Hello,
this beautiful program has this ‘lousy method’ of positioning the overall perlin.
For users of Bryce, there is a simple method called tile north, south, …
I would prefer a method like move perlin north by 95% and east by 38% relative to the current view.
Oshyan mentioned that in 1.0 for calculating the devices a larger area will be used. Therefore it should be possible to have a little preview window of the surrounding area 
Don’t hit me,

As you can see in the development diary, there should be an explorer mode (screenshots here and here) in the next version.
Otherwise you can try this : Double click on your perlin noise, turn on “Enable distorsion input”. Click OK, and link a Constant generator (Heighmap Operators > Generators), set with full height, to the newly created input on the perlin noise.
Simpy play with Strength and Direction to place the perlin as you want.
Hope this helps 
Rhalph, that’s just mean, teasing us like that. :lol:
