Hello!

 

When i change this: 

if((d15 += d16) > 0.0D) 
  b[j3 += short1] = Blocks.stone;

 

to this:

if((d15 += d16) > 0.0D) 
  b[j3 += short1] = BlockHelper.flylightStone;

 

It will generate the modded stone as the grass and dirt, I have no clue why!

 

If I leave it, it will generate fine but with vanilla stone.. (Obviously)

But I have no clue why it wont let me change just that var to suit what I need.

 

Full chunk provider:

You mean the grass and dirt are not spawning on top of it or the actual stone is only the top layer?  Personally I replace the stone in the new generate terrain function that you can override in your biome.  I think because the top and filler blocks only spawn on vanilla stone you have to do it that way.  Copy the genTerrainBlocks from the vanilla BiomeGenBase class, put it in your biome and change the vanilla stone to your stone in that as well.
