Transparent Material not casting shadows

Hello,
I recently upgraded a project from SRP to URP but now transparent objects no longer cast shadows (even when alpha is 1). There's also weird artifacts when objects are slightly transparent but I only see the odd artifact in Unity 2022 (Apple Silicon). Unity 2021 LTS (Apple Silicon) versions don't seem to have this issue.

When the material is opaque it behaves normally:


But when it's transparent it doesn't cast a shadow even when alpha is 1:


Here's the material's property's visible in the inspector:


Also here's the weird artifact I mentioned earlier which I believe to be a bug
it won't let me upload more files because I can't upload more than 5 (even though I only uploaded 3) so here's a link instead: https://share.cleanshot.com/hnJGKc. As you can see even when the alpha is 0 the object is still visible.

 

Hi,

Odd, I am wondering the same thing, so far can't find anything when googling or fiddling with settings...

Bye,

Jean

I posted what was working for me using the default shaders.
