please fix adjoining landscape problem

Yup I am, WC is annoying, making lighting ‘realism’ a sad waste of time, but many are saying similar things,I may be missing something not sure, but lighting a 5101x5101 terrain, and thats just ONE of my 4 WC tiled world, is a endless job filled with stress.

ONe area of that terrain looks nice, yet other areas on same terrain look FLAT and DULL because the light isn’t shinning right there, and I do have EXP fog there,so its a nightmare getting GOOD lighting when you’re rig is insufficient for raytracing &/or you aren;t able at MINimum to be using a RTX 2060,getting there but no.
