Carla: Vulkan driver error

[Abanoub-G]

Hi,
I am having issues with the latest Carla version. When I run make launch I get "Cannot find a compatible Vulkan dirver".

I have tried installing Vulkan from http://linuxconfig.org/install-and-test-vulkan-on-linux but still getting the same error.

Has anyone got an idea why this happening...?

Thanks in advance :)

Does your hardware meet the minimum specs? The Unreal build instructions mention them I think. What OS and what GPU? You can probably switch to the opengl backend somehow, though I don't know how for the editor.

yeah I think the specs are absolute fine, I have been using CARLA for a while on this same machine but it's just when I upgraded carla to the latest version I ran into this. Yes I was also trying to see how to make it use opengl in editor mode but I couldn't find it either...

Any idea how I can make carla use opengl in editor mode?

Hi Everyone,
I have solved this now. In case anyone is running in the same problem, the solution is:

• Go to ~/carla/Util/BuildTools/BuildCarlaUE4.sh
• Open it and change RHI="-vulkan" to RHI="-opengl"

That should make the "make launch" default settings set to use opengl instead of vulkan.

Hi,

This works if building Carla from the repo. Is there a way to use opengl with the deb version?

Thanks in advance!
