How to prevent spot light from shining through/under walls?

I have found many topic with this questions, some from 2013, but none of them seem to give the answer to this.

I have a spotlight that is directed towards a corner of a wall. But whatever I do, the light can't stop shining through the wall and be visible on the other side:



The properties of the spotlight:



This is even more problematic in my case considering I need very strong intensity light with high range and spot angles.
I've tried "merging" the wall and the floor into a single mesh exported from Blender but the problem is exactly the same.
Is that a known problem that developers are used to cope with? I'm using URP.

Thanks!

 

It looks like this problem can be avoided if the light is facing the wall + the near plane value is correctly set up but as soon as the light turns a little bit you can see it bleeding through the wall again.

Still no one to help me with this?

 

Hi Kromah,
I have the exact same question on the topic. It is frustrating to understand the reason for this.

Are you experiencing something like i asked about in this post (watch the video)?

This seems to be a similar issue and solution: https://docs.unity3d.com/Manual/ProgressiveLightmapper-UVOverlap.html

 

Hi @corb555. Thank you for the comment, however that is for objects using baked lightmaps. Are you using realtime light @Kromah? In the example I linked to I am using realtime lights. No better luck if I join the geometry.
