Lightning issues with walls

I’m here to report a issue about lightning, most precisely the problems regarding corners. I’ve come to notice that whenever I create a room, the light manages to infiltrate trough the corners, even if there is no way for it to pass trough. My english is poor so I’ll leave an image for you to understand better:
This is the completely sealed room:


And this is the inside:

As you can see, the light infitrates trough the corners (somehow)
My graphics setting are at max, and I haven’t played around with the lightning settings, nor the part ones.
I’ve seen other developers struggling with this bug, and they fixed it by making the walls a lot thicker, or putting a enormous part in the sky that casted a shadow upon the room. I can’t manage to fit those in my game, so I tought that addressing the problem might have been a proper solution, given that it shouldn’t occur in the first place.

-The beta features I have active: UIDragDetectors, TextureGenerator, Live Animation Creator, Haptic Effects, Dragger QoL improvements, Assistant Mesh Generations, Acouistic Simulation.

That isn’t really a bug, thats just an issue with Roblox’s lighting grid being low res (every 3 or 4 studs iirc)

They are planning on increasing it so you’d just have to deal with that (or align the areas to the grid in a way to get around it) until that happens

not a bug. its just that roblox uses a 4x4x4 grid which decides whether to use the engines outdoor ambient or indoor ambient colours. ik its extremely annoying to work with, and indoor maps always need a giant ceiling above them to look even remotely good
