Official Unity Experimental HDRP DXR

screenshot:

looks nice, was surprised about low performance though (with rtx 2080 ti) *i know its early test but still

 

Had to manually expand the template project file, getting this error when using Unity to create the project:

Unable to expand /Data/Resources/PackageManager/ProjectTemplates/com.unity.template.dxr-1.0.0-preview.tgz

Created issue https://github.com/Unity-Technologies/Unity-Experimental-DXR/issues/4

 

Is there a setting (or way) to enable multiple bounces for reflections. I am looking at more non-real-time art stuff so not too concerned with the performance. See screenshot of what I see in my game view-port currently. The small reflection of the sphere should show the gray floor. I was using the Unreal RTX earlier this week and they have this feature exposed and working. Just curious if this is possible now.

Spoiler: Screenshot

 

I don't have Nvidia, I have Intel HD but I have 8gb and Core i5, does that mean I can still experiment with this but it might run slow? Is this like the EEVEE mode of Blender? I can run that so why not this?

 

This version of unity won't run, even I upgraded windows 10 build version from 1805 to 1809.
How can I solve this? Thanks in advance

 

No. NVIDIA is the only company that currently supports Microsoft DXR. Having a good processor means nothing when you're trying to do raytracing. Saying it would "run slow" wouldn't do it justice. Performance would likely be measured as "seconds or minutes per frame" rather than "frames per second". We would have had it years ago if it were that easy.

No. EEVEE is not a raytracer. EEVEE is basically the same approach to rendering as a traditional game rendering pipeline like Unity's built-in and it's scriptable render pipeline.

 

RTX 2080Ti, and installed latest nvidia geforce display driver today

 

For me as well the Unity build won't even start. I'm just receiving a Windows error prompt like this


I'm on a Razer Blade Stealth Win10 v1809 i7-8550U, and will be connected with an external 2070. I don't have the eGPU with me right now and just wanted to take a peak.

Are you checking for Hardware Specs on launching the Editor already?

Unity-Experimental-DXR-0.0.1.zip downloaded, unzipped. When running Unity.exe then "This app cant run on.." when run as admin then "System cannot find ... \Unity.exe"
Please help.

Edit:
"You should clone the github repository. Make sure you have the large file extension installed too - https://git-lfs.github.com/before cloning it."
= I need to install git+ LFS= .zip file not working?

Trying add PATH variable. Not working.

 

When creating new project, I only have 2D and 3D options for template (no DXR). Any idea why?

 

O.K., you need to change install instructions then- change all "download" to "clone". Next, you need to tell us to turn on lfs BEFORE (?) clone (or not?). After standart GitHub Desktop installation, clone, running Unity.exe, new project I dont see DXR template.
Becouse com.unity.template.dxr-1.0.0-preview.tgz not unpacked!?

Edit: https://git-lfs.github.com/ installed BEFORE clone. Still no DXR template for new project...
Edit: unpacked com.unity.template.dxr-1.0.0-preview.tgz manually. No DXR template...
Edit: unpacked com.unity.template.dxr-1.0.0-preview.tgz manually, delete com.unity.template.dxr-1.0.0-preview.tgz . Got DXR template (be sure you are to create project for Unity 2019.2.0a5).
Edit by BFU:

Edit: delete local repositiry, restart, restart, restart, clone, no manipulation with com.unity.template.dxr-1.0.0-preview.tgz , got DXR template, new project.
Edit: No PC, Mac & Linux Standalone module loaded. Can not build.

 

Oh, that's why.
That Unity.exe of 134KB with no icon was actually pretty weird to look at - that was quite a lightweight version of Unity to be only 400MB

I was only curious to test it out. Any chance to get either a binary of the demo scene, or the direct download of the full package as it is right now? #instalazypeople

 

I've tried an alembic animated mesh and none of the different ray casting modes seems to work properly. The only ones that cast any shadows for that object seem to cast it from the meshes original position and then self-shadowing for example if the mesh moves below its original location in the animation. I assume this is just a current limitation with it being an alembic mesh. But hopefully it will work in the future.

Or am I overlooking an option that would fix this.

