Resolved 2022.1.0a16, 0b1, 0b2 URP WebGL is broken - FIXED in 0b3

As of 0a16, WebGL projects now crash on startup in the browser after displaying the official splash. Tested on Windows 10 with Chrome, Edge and Firefox. I've only tested with URP since that's what I use.

"[.WebGL-000009740D3D8E00] GL_INVALID_OPERATION: It is undefined behaviour to use a uniform buffer that is too small."


Edit: Firefox also displays this, which could be related: "WebGL warning: drawElementsInstanced: Buffer for uniform block is smaller than UNIFORM_BLOCK_DATA_SIZE."

Edit: Removed my link to a live build of the issue which I had included in this comment (as the issue has since been resolved). The attached image shows what was wrong and there's no longer any point to hosting a demo of it.

 

I am having the same WebGL issue when upgrading to 2022.1.0a16 using URP also.

 

Did this make it into the 2022.1.0b1? I am still having an issue, wondering if I needed to do anything else.

 

It's the same for me in 0b1 - though I didn't test the URP template this time. I've upgraded through pretty much every latest alpha and beta since 2019.something, so generally if my project doesn't work it's the same in the template.

For anyone stumbling on this thread looking to try 2022, the latest version where URP works with WebGL is 2022.1.0a15 - but most of the time you have to do a "Clean Build" or it will crash over a different issue. An alternative approach to get 0a15 builds working is to delete the Library/BuildCache and Library/Bee folders before each build.

 

2022.1.0b2

 

Rough ETA?

 

From 2022.1.0b3 Release Notes: "WebGL: Fixed errors rendering URP scenes with WebGL. (1385451)"

Confirmed - I have built and run my project in Chrome, Firefox and Edge! High fives all around, well done
