    Hi there,
    I am new to Unity3D.
    I got a problem now: I have no idea how to open an image and import it at runtime to be a texture of a certain mesh.
    Let me explain the problem in details:
    I want to import an image at runtime to be a texture. And the image is from other location on the disk(not in Unity project folder). I am using the EditorUtility.OpenFilePanel() to get the path right now. But I do not know which function can be used to load the image via the path.
    I have tried functions in Resource class, WWW class and AssetDatabase class.

    Could anybody please tell me how to do this?

    Thanks a lot!

    Use the WWW class with the file:// protocol.

    If you are also looking for a document browser to let the user select a file, I believe there is one somewhere on the wiki.

    Thank you!
    The problem is solved!
    I did not realize that I should use file:// protocol.

    www = WWW("file://" + File_Name)
    Face.renderer.sharedMaterial.mainTexture = www.texture

    Glad you got it working!

    Just an fyi: it's bad practice to use protected keywords with a case shift for variable names. It's just a little thing, but in programming it's always the little things that cause you stare at the screen for hours on end wondering why a piece of code isn't working correctly.

    Ye, indeed! I think I should be careful in that.
    And I got another question here if you can do me a favor:
    I wanna choose a file from my disk, and I think function EditorUtility.OpenFilePanel from UnityEditor class is a good choise.
    However, it has a problem when building, which is "Namespace 'UnityEditor' not found, maybe you forgot to add an assembly reference"
    Do you have any good ideas about selecting a file from disk and then return a path?

    Again, thanks a lot!

    Not saying your wrong, and I'll keep it in mind, but that is how the unity scripting reference does it.
