    When I set y camera to orthographic, there is a lot of noise added to the Ray Tracing Global Illumination.
    This amount of noise disappears instantly when the camera is set to perspective.

    There is already a denoiser that makes two passes on the noise.

    Isn't there something I can do about that?

    Hi,

    Unfortunately, ray tracing effects are not compatible with orthgraphic projection (not only RTGI). They will eventually be, but I do not have any timeframe to share right now.

    Best,

    Hello, thank you for this.

    I've noticed that noise appear in a wide range of cases when using HDRP so I gave up on the pipeline completely. It was doing more harm than good in my case. Maybe I'll convert back to it when it's more stable.

    In my case I have insane noise in 2019 LTS using normal Perspective camera
    Also, for some reason my terrain refuses to show. :(

    Before I added an override to enable Path Tracing to my global volume my meshes all vanished but the terrain was there. After I added Path Tracing to the global volume my geometry appeared, my terrain vanished and my entire scene looks like a TV with a serious need for an antenna adjustment :(

    Any assistance in getting rid of this noise and getting my terrain back would be most welcome!
