Black surface of the render

[Dellism]

I'm trying to make a render using data from 1.16.4 server using world-downloader. Render modes normal and cave works perfect, but smooth-lightning and lightning makes surface completery black excluding few blocks. I used this command: ./overviewer.exe "world folder" "render folder" --rendermodes=smooth-lighting.

I have the same issue with smooth_lighting and with smooth_night it doesn´t render any light sources.
It is a 1.15.2 Map downladed from a server with World Downloader
this is an other rendering that I made before(it wasn´t completly finished, the missing chunks are my fault)

with smooth_lighting

with smooth_night (very dark and without light sources)

same issue for me, a solution i found is to open the map in singleplayer, max out render distance and fly around, all chunks loaded will get thier lightning fixed on the render, but it can be very trippy to do on large maps, so would be good if we could get this bug fixed.
