Lot of noise with Orthographic camera and Ray Tracing

Unity Engine
1

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,

Hi, I have opened a case here that you can vote on Unity Issue Tracker - Orthographic camera projection is not working with Ray Tracing

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. :frowning:

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 :frowning:

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