VK Error : VkResult is "ERROR_INITIALIZATION_FAILED"

I want to add texturing to my pipeline but when I run the script I get the following output to the command line:

Code: [Select]

BuildTexture: texture size = 4096, texture type = Diffuse map, source data = Images, blending mode = Mosaic, fill holes = 1, ghosting filter = 1, enable_gpu = 1, relaxed_precision = 1

The texture result seemed to be of lower quality, but if this error is normal I would like to know.

Hello bbbares,

The result quality shouldn't depend on this message, the GPU processing failed, but the fallback to CPU worked.

Which OS and which NVIDIA driver version you are using? Probably drivers for Tesla do not properly support Vulkan.

OS: Ubuntu 18.04.4

Nvidia Version: 440.59

I fixed this problem by installing the Vulkan SDK.  (there might be a simpler way by simply copying the ICD json, but this worked for me)

Instructions here: https://vulkan.lunarg.com/doc/sdk/1.2.135.0/linux/getting_started_ubuntu.html

As you'll see, for Ubuntu 18.04, just run these:


wget -qO - http://packages.lunarg.com/lunarg-signing-key-pub.asc | sudo apt-key add -
sudo wget -qO /etc/apt/sources.list.d/lunarg-vulkan-bionic.list http://packages.lunarg.com/vulkan/lunarg-vulkan-bionic.list
sudo apt update
sudo apt install vulkan-sdk
