To enable Vulkan validation layers for Quest builds, activate the VK_LAYER_KHRONOS_validation layer in the erhe graphics configuration file and wipe the SPIR-V cache to recompile shaders with validation enabled.

Silent rendering failures in erhe Quest builds often indicate undetected GPU hangs. Enabling Vulkan validation layers helps diagnose the issue by reporting hidden errors during the rendering pipeline.

Yes, the Vulkan SDK is required to enable validation layers in erhe Quest builds. You must modify the erhe graphics configuration file to activate the VK_LAYER_KHRONOS_validation layer at runtime.

To disable Vulkan validation layers for performance optimization, remove or turn off the VK_LAYER_KHRONOS_validation setting in the erhe graphics configuration file before relaunching the Quest application.

You can confirm the Vulkan validation layer is loaded by monitoring the application logs for validation messages after enabling it in the erhe graphics configuration and wiping the SPIR-V cache.

Use Vulkan validation layers for GPU debugging when a Quest build hangs at the Horizon launch panel, renders nothing in VR, or misbehaves silently, to detect and report underlying rendering failures.
