I wasn’t aware there was a raytracing support for Vulkan (DX12 only?) But this post proves otherwise:
Ray Tracing support using the Vulkan RHI (4-27 & 5-0) - #10 by focalcgi
The console command is different in vulkan, seems to be:
" r.Vulkan.RayTracing"
instead of “r.RayTracing.SomeRayFeatureHere”
If anyone knows of a library to manage raytracing and test for platform support, instead of dealing with the console, I’m interested
