Official Unity Experimental HDRP DXR

athosrojas is not error...is updated HDRP Core . That I noticed when I open old RTX scene in new Unity. Just follow Wizard fix option.

 

its all ok with wizard, what i want to do more???

 

about my 360 render tests with dxr raytracing, decrease clamp values on global ilumination and increase range of denoise helped, but still unusable , the funy factor is on both windows( scene and game ) are totaly denoised now. but the render out is totaly noised. i will make more tests with monoscopic and with all supersampling options * TAA, FXAA etc

 

looks like denoise is turned off when recorder start rec frames. cause is totaly denoised and clean on both windows.

 

I really miss enlight realtime but i need a descent SSS shader, and the best one for legacy pipeline get distorcions when render 360

 

Edit
Nevermind, I posted some questions but I figured both out.

 

The raytracing works well in 2020 version. But In the 2021-1.04a , I have use the HDRP wizard to setup everything. And enable the raytracing feature in the HDRP asset. Add the global volume and enable the Screen Space Global illumination. But it's still not work.( Path tracing is ok)
Could someone give some advices? thank u

 

wenzy check HDRP default setting is there Ray-tracing ON. Also in new Unity they change a bit system GI.

 

better you got a print screen. cause, i do the same and still getting errors for raytracing dxr , like the guy sayed path tracing is ok but realtime dxr not all raytracing features give error msgs. its just dont working

 

It can be that he has Path Tracing but only with ray-tracing mode (no GI , only reflection/blur). But without screenshots is only guessing.

 

@Janusz_Biela , @wenzy (for alpha 1.0a4)

It seems as though the new alpha is buggy - I installed it and and found similar problems. At first, it won't allow you to turn on RTX settings, they are greyed out, then if you restart and mess with settings they eventually allow you turn it on after a restart - however the compilation errors don't clear and will not allow for Ray trace reflections or indirect diffuse.

I can pretty much re-create it every time on a new project (have tried 3 new clean projects, and converted an old one, all the same issue)

@wenzy - if you really want to work on on the alpha I would try the previous version or wait until the next one

 

i post the print screens with the errors you dont see?

 

its amazing how unity release totaly unusable releases. lol. they say " raytracing get improvements for 2x more fast" you go test and raytrace give you a console error like a bad made asset script from asset store.

 

athosrojas there must be issue with something. I use latest Alpha and it looks like is the best release of DXR !
Please post:
- yours hardware specification
- some screenshot errors
- screenshot of your DXR settings (volume)

 

Thank u for your reply. I have tried that but still not work. I can sure the volume settings are correct

The is the only issue on the Console.

Please fix all the compilation errors for Ray Tracing Shader "RaytracingIndirectDiffuse"!
UnityEngine.GUIUtilityrocessEvent (int,intptr,bool&)

 

i got the same for any DXR feature. ambient occlusion. ( like is on my print screen) for GI , for reflections, but i can run without raytrace, at this way i dont get any errors and get 2x speed up. ( with raytracing off )

 

I've the same issue here: Unity 2021.1.0a4, HDRP template converted to DXR

 

If this is some project you upgraded from older HDRP version do exit the editor, wipe the project's library folder to clear old cached shaders and start the project again. HDRP can often get random issues on shaders like reported here when you upgrade HDRP but don't clear the old cache manually.

 

Hmm that`s strange. I just open my Studio Scene in new Alpha 2021.0a4 and everything works smooth....

 

Other renders

 

Looks amazing @Janusz_Biela , very clean.
Mind sharing your post processing settings? (if you use any)

 

I have tried both ways.(Update from an old project or create a new project.) This issue is still exist. And the error message always come out when I enable the Screen Space Global Illumination om Volume.
Also I have tried to remove the HDRP10.1.0 from package manager and reinstall it but not work

Amazing!

 

I use my own post processing (off line CPU system) nothing fancy just my own Curve and color correction for shadows, mid shadows and bright area.

 

What am I missing here? Both those are enabled in the frame settings for the camera in my project settings, however the warnings dont go away:



Unity 2021.1.0a4 and HDRP 11.0.0

 

Probably those settings are not activated. Note that there will be more than one HDRP quality profile (for High, Medium and Low settings) and each one needed those checkerboxes enabled:

 

m0nsky ...here..like you see is very basic. But I use my own Curve and color balance because this what offers Unity is to much drifting for architecture renders. You can notice "old school system" color balancing with crossing shadows/highlights system.

 

To Unity coders: latest Alpha is really the best version of DXR so far.
Three big issues:
- in pure Path Tracing not working double side surfaces - other stuff: Perfect!
- still GI background in standard denoise system is broken (in pure PT works as should be)...I know this is difficult part of Global Illumination to deal with it....so still I must use Area Light outside interior to simulate background GI.
- There is limit distance visibility for Recursive Rendering (Preview). So if I want make background which is far from scene and Exclude it from GI it disappear (or I do not know how to setup it ):
- this is not issue: scene in reflection surfaces is much better than a few months ago...would be nice a little bit improve it (like poor quality GI or support AO)

 

It might be worth noting these are "alpha" releases - not even beta releases. You should expect bugs.....
Alpha releases are there to allow us to try new features early and report issues and bugs so they can be fixed for major releases

 

To the devs or anyone else.

