Very odd lighting bug

[richm0nkey]

So odd words cant really accurately explain it. Screen shots and video below. The only lights I have is 1 enormous box light and 1 enourmous spot light (for shadows.) And the torches

EDIT:
The basic problem is when the player rotates their head the lighting makes weird triangular shapes and those shapes rotate and follow the player. best way i can describe it with words just watch the video you'll see

Another note about the third screenshot, I found when I looked at the ground the issue almost completely disappears. Only when i look down though.

The boxlight should max be 100x100 or it these bugs will come and haunt you.

Oh man it is set to 1000/1000 thanks

Oh man it is set to 1000/1000 thanks

No problem

No problem

So can he fix it by using multiple boxlights?

Yes if he put "boxlight_1" right beside "boxlight_2" it will still cover up really nice!

So does the max size of 100 apply to spotlights as well. because the error seems to come from the spotlight too. Fixing the boxlight made it A LOT better though . If this also applies to the spot lights is there a tutorial on how to light up night landscapes somewhere i'm not aware about? Removing the spotlight makes the terrain look kinda plain and reducing the size won't cover the terrain to make a more realistic moonlight lighting.

If a BoxLight is bigger than 500 it starts to make weird things, so just duplicate the BoxLight and put it right where the other should continue. Nothing complicated.

By what I know, SpotLights bug at 200 of Radius or 180 of FOV.

No, you shouldn't unless that area that have a different block box is blocked/unaccessible. The reason is because you can easily see a gap between the two.

Even if you put them at the perfect difference from each other?
