    Sooo on 2019.4.0 LTS does that mean we can't enable raytracing (requires DirectX12) ?

    Do we just ignore the error being printed to the console constantly?

    It fixed my issues with Unity version 2019.3.12f1. I just remove the Direct3D12 and now I'm working with 11.

    Delete Direct X12 in Player Settings to fix this

    Has there been a fixed? Do you turn of DX12 and work with DX 11?

    We are locked into 2019 LTS and simply cannot upgrade to 2020 yet. Is this just a meaningless and annoying message we are going to see forever or does this error actually indicate that RayTracing simply won't work without DX12?

    The docs say that Raytracing is supported in DX11but the wizard sees it as an error if you don't use DX12 so not sure if I should trust Unity's documentation or Unity's configuration wizard (since they clearly don't agree) but we are starting out with Raytracing now and the first thing we see is "Error! Error! Error!" so... what do we do? :(
