Issues regarding World Renderer fog and world generation

I have a few issues currently, regarding the World Renderer fog and world generation:

1. I'm currently making a Mars dimension, using the World Renderer plugin to do the skybox. While basically everything works, there's an issue regarding sunset (sunlights). Specifically, the fog won't change colour to match the sunlights colour, and I don't know how to make it do that.
2. For whatever reason, anytime Mars's surface generation dips below sea level, the generation sort of breaks down and creates this pattern of hollow mounds, each about a chunk in width and depth. I have no idea why it does this, and I don't want it to be there.
3. Ore veins are generating on Mars. I'm not sure if this can be disabled, but if it can I would like to know how, and perhaps they can be implemented as an element or part of one for greater control.
