Glad I could help.

Well, i still have some problems with the world generation.

Nearly everywhere i find these huge chunk cliffs:

(Overworld and custom dimension.)

 

Here is my new Chunk Provider:

May I ask you to send me whole code for your dimension. Could you upload it to the mediafire or github? If you did so, I would be really grateful since you will really help me. Things have changed from 1.6.4 to the 1.7.2 in a great deal.

 

Thank you!
