Bug SRP batcher does not work with OpenGLES3

URP 10.5.1
Unity:2020.3.14f1

 

Oh, I see, Thank you so much
I lose some important informations from you,hhh

 

Updated Unity and URP package then built for Oculus Quest. Some SRP batches show up in the frame debugger for Lit and other shaders, but Baked Lit and some others are not SRP batching. All the URP shaders SRP batch in the editor, but in builds the majority are still not being batched. Is there something I'm missing?

 

Well when I search the forums for "Quest SRP" guess what thread pops up first
If there is an answer to the question why does SRP run at an extremely low frame rate on the Quest then please point me to it. I have been unable to find ANY solution to this question

 

Hi team.
I'm just reading through this forum post trying to understand if this issue is the same as what I am observing in our project. I assume when you say that the SRP batcher doesn't work, basically it doesn't render anything and you're left with a blank screen, is that correct?

This sounds like it's exactly the same issue as we are having. I have another forum post explaining this, but the short version is that we're using Unity v2019.4.25f1, with OpenGLES3 on Android. We are using URP v7.3.1, and are unable to upgrade to anything above that version without it causing this blank screen rendering.

This has been a problem for a long time, but it has become urgent this week because for some reason whenever I load the project it insists on automatically updating to URP v7.6.0 without any input! When I manually download it back to v7.6.0, it doesn't work.

This is terrible timing because I'm less than a week away from our final build date, and I'm not able to make working builds.

 

That's probably unrelated to this thread, sorry. We are having issues with batching, no visible rendering issues other than low framerate.

 

Okay, at further investigation, this isn't related to my issue. Turning off the SRP Batcher has no effect, I'm still getting a blank screen rendering on URP 7.6.0+

Any assistance on my issue at https://forum.unity.com/threads/urp...es-black-screen-rendering-on-android.1099978/ would be helpful though

 

Hi, I upgraded from 2020.3.13 to 2020.3.14 and also updated the URP from 10.5 to 10.6 and get a load of errors.

Any suggestions ? Thank you.

 

Hi, i found that shader's SRP Batcher compatible state was different on GLES3 and Vulkan.

On Gles3,it says "UnityPerMaterial var is not declared in shader property section (xxxxxxx)".
On Vulkan,it compatible

2020.3.14+URP10.6

 

Just wanted to share that 2021.1.15f1 solved the issue for me. Thanks!

 

Still not working for us on 2021.1.15f1 using URP 11.0.0 and the default URP project scene.
Using OpenGL there's only "Draw Mesh" events and no "SRP Batch" event in the frame debugger.
If we switch to Vulkan the SRP batcher seems to work and the frame debugger only shows "SRP Batch" events.

 

+1

 

Any ETA for that version?

 

I am on 2020.3.14 and URP 10.6. These are the good versions correct ?

As you mention above, regarding OpenGL ES 3.1. that it should be compatible. Would it also work with OpenGL ES 3.0 devices, meaning the SRP batcher should be compatible with Android 4.3 (API level 18) as suggested by this website:

https://developer.android.com/guide/topics/graphics/opengl


My concern is to get the ETC2 compression compatibility as it is possible from OpenGL ES 3.0

 

I'm using unity 2020.3.15f1c1 + urp 10.6.0, the SRP Batching works well in Vulkan. But if the shader gets a little complicated, the batching will fail in OpenGL ES 3

---------------
Weird, after restarting the pc and rebuilding the app, it works out correctly now

 

@aleksandrk
Got a similar issue, though with a bit different error:
"A Hybrid Renderer V2 batch is using the shader "Universal Render Pipeline/Lit", but the shader is either not compatible with Hybrid Renderer V2, is missing the DOTS_INSTANCING_ON variant, or there is a problem with the DOTS_INSTANCING_ON variant."

2020.3.23 / URP 10.7.0 / Hybrid Renderer v2
Default URP shaders/materials. SRP Batcher is on.

Symptoms are pretty much the same as in this thread: works in Vulkan, fails with OpenGL 3.2 both in editor and on actual device. Though my issue is specific to entities and HybridRenderer v2. Maybe the fix you've pushed didn't make it into DOTS_INSTANCING_ON for OpenGL variant? Or it is by design and HRv2 is not intended to support OpenGL yet?

Case 1391439, just in case.

 

I encountered a similar issue on URP 12.1.7/Unity 2021.3.4f1 where after deploying our project to Quest 2 the SRP Batcher is mostly not working. I say "mostly" because RenderDoc shows that Unity's default URP Lit shader is getting SRP Batched but no other shader is (despite being labelled as SRP Batcher compatible and successfully batching in-editor according to the frame debugger).

Looking at the thread I see you mention SRP Batcher being only available on Open GLES 3.1 or higher, so I ticked off the box to require Open GLES 3.1 to no avail. Is there a way to get custom shaders to SRP Batch on Quest 2? And if there is, can you point me to the relevant documentation? Because searching on Google yields little more than this thread and other similar discussions. :/

 

I'm facing a similar problem with Unity 2021.3.5f1 using Omnishade, this shader inspector shows that this shader is compatible with SRP Batcher. Testing on editor the SRP Batcher works well, but when I build and test on Android device the SRP Batcher don't work. If I change the shader to Unity URP Lit the SRP Batch works on Android device too.

My Android device is a Xiaomi Redmi Note 8 Pro with Android 10.

 

I tested the same case on unity 2021.3.15f1 and the problem occurs. But on unity 2022.1.23f1 the SRP Batcher works with omnishade.

 

it's not working on 2021.3.5f1. use opengles32, bakedlit shader is not srp batch on mobile.
