Wilbur - Height Mapping and Map Pixilation

[MorelockTheWarlock]

Hi all,

I have a couple of questions I'm looking to get some help with. In no particular order:

1. How do I go about setting maximum height for an imported map in Wilbur? I have a greyscale height map that that increases in increments of 3000 feet. I assume by setting the height of the highest peak, Wilbur is able to infer everything else between that maximum and sea level.

2. I've been trying to follow waldronate's instructions here , however I'm a little confused on step D:

Filter>>Noise>>Wilbur Add Noise with amplitude decreasing at every step: start at around 10% of the total altitude and decrease by half at each step (e.g. 1000 altitude would get 100 at the first step, 50 at the second, and so on).

Am I supposed to have all land selected and then run the noise (100% > 50% > 25% > 12% > etc.?) or am I supposed to select the highest altitude increment (run noise at 100%), then the next highest (noise at 50%), and so on until reaching sea level? I suppose I need clarification specifically on:

start at around 10% of the total altitude and decrease by half at each step

Additionally, does Wilbur allow you to make a selection based upon height? E.g. can I select everything specifically within 5,000 - 6,000 ft.?

3. Finally, the map (attached below) I'm working with is part of a larger, global map. Because it was cut directly from that parent map the smaller one is looking pretty blocky/pixilated. I'd like to have something more organic looking however I'm not sure what the best way of doing that would be. Should I first try to blur the edges in GIMP or will erosion and noise through Wilbur eventually wear it down? In either case, what would be the best way of doing that?

Thank you!
