Feedback Wanted: Lightweight Render Pipeline

Also, switched back to OpenGL3 (no errors), but found a different issue not related to OpenGL2:

HDR on: everything looks fine, even if I change MSAA and Render Scale.
HDR off: Everything looks fine only if MSAA is disabled and Render Scale is 1. If I change MSAA or RenderScale, scene becomes really dark.

HDR disabled, MSAA disabled, Render Scale at 1: (Looks correct)


If I touch Render Scale (set it to .9)


Enabling HDR fixes issue:


Edit:

With HDR turned off, and MSAA disabled + Render Scale at 1, the game view looks correct but I just realized the scene view looks like rubbish now..!



I wish I could say there was something special about my project configuration but this is a fresh 19.1a12 project where I wanted to try out the LWRP. It looks like this right out of the box.

 

Your answer funny...
I need to download LWRP: [5.3.0] - 2018-11

 

Are you using Unity 2018? Then no, you can't, 5.x is for 2019.1 release, it's not backward compatible.

 

I got this error on cloud build when using Shader Lightweight Render Pipeline/Particles/Lit version 4.6.0 preview and Unity 2018.3

This is stack trace of error on cloud build.

That's not an LWRP change that's an editor change since 2017.2.

Option 1
Go to the model in your project view and select it
In the inspector for the imports settings and select Materials
There you will see a button that says "Extract Materials" select that

Option 2
Select the arrow next to the model in the project view
Select the materials underneath it
Right-click and Extract From Prefab

Guessing you haven't used a version since 2017.2 has been released until now
What you should know

Release notes

 

AO is not currently supported as post effect. The whole idea behind LWRP is that it's fast. AO has never been fast. They may change this in future, and allow people to make it slow again then they can also complain too!

 

Not within Post Processing Stack itself, but if you do a quick google, there are quite a few open source real-time AO solution for LWRP. There are also store asset like Amplify Occlusion now supports LWRP too.

But performance won't be great on less powerful hardware. One solution we checked took > 5ms on Intel GPU rendering to 720p.

 

I see, well you could look at using the progressive lightmapper. I think that would be a way of getting at AO data potentially - it has an API for that sort of thing. But most people will simply automatically generate AO textures as part of the art pipeline. Most artists don't think about AO any more. It's just there, provided by substance or other DCC package.

 

Just to be clear:

- Post Processing Stack is for real-time AO.
- If you want to bake per-scene AO into light map, you are talking about light mapper.
- If you want to bake AO maps per-object, you want to do it with another tool.



Now, if you can't seem to bake AO properly within Unity: adjust resolution, samples and AO settings. (And I don't need to tell you the light need to be "baked" and objects need to "static" etc.)

==== all above answers are not LWRP specific, if you have a LWRP specific issue, read below ====

If it still doesn't work and *only* doesn't work with LWRP Lit shader: setup on a simple scene, bake with Built-in pipeline then bake with LWRP pipeline using the same settings. Screenshot the difference, report it here and to bug tracker. It's the fastest way to get your issue resolved.

It would also be pretty helpful to know which version of Unity and LWRP you are on. As I haven't encounter AO baking issue myself.

Also note the light attenuation works differently in LWRP, not sure if it affects AO baking, but the result would look different, it's something you need to account for.

As for the lack of doc, I feel you, I have made a searchable unofficial site: https://bitinn.github.io/ScriptableRenderPipeline/LWRP/lit-shader/

 

To be clear I referred to the AO (occlusion texture) in LWRP lit shader, and mentioned the progressive lightmapper as a way of generating AO texture data since he seemed to be insistent about it being generated in Unity, and did not mention lightmapping.

 

The best help I can give at this point:

- Setup a test scene.
- Bake with built-in pipeline, screenshot
- Bake with LWRP, screenshot
- Screenshot the settings of your light mapper.
- Report everything here, show us the difference, along with your Unity version and LWRP version.
- Wait for LWRP team or more knowledgeable member for some advise.

Sadly I don't know a magic setting that will fix your issue as we don't have the full scope of you issue.

Hope this helps.

 

Please consider the possibility that you mess up something and don't even know it, and your reluctance to share more info are just going make this difficult for yourself

 

A quick scene to demonstrate AO baking works in LWRP:

 

Short answer:

LWRP isn't the issue, you need to understand AO baking in Unity.

Long answer:

Unfortunately, the Lightweight RP (Preview) template is precisely the worst baseline you can have, why?

- It use an outdated version of LWRP package.
- It depends on your version of Unity (which you still haven't disclosed).
- It obfuscates the things you want to learn: AO baking. Anything else is a distraction.

What you should do:

- Start from an empty scene to understand AO baking.

Here is my setup:

(Yes, there is no light in my scene, just ambient source.)



To add:

- Don't ask people to show you everything, you gotta try it yourself and show people what's not working so they can help.

