Can you explain why your pick is dark in all pictures, and there is no shadows, and everything is as bright as it can get??
It's legit that is why I called it cool finds. Emeralds can spawn next to each other as shown by my picture
Actually there is a mod that creates that same lighting effect, my friend uses it in dungeons when he runs out of torches. It basically reverses the light effect on everything, so light is dark and vica versa.
