Resolved How do I use the progressive path tracer ?

https://blogs.unity3d.com/2020/03/0...line-real-time-ray-tracing-is-now-in-preview/ This site says that progressive path tracing is available in the current preview, but I can't find it. I created a HDRP project and I searched through everything for like an hour but I could not find any way to enable it.

 

It's easy™
load in the HDRP package, press ctrl+space to bring up quicksearch and type "wizard", click on wizard and in the wizard click on the button that says DXR then the button at the top of this section should be something like "fix all", keep pounding it hard until all the checkboxes are green.
then in the volume, clik the + button, type "path" in the search and add all things pathtracer.
Then hope that you have an RTX or a 1080 ti, if you don't, learn to brew coffee like a cowboy (CC recommended)

you'll get more information on pathtracing here: https://forum.unity.com/threads/unity-experimental-hdrp-dxr.656092/page-15

 

Ah that did the trick. Also had to disable temporal AA, it caused camera jitter. Well, I think this needs some denoising but it looks acceptable with about 50-100 samples.

 

Another question, how do I disable the default scene illumination ? I tried all scene background lighting and fog settings, nothing makes a difference

 

HDRsky and Visual Environment I think.

 

I tried pathtracer and got some nice results (Rendertime 12minutes on RTX2080super):



I have two questions:

1. Is it possible to read the percentage of the samples the pathtracer currently reached at runtime?
(Should be easy since the Editor already has a progressbar.)
2. Is it possible to let the pathtracer render to a higher resolution than the current window/camera renders?
(Let´s say the gamewindow has 2K and I want to render to 4k.)

 

On Unity 2021.2.0f1 Pathtracer hangs after a second - anyone else?

EDIT: A TextmeshPro Object caused the Pathtracer to hang.
