1 will it affect allready generated maps ?
2 if i use a flame thrower and set it on fire will the fire stop at some point or will it burn across the map ?
3 does the forest expand over time?

Hi there.

1. Sort of. If it's added to an existing save, new chunks will be affected, old ones will remain as is.
2. Be very, very careful with fire,
3. No, but there is another mod that does that.

Does it generate 2 kinds of trees? one that absorbs the Toxins and Increase Poison Trees, while the vanilla withers when too much toxic? or it just increase Density? How to use Influence Boost? Random Probability Penalty?

Hi,

This mod doesn't add any new trees itself - "Toxic" in the name really just refers to how oppressive so many trees can be, and it's a reference to a very old mod that first did something like this.

Basically the mod just makes tons and tons of trees, spawn.

Influence Boost and Random Probability Penalty affect the noise generation algorithms - each field has a tooltip, but I'd generally suggest leaving the settings as is unless you understand perlin noise.

But there is one exception: You can reduce Influence Boost if you want to experiment with dense forests that aren't quite 100% coverage.
