I find out, that GT now has its own rock layers. So, is UBC obsolete now? I’ve just updated my modpack and want to make new start. I would like to have a better setup, both optimized and good looking.
Rock Layers & Underground Biomes Constructs
Its simple, get the Default Config Pack from the Download Page and then install Underground Biomes. That way GT6 will generate UB Rock Layers and UB wont lag the shit out of you.
