I have optifine and the weather mod for 1.12.2 and other mods too and for some reason when I create a storm or rain or anything, the clouds don’t get darker and stays white and even when the tornado spawns, the clouds is still white and idk what’s going on. Anyone know how to fix it?

I use Optifine 1.12.2 HD U F5, is this what you use?

This could also be a setting thing.
