  • Manually Creating Mip Maps

    You can avoid the manual steps below by using this script I wrote:

    Download maxscript mg_mr_tools_v02.zip

    Manual Process

    To create Mip Maps, Mental Ray comes with a command line executable called imf_copy.exe. This can be found in:

    C:\Program Files\Autodesk\3ds Max 2011\mentalimages\imf_copy.exe

    (path may vary depending where 3DS Max is installed)

    Older versions of 3DS Max did not come with this file, but I have heard you can get it from a demo version of XSI or Maya.

    Once you have located the file, you can run it manually from the command prompt/shell. To launch the command prompt/shell, go to Start/Accessories/Command Prompt.


    This will launch a new window with the Command Prompt. For those not familiar with DOS, I’ve written the commands below.

    To open the folder with your file type in cd <your path>:

    cd “C:\Program Files\Autodesk\3ds Max 2011\mentalimages\

    <press enter>

    Next, type in:

    dir <press enter>

    This will give you a list of files in the folder, and you should see imf_copy.exe.

    Now that you have confirmed that you have the file, you can run it.
    From the mental images folder, you can run the command as follows:

    imf_copy -vrp <path><source filename> <path><target filename>

    You can type imf_copy and hit enter to see a list of all the possible parameters.

One Responseso far.
