Omnifactory/Ores

Ores
In Omnifactory vanilla ores are generated less frequently, instead you have to rely on GregTech Community Edition mix veins. These veins come in four parts, with each part being a different ore and generate in ellipsoid shapes. The details as to how these ores generate are as follows: At the center of each 3x3 chunk section a specific vein type is chosen, if the ore can't generate in that dimension, the generator tries again. If the ore vein can spawn, the generator will choose a random height to generate at within the vein types min and max heights. Ore generation propagates from that point.

Note: See GregTech Community Edition/Ores for details as to what each column means.

Mix Vein Types
Different mix vein types generate in different dimensions. Listed below are the mix vein types for each.
