Hey guys, does anyone here know of a good complete tutorial for creating a dimension in forge 1.9/1.9.4 or even 1.8? I have been searching for a couple of days now but I have only been able to find some from 1.7.10, which is a bit 'old'. Some things have changed method, while other things doesn't seem to exist anymore. And because it's this 'old' I find it rather difficult to find the new methods and stuff. It might just be me who are stupid, I don't really know, but any help would be nice
