Question Is there a problem with shadow caster ?

Hello folks,
I have upgraded to Unity 2021.2.8f1 my project and now shadow caster works kinda weird.
The below images explain in more detail my problem.

Is doing some weird shadow...

While the only light and casting is working is one I have at the beginning of my level.

And sometimes doesn´t even cast a shadow on blue lights.
Upon oppening the project it asked me if I want to upgrade the materials and more stuff and I agree. Not sure if something else should be needed to have this working properly.

Any help will be appreciated.

 

Hello. I have the same problem. https://forum.unity.com/threads/2d-shadow-caster-with-multiple-lights-shadows-dont-work.1226892/ This guy has it too. https://forum.unity.com/threads/2d-...le-lights-shadows-dont-work-correctly.953285/
I hope they advise us. I don't have any ideas at all.

 

Thanks for the reply. I guess this is a bug ?
Anyways. I ended up for downgrading back to 2019 and shadow caster is working fine again.

 

I have the same problem. ShadowCaster seems buggy.

 

I have the same problem. I don't have a solution, but I now understand that if all the lights have something to cast a shadow with, it all works, if only one light isn't hitting an object with the shadowcaster2d component, the whole thing stops working.
Maybe this helps whoever is hopefully/maybe trying to fix this.
