Hi all,
using WM 1.25 St-Ed., I just built a very simple world:
[list][]1st device is a perlin noise generator with standard settings (10013 random seed).
[]This is connected to a Clamp device, set from 0.100 to 0.200, Clamp Style is “Clamp”, and not normalizing the input.
[*]This goes to a second Clamp device, with which I do nothing but hit the “Find Extents” button.[/list:u]As result I get the range from 0.120 to 0.190, which I believe is correct because the 1st Clamp device did not normalize the terrain, so it didn’t span the full range.
Next I go back to the settings of the first Clamp device and turn Normalize Input on. Then, hitting “Find Extents” again in the second clamp device, I get the height range from 0.090 to 0.190, which - imho - is clearly wrong.
(It also looks to me as if the precision of these numbers was limited to only two digits after the decimal, but that is just a guess.)
So unfortunately, this renders the work-around for learning the true terrain height span discussed in the other thread unreliable… :oops:
