I don't know if you have a better place to post questions/issues, but the options menu in the world creation page isn't showing any options, any help would be appreciated 

can use this mod with mineralogy mod?

how can i config this mod i can't even start this

If you are getting "cascading worldgen lag" on your server when exploring new terrain caused by this mod, consider the following:

Turn down your coal spawn sizes, and possibly opt not to use the "vein" ore structures.

Explanation:

Normally, when you explore new undeveloped terrain, the server (or internal server on singleplayer) has to generate new terrain. It does this chunk-by-chunk as necessary, with a chunk being a 16 x 16 x 256 section of blocks. Vanilla Minecraft tries to avoid positioning any "structures" such that they overlap chunk borders. This is because if a chunk is loaded, and some structure inside can't be completed without loading another chunk next to it... well it loads that next chunk too. But maybe that next chunk /also/ has an incomplete structure, so it loads a third and fourth chunk, and...

Cascading worldgen lag.

The veins of ore, and in my case it was almost entirely caused by massive veins of coal, were sometimes hundreds of ores long. So to complete the generation of a vein of ore, the mod has to load several chunks. But then those chunks may also have a vein that causes more chunks to be loaded. With my settings, I found out that my server was sometimes stopping to generate 50 chunks because of ores when a vanilla server might have only generated a handful. 50 chunks is 3,276,800 blocks. While we were trying to play.

Turning down the size of our spawns (but increasing the frequency just a little to compensate) and setting coal specifically to use "vanilla" structures instead of veins fixed this issue. Now it's far less common for ore structures to cross chunk borders in problematic ways.

I didn't figure this out on my own, see: https://www.reddit.com/r/feedthebeast/comments/5x0twz/investigating_extreme_worldgen_lag/

and this mod: https://www.curseforge.com/minecraft/mc-mods/world-stripper

WorldStripper lets you eliminate a massive section of "filler" terrain and see just the ores and other interesting structures below the surface. That let me see that my coal veins were just absurdly massive, even if they didn't feel that way when I was playing on survival.

wiki is gone

In reply to lawremi:

 I'm pretty sure they mean the wiki linked in the top bar, which points to shoutwiki.com

1) Is there a better forum or Discord server for discussing and asking questions about COG?  I looked around and this is the best I've found.

2) I've been trying, and I can't seem to increase the density of the Railcraft poor ores in their sparse veins.  How do I do that?  The wiki isn't super detailed on dealing with the mod files.  I've tried to copy the RailCraft.xml to the custom folder, and then change the lines

<Setting name='OreDensity' avg=':= _default_ ' range=':= _default_ ' type='normal' scaleTo='base' />

 to

<Setting name='OreDensity' avg=':= _default_ * 4 ' range=':= _default_ ' type='normal' scaleTo='base' />

...but it won't parse that and breaks.  Suggestions?

I'm assuming you're familiar with your AppData folder for modding, but just in case you're not, I included the full path where this is located (on default settings).  Typically, (as in, almost always) mods are built to create .xml config files inside the config folder the first time you load a world.  If you don't see a config file you're expecting to see, start a world, and they should pop into existence.  After that, there'll be a CustomOreGen folder with the appropriate files that the COG wiki talks about.

Changing spawn frequently of coal ores or other makes redstone ore and gold ore spawn on surface but other than that work better than other these type of mods.

I'm hoping this is compatible with Ore Stone Variants, but by default, it seems like COG doesn't spawn any ores in any of the stone variants (diorite, etc). Even for ores in normal stone, HWLYA shows the block as being from their origin (Vanilla, Immersive Engineering, etc) rather than from OSV (which is what I would have expected, since it's what I see in other non-COG worlds). Is this something that needs to be tweaked in the config (and if so, what's the simplest way to do that?), or is it an issue with the order of events (ie, COG is destroying/overwriting OSV blocks)?

EDIT: I've got a custom config now with the veins replacing variant stone, but OSV still doesn't seem to be replacing them with its own integrated blocks. I guess they're both trying to do their thing "last" and COG is winning :/

In reply to lawremi:

 Aah, I see. So, within the same Veins element, is it possible to do something like:

<OreBlock block='ore_stone_variants:coal_ore:0' weight='1.0' />

<ReplacesOre block='stone' weight='1.0' />

<OreBlock block='ore_stone_variants:coal_ore:1' weight='1.0' />

<ReplacesOre block='stoneDiorite' weight='1.0' />

In order to match up the proper replacements, or is only one OreBlock element expected within the config?
