Christophe Riccio of LunarG has updated the Configuring Vulkan Layers white paper. Download this valuable reference as a white paper now!
Starting with Vulkan SDK version 1.4.335, LunarG has significantly improved configuring Vulkan layers by improving the workflow across environment variables, the layer settings file (vk_layer_settings.txt), and the Vulkan API VK_EXT_layer_settings methods to initialize Vulkan layers.
Vulkan Configurator can be used to quickly prototype and test a Vulkan layers configuration. Then these configurations can be exported to initialize the layer settings with all three methods:
- vk_layer_settings.sh and vk_layer_settings.bat: Terminal scripts (Bash for Linux/macOS, Command Prompt for Windows) that initializes layer settings using environment variables.
- vk_layer_settings.txt: a self-documenting plain-text file listing every available setting in the familiar <LayerName>.<setting_name> = <value> format.
- vulkan_layer_settings.hpp — a C++ helper header-only library that can be included directly in Vulkan application code to initialize layers programmatically via the VK_EXT_layer_settings extension.
These files can be used directly but can also be used as references to create user-defined files.
Each file is self-documented including:
- A brief description
- Links to specific feature documentation
- Dependence with others settings
- List to sub-settings
- Platforms supported
For developer convenience, the Vulkan SDK is shipping the pre-generated layer setting files initialized with the layer settings default values.
