GI creating dark terrain tiles?

I created a procedural terrain script that allows chunks of terrain to spawn and generate as the player progresses through the terrain, I have noticed however since creating a script that generates a sky system (Sun, stars, moon, changing skybox colours) the terrain has dark and light areas.

in the dark, it looks like so


and from the inspector:

The issue is most of the “light” chunks are collider-inactive until the player gets to around 30m from the edge, where they are then activated to allow the player to step on to it

The white speckles, are just particles set at 5000radius in the center of the central chunk over a sphere emitter to simulate stars, so nothing to be alarmed about.

Any ideas?

I have same problem too! I am using only one big terrain, and i have like big square part of it darker.

i’m having this problem in 5.3.5 – did you figure out a solution?
