Question

Hey guys, I run into a very weird thing regarding lighting.

My walls are not stopping the light at the other side.

After the shaders it´s really noticeable

Any idea where should I start looking? I am happy to provide any info you may need.

Enable shadow casting for the light source(s).

I am an idiot, I have done this for every other light source that needed it and somehow forgot to do it for this one.
Thank you very much for your answer.
