Dark god ray effect

[Ghost60606]

So I've had this bug for a while. I used to tolerate it, but it's getting annoying.

I have these weird shafts of dark light. Like god rays, only dark and shadowy. They only seem to kick into effect on overcast or gloomy/rainy days. In a forest, they can make it almost too dark to navigate.

See image attached...

I've made a few changes to the ini's over the months and years, but can't remember exactly what.

I use ELFX shadows and it's various patches and add-ons. - Disabling these didn't remove the effect.

I use Obsidian ENB. - Disabling this doesn't remove the effect.

I have particle patch for ENB - esp disable as guided by loot.

I have obsidian weathers - which as far as I know shouldn't cause this sort of anomaly.

Anyone else had this effect in their game? I'd really appreciate some help with this. Thanks.
