Map Converter v1.1 released
I've just posted a new script which searches your scene for bitmap textures and then converts them to memory-mapped .map files for use in mental ray.
I won't be doing anymore work on the script because Max doesn't really like .map files, and there is no way to use them properly in Max. At the moment, the script is fine if you've applied a bitmap texture to an object and all of the settings are default (ie UV tiling, offset etc.) Using .map textures can make a noticeable difference in rendering times if you are doing large renders with large textures.
