Me and some friends are trying to make a modpack and after a year away from the game, we all agree we want easy caving. We all played Attack of the B-team and loved the easy ore generation. After researching I found you can alter the COFH core ore generation. When i tried it never worked. I tried to use tutorials, but none really helped. When I edit the files the ore generation for vanilla the ores just doesn't change, but when I change the generation for a thermal foundation ore like copper it works. I also tried using the attack of the b-team files, but this also dint work. Any tips or tutorials would be great. Finally, were looking to make this 1.7.10 (1.8 if lucky) just to inform anyone who might help. Thanks
