Cave System lighting questions

[livid kayak]

Currently using URP:

So I have a very deep tunnel (mineshaft). I am using a directional light to light the surface of my scene, but the very bottom of the shaft is lit up. Is there a way I can make the bottom of the mineshaft completely dark if looking from the surface without completely removing the directional light from the scene (which in fact does solve the problem except it's now just night time all the time)?

Side note the underside of the cargo carrier you see in frame is lit up by two point lights.

It sounds like that's happening because the bottom of the pit is outside your shadow distance
If that's the case, you could use shadow cascades and stretch out the distance and last cascade to not lose shadow quality
Alternatively light layers, or baked lighting with distance shadowmask

Worked like a charm thank you!
