I'm compiling some new helpfull info for the editor and would like you guys to help.
one think I noted about the AK bmp2map (which I like better than the integrated elv import in TE) is the color scaling.
to set correct elvations in the grayscale image:
in the color picker (doubleclick forground color)
the RGB ranges R, G, and B in color picker selection) the number to the left matches the actual elevation that will be set in BMP2MAP, i.e. R=5 G=5 B=5 the alt of that pixel will be 500-550 ft (approx)
This should help to make smooth grades from water to land, ( I use 3-5 off the water)
