Ore System - Vein Structure

[Methes]

Each vein consists of Ores that are similar in origin. Main Ore type is accompanied by more rare ores in smaller amounts. Lists of these Ores are based on Gregtech 5 ore generation.

Each vein has different Density range spread over the whole vein.

• Highest densities are localised in the center - the Core of the vein
• Higher densities require larger veins
• Small veins might not reach their maximum Density

Density range is determined by Quality of the Vein.

• Quality can be poor, normal and rich
• Poor veins - Level 1 to 4
• Normal veins - Level 3 to 6
• Rich veins - Level 6 to 10

Veins differ in sizes.

• Small, Medium, Large, Huge
• The larger the vein is, the higher chance it has to reach high Density Levels
• Small sizes would be around 7x7x4
• Medium sizes around 15x15x10
• Large sizes around 25x25x15
• Huge sizes around 40x40x20
• Numbers are totally made up, tweaking highly recommended

Veins could be in different shapes. Concentrated shapes (without much stone inside the vein) are, however, preffered as the "stone mixture" is already expressed by Density.

These density gradients should be feasible via COG, at least for cloud-style distributions. In particular, see the "seed" attribute, which lets one place distributions at the same location. The lower the density, the larger the radius, with the highest density generating last to create a "matroska doll" pattern. I suggest that you start playing around by modifying the PFAA COG config. This is probably easiest by modifying the CustomOreGen_Config.xml to make it skip the mods sub-directory, and copy the PFAA config to the custom directory.
