This means we were not able to correctly setup Vulkan. If you run the vulkaninfo program does it work correctly? Usually when this happens I check to make sure the various vulkan env variables (assuming your on Linux) are setup correctly. Namely, VK_ICD_FILENAMES and VK_LAYER_PATH need to be setup correctly.

Thank you for your answer. I have solved that my GPU do not support vulkan. I have try on another GPU, but VK_ICD_FILENAMES is error, it should at /usr/share/vulkan/icd.d/, I get this from https://vulkan.lunarg.com/doc/sdk/1.2.162.1/linux/getting_started.html[https://vulkan.lunarg.com/doc/sdk/1.2.162.1/linux/getting_started.html]

I believe the variable needs to point at the json file, not the directory that contains the file.

yes, it should point at the json file, but this file not at vulkansdk directory as readme

It would depend on where your driver put the file, so you'll need to go lookup how your driver sets things up. I don't know offhand where the file would be on your system. Sorry.

Can this bug be closed, it sounds like this isn't an Amber issue?
