Description

The Khronos Vulkan Samples page VK_EXT_layer_settings - Configure validation layers programmatically explains the layer_settings sample in the official repository. It configures the Khronos validation layer from application code instead of environment variables or JSON settings files.

Coverage includes Best Practices and debugPrintfEXT, VkLayerSettingEXT chains before vkCreateInstance, and a UI toggling scenarios such as incorrect buffer usage and suboptimal image layouts. Validation messages stream into the sample UI with per-scenario warning counts.

Intermediate Vulkan C++ developers integrating validation into tools, CI, or teaching builds are the readers.

Docs on docs.vulkan.org link to sample source; run the debug build for UI-driven validation output.

Helpful when standardizing in-app validation toggles across teams without per-developer layer settings files.