- LWRP thread isn't the best place to get your answers, because your issue isn't LWRP related. It's Unity GI related. There is a forum for that.

 

Hi, thank you for your reply.
I tried to reproduce the GFX.WaitForPresent spike on a test project, but I couldn't. Maybe I need to instantiate more objects? I don't want to bother you by uploading the whole project...

For crash that occurs when using MSAA 2x on a Mac Mini 2014, it always happens on a fairly empty project. Unity 2018.3.0f2 + LWRP v4.6.0-preview. It does not occur on my iMac, so this issue might be hardware-specific one. Do you want me to submit a report?

 

Many thanks, I found out there is fix from Amplify after my post submission. I will try right away.

 

Hi Again!

I've managed to convert the Beffio shaders to LWRP 4.6.0 and Unity 2018.3.0f2. It seems to work but a new rendering artifact has come up (not visible in LWRP 3.0.0) as per this picture (look at the mesh pixelation around the mouth, 1st picture). It seems to come with the Culling Mask - Postprocessing with the MainLight_PB realtime light. Please see below. Any ideas if a bug or lighting setting? Many thanks

!

 

This is just a guess, but the likely issue is your object normal conversion is somehow wrong (or the object itself has non-smooth normal and somehow the original shader was overwriting it).

You might have better luck posting your graph screenshot to ASE thread (if you are using ASE).

 

Many thanks for your input. Here comes the ASE screenshot of the affected shader:

 

No they meant post in the ASE forums. This is not for ASE, ASE is not official, it is 3rd party and as such this is not really the place, even though it is sort of related to SRP.

 

Hello everyone!

So I've just updated my project to 2019.1 and the RP packages to 5.2.3. I know that multiple cameras is one of the features that needs to change with these updates, but I don't fully understand the process of what I need to add to support this (e.g. using a second camera / render pass for a simple skybox). Can anyone point me to a resource that explains which parts of the render pipeline need to be extended to allow for this? Thank you

 

^ This

Don't understand what used to be simple

 

A quick question:

What additional benefit do I gain from using UNITY_INSTANCING_BUFFER_START in the UnityInstancing.hlsl over the simpler CBUFFER_START?

Almost all LWRP shaders are written with CBUFFER_START instead of UNITY_INSTANCING_BUFFER_START, so is there virtually no difference?

(CBUFFER_START is defined per API so I am not sure when we should use UNITY_INSTANCING_BUFFER_START besides it was the naming for built-in pipeline)

EDIT: and for that matter, do we need UNITY_ACCESS_INSTANCED_PROP at all?

EDIT2: core's "UnityInstancing.hlsl" is included with LWRP's "Input.hlsl", but most of the API is not used by LWRP or Shader Graph, so color me a bit confused.

Thx

 

Im using this function in 'RenderPipeline.beginCameraRendering' to get a UI blur effect, it works fine on standard render pipeline, but failed on LWRP. More details here: (https://forum.unity.com/threads/lwrp-graphics-blit-failed.606166/).

Code (CSharp):

1. Graphics.Blit(rt, null as RenderTexture, blurMaterial, 0);

Any help?

 

Admittedly I haven't looked at your source code closely, but I think you are using multiple cameras, and expect to use result from one camera on another.

AFAIK, this doesn't work in LWRP, see:

https://forum.unity.com/threads/lwr...5-2-1-19-1-are-out.562291/page-5#post-4024615
https://forum.unity.com/threads/glitching-with-multiple-cameras-lwrp.592477/

But if you just want a blur scene as UI background, perhaps the LWRP's own Opaque Texture pass can help.



It will be different from Built-in pipeline's solution, but perhaps easier to implement once you know how to do it, see these examples:

https://github.com/UnityTechnologies/LWRPScriptableRenderPass_ExampleLibrary

 

Another quick question:

Why are both "IgnoreProjector" and "IgnoreProjectors" tag being used in different shaders in LWRP? Are they both valid? Projectors don't work in LWRP anyway, do they still serve the purpose?

(Unlit shader use IgnoreProjectors while SimpleLit and Lit shader use IgnoreProjector, so perhaps a typo?)

 

Thanks so much

 

Hi guys, It seems that LWRP doesnt support transparency properly.
After converting my glass materials of a door (albedo alpha -> transparency), to LWRP, its just only opaque, I tried all the options available, its either 100% opaque or completely invisible.
I exported the textures from Substance Painter, before 2018.3 without LWRP/HDRP it was working pretty well.
Any idea what is going on?
Thanks!
EDIT: I figured something out, even tho I dont know WHY it wants me to have it this way, doesnt make much sense of using the alpha channel for transparency control anymore, anyways, one small problem appears still...
This is a double glass, it has been placed on both sides of the door, it has a sticker wich is opaque, from one side the sticker is fine, and you can clearly and pretty well see that there is another one on the other side, so you see the backside of it, so far so good, but if you move to the other side of the door, this isnt the case anymore.
Normal door glass with transparency and stickers are opaque:


Looking good transparency and backface sticker is opaque and realistically rendered.


