Retrogen is a hit/miss thing. Also, I believe it helps to unload and reload chunks... So walk out about 200 blocks and return
No it's not, you just need to know how it works
I'm playing FTB Lite 3, how do I enable retrogen? I've turned on "ReplaceVanillaGeneration=true" and "RetroactiveOreGeneration=true" in CoFHCore.cfg but it doesn't seem to be doing anything. Is some other mod doing the oregen?
I don't know what differences are between 1.7.10 ersions and 1.6.4 versions, but at least in the latter, the "RetroactiveOreGeneration=true" switch is only a master switch. In other words, turning it off prevents any and all retrogen from happening, regardless of what's configured elsewhere, and turning it on merely allows whatever is configured elsewhere to go through.
If you want ores to generate retroactively, you must specify this for each individual ore in its own configuration entry. For example, in 1.6.4 this is inside CoFHWorld-Generation.cfg and looks something like this:
Code:
thermalexpansion {
####################
# copper
#===================
# <UNIFORM> Generation settings for Copper; Defaults: ClusterSize = 8, NumClusters = 10, MinY = 40, MaxY = 75
####################
copper {
I:ClusterSize=8
I:MaxY=75
I:MinY=40
I:NumClusters=11
B:RetroGen=true
}
As you can see, there is an individual retrogen switch for this ore only, which in this case happens to be set to true. You need to check all individual ore entries - including the vanilla ones, because you have set "ReplaceVanillaGeneration=true" - and decide which ones you want active.
Finally, there is logic in place that prevents retrogen in chunks which have already received proper ore generation. If there wasn't, you would get new ores spawning everytime you loaded the chunk! It should work like this:
- Chunk was generated without CoFH Core installed, and you then install CoFH Core: all ores marked for retrogen at the time will generate once
--- If an ore was not marked for retrogen in this scenario, it is still eligible and will retrogen if you mark it as such later
- Chunk was generated with CoFH Core installed, and you later change retrogen settings for an existing ore: nothing happens
- Chunk was generated with CoFH Core instaled, and you later add a new ore and tell it to retrogen: that ore only will generate once
It basically sums up to CoFH Core saying: "Was I present when this ore generated? If no, it can retrogen once, and after doing so, it counts as me being present when this ore generated for all future checks. If yes, it is not allowed to retrogen."
