Roads and rivers are working wonky for me, and emitting lots of compute shader errors:

Compute shader (CheckLocation): Can't find kernel (0) variant with keywords:

I'm using Unity 2021.3.7f1

Hey @woffles,

This issue typically only occurs when your machine doesn't support compute shaders. 
Is there a way you can send me your system informaton? 
 

Here's a guide on how to export it if you're unsure:

might've gotten me and the OP mixed up heh. @wilg is the person you're looking for, I assume.

I'm sure my computer supports compute shaders - it's basically brand new.

Plus, the same thing happens on my Mac, which has an Apple M1 Max.

Also, I believe something broke after install, because I also get compute shader errors now when painting terrain with a Gaia spawner, and in all sorts of other situations. That worked originally. I have reimported Gaia and GeNA multiple times.

Hey guys!

@wilg, Thank you so much for posting all the detailed information about the errors you're experiencing here. 
I've seen this error numerous times in the past and I only suggested looking if your computer supports compute shaders because it usually is in relation to that. 

However, I've also found that when those shaders fail to compile, it produces the exact same errors. This error basically means that the kernel inside that specific shader cannot be found, which typically means that it failed to compile. With that in mind, I have a few trouble-shooting things you can try and get back to me if they don't work so we can investigate further:

  1. Try completely deleting the GeNa folder and re-importing the asset from the asset store.
  2. Please select the file 'GeNaCarve' located in 'Procedural Worlds/GeNa/Resouces/Compute/Terrain Tools' and see if there are any outstanding errors in the Inspector window.

I didn't see any errors in any compute shaders in the project, either in the inspector or the console.

I tried deleting and re-importing both Gaia and Gena (and my Polygon Nature spawner pack). I'm not seeing the issue with roads now (though maybe it always worked?). I still see errors with both river splines and the polygon nature spawners.

Worth noting that Unity crashed while importing GeNa. I tried twice. It looked like it crashed after the assets were compiled and while GeNa was upgrading its spawners or whatnot.

I also got this message on import:

Also, now my scene view is flickering black rapidly if I try to make a river spline.

That message shows up in newer versions of GeNa because we originally made it originally supported by 2020.3 and Unity went ahead and moved the 'TerrainCallbacks' class to another namespace so internal DLL methods needed to be re-referenced. So unfortunately we can't remove this message because it would cause GeNa to not be backwards compatible.

Did you click 'Yes' on that message?