The other side same thing was expected, but the front sticker is getting render issues from the other side's sticker.

So basically from the other side, the front sticker overlaps with the backside one, creating weird rendering issues. Please note, this isnt a "doubleside" window, its a double window, with doubleside rendering. 2 Different meshes, same UV, same texture
I had to use Metallic alpha to get some transparency to show up, before any new Rendering Pipeline it was Source: Albedo Alpha. I kinda dont seem to get what's going on.

Thanks for any help!

Trying to bump this again with something a bit more specific..

So this chunk was taken from the LWRP.cs Render() function:

Code (CSharp):

1.             SortCameras(cameras);
2.             foreach (Camera camera in cameras)
3.             {
4.                 BeginCameraRendering(camera);
5.  
6.                 foreach (var beforeCamera in camera.GetComponents<IBeforeCameraRender>())
7.                     beforeCamera.ExecuteBeforeCameraRender(this, renderContext, camera);
8.  
9.                 RenderSingleCamera(this, renderContext, camera, camera.GetComponent<IRendererSetup>());
10.             }

I know you guys have said you're working on documentation but getting a look at something in-progress would be better than nothing at all right now. It's been kinda hard to hunt and peck around the files to figure it out for myself. Any kind of info about this array of cameras getting passed in, how it is supposed to be used, and if this is the correct spot to start extending it's behavior? Thanks again.

 

LightweightRenderingPipeline seems to be incompatible with Unity 2019.
In 2018 my project was working fine with LWRP, but nowI am just getting a pink screen and loads of errors such as:

Library/PackageCache/com.unity.render-pipelines.lightweight@5.2.3/Editor/ShaderGraph/LightWeightPBRSubShader.cs(5,19): error CS0234: The type or namespace name 'Graphing' does not exist in the namespace 'UnityEditor' (are you missing an assembly reference?)

 

Right click on the package folder and select reimport all and that should fix it. For me, it fixed some of my projects and other when I update to the latest 2019.1 Alpha a13. Not sure why but it's something to keep in mind if you are on an older version.

 

I'm sorry, but

isn't really enough for me to go on. How do I add a ScriptableRenderPass? How do i Inject the RP code?

 

The sample repo is a bit hidden but it is here:

https://github.com/UnityTechnologies/LWRPScriptableRenderPass_ExampleLibrary

(Continue to suggest my unofficial doc site until the next LWRP release with updated doc comes out)

https://bitinn.github.io/ScriptableRenderPipeline/

 

One more question (not holding my breath since my previous 2 Qs wasn't getting answers...):

UNITY_USE_NATIVE_HDR, this flag is only used once in the entire SRP project, but has no documentation. Is it referring to HDR flag on camera or the HDR flag on LWRP asset? Is it hardware dependent?

It's used to decide whether indirect specular should decode HDR environment to RGB. But the result is returned as such:

Code (CSharp):

1.  
2. #if !defined(_GLOSSYREFLECTIONS_OFF)
3. half mip = PerceptualRoughnessToMipmapLevel(perceptualRoughness);
4. half4 encodedIrradiance = SAMPLE_TEXTURECUBE_LOD(unity_SpecCube0, samplerunity_SpecCube0, reflectVector, mip);
5.  
6. #if !defined(UNITY_USE_NATIVE_HDR)
7. half3 irradiance = DecodeHDREnvironment(encodedIrradiance, unity_SpecCube0_HDR);
8. #else
9. half3 irradiance = encodedIrradiance.rbg;
10. #endif
11.  
12. return irradiance * occlusion;
13. #endif // GLOSSY_REFLECTIONS
14.  

In particular, I don't understand why encodedIrradiance.rbg is returned when the flag is set, does Unity store HDR environment image differently? As in storing Blue color in Green channel as Sky is more likely Blue or something?

 

Any news on premultiply yet? I hate talking like a broken record, but the blend mode's bugged, Acting more like an alpha blend.

 

I am seeing some strange behavior with Reflection Probe baking when using a metallic = 1, smoothness = 1 material.

I adjust environment light bounce between 2 and 5, and the black faces remain.



Is this a known issue for LWRP 4.6.0 + Unity 2018.3?

The more confusing thing is the face might bake just fine in some cases:



I will open a ticket later, not sure this is hardware dependent or not, but I am on macOS + Metal API + Intel GPU.

EDIT: This issue is now reproduced in 2018.3.1f and opened as case 1116857

 

Shadowmask lighting coming to LWRP?

 

Hi
Sorry for my ignorance but I am working with VR projects and I am interested in learning about LWRP, for it, Could anybody advice about course or tutorial about it?
Thanks in advance
Castana

 

Hi LWRP preview 4.7.0 has been released (2018.3.1.f1) but I don't see any notes in the changelog.
Could we have details before I update from 4.6.0 ?