 

On a RTX 2080 Ti, latest drivers, I'm seeing really poor performance when looking at the lights and bottles (glass / refraction).

I've set the viewport to 1920 x 1080.

Up close < 5fps ,at a distance 15fps, then between 30 and 60 fps when light objects aren't in camera view.

What I am noting though, is that it's the same with the ray tracing options turned off, poor performance in vanilla HDRP when looking directly at the light objects with refraction.

I know this is experimental, but what sort of performance should we be expecting on top of the line consumer RTX hardware?

UPDATE: Just watching the stats window, I'm seeing the CPU main render times spike from 14ms with no lights in camera view up to 350ms when close to the light.

Seems to be a CPU bound issue rather than the RTX card. I'm running an i7-6700k @ 4GHz

 

Hi.
I tried the project but I get the following error.

Please fix all the compilation errors for Raytracing Shader "RaytracingAreaShadows"!
Please fix all the compilation errors for Raytracing Shader "RaytracingReflections"!

Also, I set the material's Render Pass to RayTracing, but it just appears black.
It seems that reflection is not normal on the scene.
Can i solve this?

Also, can I use Skinned Mesh Renderer ?

GPU is RTX2080.

 

Nvidia stated they'll be rolling out a driver update this April to bring DXR support to Pascal 10 series GTX cards. Will requiring an RTX card still remain true due to something specific about Unity's implementation here?

 

This should be part of the Standard Pipeline not just HDRP.

Also, the number of rays being used is way too much even on 2080Ti, don't expect stellar performance without reducing these.

 

-----------------------------------
I met the same problem.Did anyone solve it now?
I have created an issue https://github.com/Unity-Technologies/Unity-Experimental-DXR/issues/9

 

Unless plans have changed, I'm under the impression that the standard pipeline has no future when it comes to major new graphics rendering features.

Anyway, thanks to Unity for the experimental release, I have found it useful to play with at this early stage.

 

Will AMD's gpus get support for Unity's DXR?

 

DXR is directX raytracing, it's windows specific, it's not Nvidia specific. However AMD have said they won't include DXR hardware acceleration untill most games are using DXR. Meaning, yes it works, but it's slow af on AMD cards.

So... kinda? =/

 

They probably can't afford to lose money on a feature they probably have already internally, but didn't seem to be a marketing pull enough after nvidia announced it. Nvidia though can burn money as market leader.

 

The Neon Noir Demo could give us some Pascal, Volta, AMD Benchmark. But they do not.)

some find outs not without pain during clone and project setup....

besides

GIT LFS install
Windows kb4482887 update Windows 10 1809 for DXR support
Nvidia RTX Card

- use git lfs clone https://github.com/Unity-Technologies/Unity-Experimental-DXR.git
- git clone https://github.com/Unity-Technologies/Unity-Experimental-DXR.git did not work for me
- full checkout has 9,57 GB (10.285.807.584 Bytes)

- clone to shortest path e.g C:\

- connect Unity-Experimental-DXR/Unity.exe with Unity Hub
- create New Unit Project with DXR High-Definition RP (Preview) Template in Unity Hub
- choose project location with shortest path e.g. C:\DXR

shortest path actions because of
com.unity.template.dxr-1.0.0-preview.tgz
could not be fully extracted and manged because of very long filenames on Windows

e.g
Unity-Experimental-DXR\Data\Resources\PackageManager\ProjectTemplates\com.unity.template.dxr-1.0.0-preview\package\ProjectData~\Assets\3D MODEL\PROPS\Meeting_Room_Cradenza_01\New\Meeting_Room_Cradenza_01_Meeting_Room_Cradenza_01BaseColor.png

count is 241 charakters. windows max is 260 without hacking registry. only 19 left to run .)

 

At the point AMD support this will be when AMD cards are naturally fast enough with memory/ALU to not require dedicated hardware, and I think that does make sense but off topic. On topic, I hope Unity's new path tracer will not be GPU specific.

(and I would like decent realtime GI but that's another subject not for here).

 

sorry for going little off.
My hope is that the new drivers which add DXR support for Pascal GPU´s
allow working with Unity-Experimental-DXR for Non-RTX cars too.
At least working... not performing.)

