Question BatchRendererGroup on mobile

Anyone know if there are particular settings/functions/etc to use so BatchRendererGroup work on Android?
I pretty much copy-pasted "BRGSetup" from Unity's own repository, and it work perfectly fine in Editor (or build for PC). However on actual mobiles nothing is displayed - outside of the regular meshrenderer'ed ground.

Tried with an OPPO A16s, a Samsung Galaxy S6, even with Bluestack and Nox just in case.
Scenes with regular MeshRenderer and DrawMeshInstanced both work fine, but not the BatchRendererGroup one.

It's Unity 2022.2.12, so it "should" be compatible - but it doesn't even raise an error.

 

Thanks, but "Keep All" was already on, since it wouldn't work when Built for PC otherwise.

The fix was to use the second overload of BatchRendererGroup.AddBatch; the one that take an additional offset and length.
Both must be set to 0 for regular platforms (when "BatchRendererGroup.BufferTarget" equal "RawBuffer"), and settings them to 0 & 16384 respectively made my scene work on all the aforementioned phones except the OPPO.
16384 was picked for being the lowest "SystemInfo.maxConstantBufferSize" among all tested phones (the Samsung).

I still have no idea what those values actually do (outside of the obvious "being an offset and size for some buffer somewhere"). I guess it's neither the GraphicsBuffer nor the Metadata array since they are already arguments, but Googling only return info about shaders that I'm not really sure are the same things.

At least it's working now, and working much faster than MeshRenderers&DrawMeshInstanced, so I guess the arcane of "why" it's working can wait.

 

In the Unity2022.3 version, BRG will have the problem of being unable to render on some devices. This problem will occur when I use the official Demo (brg-shooter) to package my own code. The device with the problem is Samsung Galaxy S5, which is a Old equipment, but it should support GLES3. I tested 2022.3.14f1 and 2022.3.18f1 respectively, and this problem will occur. When BatchRendererGroup.AddBatch is called, an error will be thrown: BatchRendererGroup.AddBatch windowSize parameter (16384) is over the limit allowed by the Graphics API (maxConstantBufferSize: 0)

 

Galaxy s5 uses Adreno 330, and despite GLES3 (which is also not always a metric, shader model should count too, but that’s a bit off topic) Unity disabled constant buffers support (which is required for BRG) for devices with Adreno 3xx.

Thanks for your enthusiastic answer, my problem was successfully solved. I can determine the device platform to bypass this problem.
