Bug Hybrid Renderer V2 and Shader Graph compatibility

Hello,

I am currently using the Hybrid Renderer V2 paired with a custom shader made in Shader Graph. I seem to be getting an error on Editor run and also building. Is there some sort of compatibility guide I should be following for Shader Graph and DOTS or is there a way to add a DOTS_INSTANCING_ON tag to the shader?

I am receiving this error:

A Hybrid Renderer V2 batch is using the shader "Shader Graphs/2D_voxel", 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.

I am using Unity 2021.1.2f1 but this error has persisted for multiple versions.

Thanks

 

Was also reported here with one Unity response so far: https://forum.unity.com/threads/hybrid-renderer-v2-0-4-0.847546/

 

Related bug reported by me and accepted by Unity:

https://fogbugz.unity3d.com/default...0.1428520959.1617836379-1129108679.1615920566

I also see that my 2021.1.0f1 shaders are also incompatible with 2020.3.3f1 LTS, which is particularly vexing. I am now afraid the shader file is trashed for good.

 

Also ran into this with Unity 2021.3.2f1. Sadly.

 

As posted also in another thread discussing this same issue: My fix to get my unlit URP Shadergraphs working again on 2020.3.3f1 (=last supported Unity version for DOTS for at least the rest of the year) was to downgrade Universal RP and ShaderGraph from 10.4.0 to 10.3.2. Which used to be easy via Package Manager; did it now via editing manifest.json:

Code (CSharp):

1. "com.unity.render-pipelines.universal": "10.3.2",

Snap..all error spamming gone, back to normal.

 

In another thread, @DK_A5B pointed out a fact that I have overseen.

Unity just announced that the Entities package (which the Hybrid Renderer is dependent on) is not supported on any version of Unity 2021

For me, I have trouble with HDRP, I'll try to downgrade and see if it's working otherwise I will downgrade unity back to 2020. Will see maybe also the lights will work in a combination with GPU Instancing, once I downgraded.

 

Wait what? Where did you read this?

 

here

Future releases of Entities will not be compatible with Unity 2021 until the end of the year at the earliest. Upgrading to 2021.1 and using current or future Entities packages will not work and is not expected to work.

 

One thing I should've added to my
A warning I want to add here. Downgrading (opening a project in a lower/previous version of Unity - e.g. opening a 2021.1.x project in 2020.3.x) isn't supported by Unity. This may lead to unexpected bugs and issues, so you'll definitely want to back up any projects before attempting it. A better approach may be to create a fresh project in the target version and then import/copy/recreate your assets from the original project in this fresh project. Obviously, depending on your project and what type of assets you have this can either be pretty trivial (just copying some source files) or rather time consuming (recreating nested Prefab assets).

 

Thanks! I'm daily in this forum, I can't believe I missed that. There are so many pins, I don't even see new pins. lol
