Vulkan loader not searching correct paths for layer files?

396 views Asked by At

I'm having a problem where the vulkan loader appears to be ignoring some of the environment variables I have set. VK_LOADER_DEBUG=all works but VK_LAYER_PATH and VK_ADD_LAYER_PATH both seem to be ignored. Can anyone identify the reason for this?

% env | grep VK
VK_ADD_LAYER_PATH=/Users/david/VulkanSDK/1.3.236.0/macOS/share/vulkan/explicit_layer.d
VK_ICD_FILENAMES=/Users/david/VulkanSDK/1.3.236.0/macOS/share/vulkan/icd.d/MoltenVK_icd.json
VK_DRIVER_FILES=/Users/david/VulkanSDK/1.3.236.0/macOS/share/vulkan/icd.d/MoltenVK_icd.json
VK_LOADER_DEBUG=all
VK_LAYER_PATH=/Users/david/VulkanSDK/1.3.236.0/macOS/share/vulkan/explicit_layer.d

Appears the issue was causes by linking MoltenVK before vulkan, switching them around fixed this issue.
