    Just popping in to enquire if there are any plans to port DXR to Universal RP? I think this would be a very usable thing for me without the weight of HDRP on top.

    I thought perhaps Unity's DXR implementation wasn't tightly bound to HDRP in particular.

    https://docs.unity3d.com/2019.3/Doc...nce/Rendering.CommandBuffer.DispatchRays.html and other CommandBuffer.SetRayTracing* calls can be used from any rendering pipeline. It’s actually not mandatory to have a rendering pipeline or do any rendering to be able to do ray tracing work. Of course this will work as long as SystemInfo.supportsRayTracing is true. There are no plans currently to support ray tracing in URP but you are free to implement an effect if you need one.

    Thanks :) I think it's a shame that URP can't also reach high end but understandable.

    Why bump when @INedelcu already answered @hippocoder's question?

    As for your issue, what error do you get? From what I read here, 7.X is only compatible with
    2019.3
    .

    If you are looking for to do Raytrace Reflection effect in URP then you will get all the pain of HDRP weight :), (i.e to get correct quality you will need good sampling strategy, denoiser, temporal accumulation etc...). Raytracing without all this is very bad.

    2020.1 require 8.0.0 which will be out soon.
    7.2.0 don't work with it (due to some visual effect graph change)