 

Can anyone from Unity side talk to the CPU bound problems facing performance when looking at the glass lights and glass bottles.

Wondering if this is known issue, or something that will be addressed.

Is there a minimum spec on CPU for this sample scene? 3 - 5 fps isn't really workable (which is occuring when glass objects take up portion of screen. Significant drops when anything glass in frame, otherwise running 50+ fps.

Issues noted on a i7-6500k @4Ghz + RTX 2080 Ti.

 

The CPU issues are a known issue. This April 4th release is only for playing with the new features in development, a glimpse for people with latest GPUs who want to try while the API is under dev.

It's really fun but 100% not yet for production. See Seb's note from before:

 

Played serveral hours with this and i am totally amazed.
Where others show nice demos on youtube and o.5 fps generated movies, Paris delievers.

Looks great in pure HDRP and the additional integration of DXR effects is mind blowing.

The post processing stack did also a great progress. DOF feels finally production ready out of the box (please add some default autofocus on frame center, (yebis for unity has an great one));
and Bloom does finally what it should.

Next Level for Realtime Vis and Realtime Movie generation.
Must be fun to optimize this.

Hope there is some easy multi gpu scalability possible.

 

Thanks, did manage to miss that note above.

So I imagine the BMW sample was running on better CPU given all the glass on the car? New Razer blade laptops must pack a punch.

We're very excited for this tech as we work with a number of auto clients in the interactive space.

Looking forward to updates.

 

Same here, absolutely loving it so far. I bought an RTX card just for Unity and have been actively following all PR's ever since DXR support was announced. Would love to see some performance gains or some more supported light types(?)

 

Nice. I know this bike.) Are you working in the FIZ. Munich?

 

Predictive Analysis for Fontainebleau.
HDRP on. PP V3 on. DXR all in.
Sorry for that.)

 

I got these errors too, I am using a rtx2070.
Some .raytrace shaders can't compile at all due to they can't include BSDF.hlsl and ImageBasedLighting.hlsl from SRP core's ShaderLibrary folder


One of the console error, the BSDF.hlsl does exist, also the unity editor crashes every time right after creating the project or reimporting all the stuffs:

Shader error in 'RaytracingIndirectDiffuse.raytrace': Compilation failed [0x80004005 - Unknown error.] 'HLSLSource:14:10: fatal error: 'Packages/com.unity.render-pipelines.core/ShaderLibrary/BSDF.hlsl' file not found
#include "Packages/com.unity.render-pipelines.core/ShaderLibrary/BSDF.hlsl"

 

The car glass of the greenhouse you should fake. Performance loss is too big and needed for the rest of the car. Even with over 1000 Core CPU Realtime Path Raytracing you fake this. Render at last position on layer.

Modern Frontlights need Raytracing Depth around 15 and Backlights around 30 for photoreal vis.
So there still is a long way to do this in DXR.
It s worth it to create Light Fixtures and additionally bake light prisms.
https://blogs.unity3d.com/2019/02/05/create-high-quality-light-fixtures-in-unity/.

Think even with an DGX station thats the way to go for now. Performance is needed for the rest.

 

Is this motorcycle engine included in the project for free?

 

Wanted to check it out and also keep getting the "can't run this app" message. I cloned from git with lfs

 

Can anyone here (perhaps unity have some benchmarks internally?) comment on the max-q RTX cards in recent laptops being able to handle this demo well, or more generally how well they run unity?

Cheers
Jono

 

The BMW Demo build runs with 30 to 35fps on the GeForce-RTX-2080-Max-Q. 1920x1080 with all DXR effects on.
The non Max-Q Notebook should be at 35 to 40 fps.

After reading this i think there is some room for optimisation.
It is still an experimental pre alpha.
Lots of new thinking needed.

Yeah totally, I don't even own an RTX but the images coming from HDRP tracing are amazing. Please keep them coming so I can drool more!

I hereby give everyone 100% permission to spam your HDRP RTX images big or small

 

Please prefer DXR extended HDRP.) Hope Vulcan will come soon.
RTX speeds it up most for now.

first raytracing GPU. love. allows spectral raytracing without bvh.
