bist du dir sicher das dies von RW is? sieht eher aus we minecraft.... 
what do you mean @zfoxfire? to edit a chunk so that it gets converted to a new "biome"-type of thing?
In theory that is possible with the API I think
I think it is possible in theory as well. But I'm wondering if terrain in the Rising World version was generated by algorithm or done manually.
Sorry but in this form is nothing known to me .... why this construction? I leave with some know how one gets this also surely .... but there must be really good ... to put alone an island it was already very difficult for me .... 
As it is a very big thing ... like my biggest project so far (Dubai) but I already at a larger and it will be the largest of my life since one can not be bigger at rising world (315x315x260 blocks) .. .. think about you well .... it's a lot of work in it .... you can only tackle this mega project if you are also quite sure to end this ... believe me ... I work on the new project Now for about 3 weeks .... alone at the roof .... and the lust fades ... but I've got me in the head set it also to end ... if you do it then my full respect and good luck the It also succeeds ...
