If you're referring to the "ILM Mod," there's never been a copy on ModTheGalaxy, and many of the older mods from live have been lost, unfortunately.
The ILM mod doesn't have many fans around here, which may attribute to it's lack of presence and backup. As far as I know, despite what it claimed to do, all it really did was replace textures. There have been plenty of mods that go above and beyond what 'ILM' claimed to do, though I understand some people, possibly such as yourself, have nostalgia for the particular look and aesthetic 'ILM' provided.
While I personally detest the mod, I don't like pieces of our modding history to be lost to time. If anyone has a link to the mod or an old repository of it, feel free to post it to resources, or send it to me and I'll give it a proper resource entry.
