Motivation
Some mods contain useless ores and other worlgen blocks. In case if you forgot to disable those blocks or mod doesn't allow to do so, this mod exist to do the job.
Configuration
Add blocks you want to replace in config file 'blockreplace.cfg' in such format:
S:replaceMap <
modid:blocknametoreplace=modid:blocknamereplacement
...
>
For example:
S:replaceMap <
minecraft:dirt=minecraft:stone
minecraft:grass=minecraft:stone
Magneticraft:thorium_ore=IC2:blockOreCopper
minecraft:red_flower:3=minecraft:red_flower
>
You also can specify dimensions to replace blocks in:
S:dimensionMap <
modid:blocknametoreplace=dimensionids
...
>
For example to replace dirt blocks in Nether only:
S:dimensionMap <
minecraft:dirt=-1
>
Or in Nether and The End:
S:dimensionMap <
minecraft:dirt=-1,1
>
If block is not listed in dimensionMap then it should be replaced in all dimensions.
If you want to replace blocks in already generated chunks then set option B:replaceBlocksInGeneratedChunks=true
