Very curious, that option does not exist in the "IC2.ini" that i have.
The only mention of rubber trees i have is:
I am currently using "industrialcraft-2-2.8.16-ex112.jar"... which is the version Direwolf20 has in his latest release, "FTBPresentsDirewolf20112-1.10.0-1.12.2.zip"
I should be able to just add that code snippet you mention to the INI file "[worldgen]" section correct? (and regen world ofc.)
I am unable to locate any documentation or config options for stopping IC2 items (ie. Rubber Trees) from generating in specific dimensions (ie. The Betweenlands, The Twilight Forest, etc.)
Is there any documentation on this?
Does this setting exist?
