateInfo ::pDynamicStates. Otherwise, this state is specified by the corresponding VkPipelineDepthStencilStateCreateInfo::failOp, passOp, depthFailOp, and compareOp values used to create the currently active pipeline, for both front and back faces.

typedef struct VkStencilOpState { VkStencilOp VkStencilOp VkStencilOp VkCompareOp uint32_t uint32_t uint32_t failOp; passOp; depthFailOp; compareOp; compareMask; writeMask; reference; } VkStencilOpState;

void vkCmdSetStencilCompareMask( VkCommandBuffer VkStencilFaceFlags uint32_t commandBuffer, faceMask, compareMask);

This command sets the stencil compare mask for subsequent drawing commands when the graphics pipeline is created with VK_DYNAMIC_STATE_STENCIL_COMPARE_MASK set in VkPipelineDynamicStateCreateInfo::pDynamicStates. Otherwise, this state is specified by the VkPipelineDepthStencilStateCreateInfo::compareMask value used to create the currently active pipeline, for both front and back faces.

typedef enum VkStencilFaceFlagBits { VK_STENCIL_FACE_FRONT_BIT = 0x00000001, VK_STENCIL_FACE_BACK_BIT = 0x00000002, VK_STENCIL_FACE_FRONT_AND_BACK = 0x00000003, VK_STENCIL_FRONT_AND_BACK = VK_STENCIL_FACE_FRONT_AND_BACK, } VkStencilFaceFlagBits;

void vkCmdSetStencilWriteMask( VkCommandBuffer VkStencilFaceFlags uint32_t commandBuffer, faceMask, writeMask);

This command sets the stencil write mask for subsequent drawing commands when the graphics pipeline is created with VK_DYNAMIC_STATE_STENCIL_WRITE_MASK set in VkPipelineDynamicStateCreateInfo::pDynamicStates. Otherwise, this state is specified by the VkPipelineDepthStencilStateCreateInfo::writeMask value used to create the currently active pipeline, for both front and back faces.

void vkCmdSetStencilReference( VkCommandBuffer VkStencilFaceFlags uint32_t commandBuffer, faceMask, reference);

void FVulkanPendingGfxState::InternalUpdateDynamicStates(FVulkanCmdBuffer* Cmd)

This command sets the stencil reference value for subsequent drawing commands when the graphics pipeline is created with VK_DYNAMIC_STATE_STENCIL_REFERENCE set in VkPipelineDynamicStateCreateInfo::pDynamicStates. Otherwise, this state is specified by the VkPipelineDepthStencilStateCreateInfo::reference value used to create the currently active pipeline, for both front and back faces.