Attached are the settings I am using for new projects - I have not had any issues with DXR until this release (alpha 04)

I have these errors if I create a new project or convert an old one



Update - still getting the same issue in Alpha 5

update 2- for anyone else having this issue, it might get solved by re-importing the RT (raytrace file) . Click on the error in the console to navigate to the file, right click and re-import.

I am not sure why it forces you to does this, but it seems to have fixed the issue - you will have to do this for each raytrace file (GI, reflection, renderer, subsurface, pathtracing and AO)

 

Any eta on when dx12 wont be slower than dx11? Id love to play with this for one of my projects (procedural world), however its also not worth cutting my fps from 70s to 30s even with ray tracing disabled which is what happened last time I checked a while ago (very new high end alienware laptop, so if that happens for my machine ... I can only imagine more normal specs).

 

Hi. Can we have some overview about the plans or roadmap
from

Screen Space Global Illumination
vs
Screen Space Global Illunination Ray Tracing (Preview)
vs
DDGI (RTXGI)

implementation.

The DDGI works best for me but it s not an official package.
Is it possible to get an preview package who works with 10.2.0 +

 

Has 10.2.0 been released with alpha 5? its not in my list to upgrade via the package manager (or can I only get it through git which I have been trying to avoid)

 

Thank u. Reimport the raytrace file is working ! But compare to my older version. The speed didn't run as what I expect . Actually . It has had the opposite effect , the framerate is slower than before . Wierd~

 

Does anybody know about HDRP 10.2/10.3/11.0 ray tracing support for new AMD videocards (RX 6800 and up)?

 

Unity uses something that's not in DX12 DXR spec? I'd assume things to just work.

 

Almost there! )

 

Dynamic D/N and the screen center cursor logic. Wow.

Do you use Raytraced Screen Space Global Illumination Performance Mode and Physically Based Sky Standard from Standard HDRP 10.2.0?

 

Both yes (but there are hotkeys for different ray tracing presets (up to GI qualtiy mode and path tracing) & script to auto-detect optimal preset on first run).

 

Hi everyone,

Does anyone know a solution to export renderered image sequences with Path Tracing? I was wondering if raytracing was production-ready but I did not find any way to export an image sequences for the moment.

Is Path Tracing the only way to enable raytracing in Unity? Path Tracing is not realtime and I thought games could do raytracing in realtime in Unity too. I don't get it from the doc.

Thank you!

 

Check the Small Office Raytracing Demo
https://github.com/Unity-Technologies/SmallOfficeRayTracing

There you can enable/disable these raytracing overrides.



and here an older overview which of these dxr raytracing techniques are used in actual games and demos...



You also could enable Unitys Path Tracing in an Volume override
https://docs.unity3d.com/Packages/c...ion@10.2/manual/Ray-Tracing-Path-Tracing.html

and use Unity Recorder
https://docs.unity3d.com/Packages/com.unity.recorder@2.0/manual/index.html
to export image sequences.

For better understanding of path tracing and bidirectional path tracing see
https://graphics.pixar.com/library/PathTracedMovies/paper.pdf

DXR Raytracing here
http://www.realtimerendering.com/raytracinggems/unofficial_RayTracingGems_v1.7.pdf

 

Its definitely not production ready as it is in alpha/beta.

If its the real time raytracing you are looking for (not pure path tracing), you can use the raytracing volumes as highlighted in keeponshadings link (raytraced GI, AO, reflection etc) . I recommend a gfx card of 2080ti and above to have a good experience in learning and authoring RTX though - Anything lower is frustrating.

Image sequences - Unity recorder can help with that (can be accessed via the package manager in the most recent alpha build (7))

 

I am sitting on the latest ALPHA (2021.1.0a7): THE BEST DXR VERSION since beginning ! You can use it without any worry.
...I see just right now appear 0a8 version....must check it.

 

Have you tried the latest HDRP from Git together with alpha 0a7, or you're just using the one that ships with 0a7?

 

newguy123 I use original one.

 

That's weird! When I enable Path Tracing I have to hold my mouse click to make the loading bar continue. I work on a RTX2060. A friend work on the same project with a 2080Ti and does not have this problem. The bar is loading by itself for him! Do you guys already meet this situation?

 

Are you in play mode?

 

Nope I'm working only in Editor mode. I just play the Timeline via the interface. When I enter PlayMode the loading is correctly done... I was just wondering if my situation had a fix since both my coworker and I need the same pipeline to work. Also we are just trying to port our project to raytracing and we are just so close to achieve it!

For people looking for a way to record with Path Tracing, this documentation looks very useful !

I noticed a comment by Remi here about the RTGI upscaling possibly getting removed. I just wanted to say that I make heavy use of upscaling (it's required imho), even modified my local branch to go up to 8x upscaling in low light because that's where the blue noise gets us in trouble more.

Here's a daylight example, I think it would be bad if we'd be forced to the 2x situation.

RTGI 2x upscaling


RTGI 4x upscaling
