The scaner is meant to get exact values.
The first effect is called smog. I did not yet get that working. It is meant to be a visible filter, like when in thaumcraft there is some eldritch stuff going on. Air becomming brown and muddy. This i meant to start early before any real effects come out.
So far i tried to do the effect for a few hours so far, but i will try it later once again. Coding stuff about visuals is certainly not my strengh.
