    Problem with big obj files

    I'm using Blender to make 3D models. I want to make a Landscape in the obj Format. My Problem is, that the File for 512*512 meters is 150 MB big. I have opened it with Notepad and there are six numbers after the comma. But I only Need centimeters and not nanometers. So I don't know, how to delete all these numbers.
    Here is a piece of the file:

    # Blender v2.78 (sub 0) OBJ File: ''
    # www.blender.org
    o Plane_Plane.001
    v -120.000000 10111.000000 1047.000000
    v -182.000000 10079.000000 1104.000000
    v -108.000000 10067.000000 1117.000000
    v -46.000000 10097.000000 1059.000000
    v -57.000000 10139.000000 988.000000
    v -131.000000 10154.000000 976.000000
    v -195.000000 10123.000000 1034.000000
    v -144.000000 10195.000000 904.000000

    And I really need to use the obj Format, because I want to work with the vertex data, and you can't make it with binary files (like fbx).

    I actually don't know how basically these facts are connected. But 150mb is a very small scene.
    During my last workflow I was working with a 2.5gb master scene.

      It would be better to make your landscape into a heightmap and use that with the landscape tools within UE4 since that will allow better performance in the game rather than using an imported mesh.

        I Need to make an obj, because I want to Experiment with the procedural mesh component. It has Features which the landscape component hasn't.

          You could use a find and replace command in any text editor for ".000000"

          But that shouldn't make any difference when the obj is in engine.

            I haven't thought about it. That's a good and simple idea. The file isn't going in the Engine, it goes in the code of a procedural mesh.
