Dear Cherno How are you, Cherno.

I am learning your course which teaches us building a ray tracer used Walnut as ui module. But when i run walnut,there are some trouble that I cant solve. when i push F5, it occurs that image image and the cmd shows “[vulkan] Error: VkResult = -6”，as we can see from the below image image

My English is poor,I'm sorry it may confused you.And i am looking forward to your help. I would also appriacite it if anyone else who will do me a favour. Yours， Armin

I could find this by searching on google: https://community.khronos.org/t/vk-error-layer-not-present-error/108749

Sascha Willems is saying this:

The code above only enables the validation layers, and if that fails it’s probably because you haven’t installed the validation layers e.g. by installing LunarG’s Vulkan SDK.

I don't know if this is your exact problem, but maybe try and look into it?!

Dear VagueLobster:

Thanks for your kindness and warm-heart.

long time ago(about 1 year) , I had installed vulkan SDK. After a system crush,I rebuild my windows system,So I think maybe at that time, the environment of Vulkan has been lost. Anyway ,I take your advice and reinstall vulkan the later version ,And it work.

I am very very gratitude to you for helping me. It means a lot for me a vulkan rookie who is in some trouble.Hope you have a nice day .

Yours sincerely, Armin
