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.
