Describe the bug

At corners of blocks the floodfilled blocklight seems to get dropped straight to 0 like in this image.

This also happens with AO off.

I'm using embeddium 0.3.21 + iris 1.7.0 on MC 1.20.1.

To reproduce, just turn floodfill on with everything else being dafault.

I'd like to add that this effect also appears in the floodfill fog light propogation as well, making wall torch light look disconnected.

this is simply the lack of floodfill (ambient occlusion). its very strong right now. will most likely tweak it to be alot more subtle

Probably roll its behaviour back to before commit ccf5ebd?

it has been this way since floodfill was created.
