Hello , I have a map I did lot of time ago with FT , I liked it but I wanted to add some minor changes , like smaller islands here and there, SO I focused on a region and I picked an arcipelago area, there are lots of nicely shaped fractal islands there, but whenever I go in with the brush , large or small, rise terrain , lower terrain rise or descrease roughness, the resutls are in more or less blobs of terrain and not smaller fractal islands... Is thee a way to break or add a noise to coastlines?

Thankyou , btw , I remember I followed a series of tutorial on how to add also the erosion on the fractal terrain generated map , is it that too? Or there are others? I don't remember...
http://fracterra.com/ThereandBackAgain/index.html uses Wilbur and FT together. I don't recall if there is a specific tutorial for erosion in FT, but it does have many of the same features as Wilbur as far as erosion goes. Unfortunately, FT's incise flow only takes place in the offset channel and not the prescale offset channel.
About that link , the link inside there is not working ...

Also whenever I Fill Basins, Incise Flow. the Wilbur program crashes ... is there a way to prevent this?

I seem to have missed some links in those documents. Any place that reads "http://www.ridgenet.net/~jslayton/" should read "http://fracterra.com/".
Is the crash during Fill Basins or during Incise Flow?
How large is the surface that you are trying to process?
Are you running the 32-bit version or the 64-bit version? The 32-bit version has some fairly hard limits on the size of a surface that it can process with Fill Basins and the failure behavior is to just crash with a stack overflow. The 64-bit version has the same problem, but the failure point is much farther away. I should probably convert it to a non-recursive form that will fail more gracefully, but I don't really have time for much in the way of non-paying activities anymore (with the possible exception of sleep).
Oh apparently I was using still a Wilbur version from 2014, glad to see you updated, I downloaded the new one and so far worked, proceding with the tutorial.
K I met another issue, when I tried to export a heightmap from FT 3 I did load a grayscale map , and then went to save as bmp , png or other , but I usually get either an error or a crash ...
I would like ot have at least an export of 16k but isn't working.

I have 32 gb ram btw.
FT3 is a 32-bit program and can't support an image of quite that size, sorry. 8k is usually around the best that FT can do.
Yes but I put 8 k and crashed, Also I have all maps outsourced by FT3 that are 16384x8192 but I dunno how I did , as like I lost the know how ... any idea of why this can be fixed? There must be a way because I have all maps there in that size but I dunno how I did them lol ...
