Hi Kang, welcome…
The stairs are because of using 8 bit (saving or loading).
Read this post for more info and solutions.

As for uploading of pictures, you can’t. :frowning: You must find some place to put them online, and link to them by placing the url between img and /img tags.

Cheers,

I try to all my effort. but stair situation leaves still, as you look picture.

        try: 1. I extract *.ter to WM and then use tconv.exe-->i made
                  16bit tif images. but still leaves a contour line.
              2.  extract .r16 file and change to file extension. then
                   Channels count = 1 
                   Depth = 16bit 
                   Byte order is IBM PC 
                   Header is 0 bytes. 
                   
                   open the file  above option in photoshop cs2.
                   but result is same.

Note that “seeing” artifacts on a greyscale image in a monitor, may be natural due to the color depth being used, graphics drivers, or other things.
Test things using your modelling tool, like you have done on your last image.
I am unable to help you much further than this, because I don’t have the right tools to test it myself.

Though, searching the forum, I found this Sticky topic, which may be of good use to you: From World Machine to 3D Studio MAX in 16-bit via TIFF/PNG (disable Color Management)
