Thread: Help with terrain maps

    Post Help with terrain maps

    Hi all,

    I've got a problem with getting some terrain-map i created in Bryce, into a 3D game. As you can see in the picture below, you can see in the center part my height in the terrain map is terraced, i mean, it has a certain great value, and then it suddenly changes to a next value. I'd like to smooth that out. I've been playing around in Gimp & Photoshop, but i can get it smoothed. Given the amount of talent that visits here, i thought i might well ask for help here.



    thanks

    Try switching to 16bit mode and doing a blur or something. Then switch back to 8bit. Just an idea.

    Personally, I never had any luck blurring something like this...it just extends the terrace outward. I never tried 16 bit mode though.

    Working with a jpeg leaves something to be desired....

    but I pulled it into wilbur, selected the lowlands with the magic wand, then ran the deterrace filter, added 1% noise then deterraced again.

    Here is the 16 bit png.

    (also zipped, as I'm not sure if the forum supports 16 bit)

    Badger,

    Did you mess with Image->Adjustments->Levels in PS?

    Thanks a lot for the advice.

    The heightmap was actually created in Bryce & exported to a jpg file. As RobA suggested, i'll try an export to bmp, might yield better result.

    Will try it later tonight.

    i see, yet the current image doesn't use the full range of grays.

    I might get this to work by adjusting the levels, so the entire range from pure black to pure white gets uses. Any pointers on smoothing the histogram when i do that?

    thanks

    OK. Here is the 8 bit deterraced png from wilbur. This should be stretched the whole range.
