Simple LOD Manager Mesh to Mesh (Smoothly Fade)

Hi, Unity Community ! I have a question about a script that is on Unify C. and the script name is "Simple LOD Manager" i want to use this script to test some of my project's .

Unify Community (Simple LOD Manager)

But i don't know how could be possible to make a "Fade Effect" like in the newer games ? I don't want just switch to another mesh to another... i want to smoothly fade into the next/previous mesh . But how could it be made or is it not possible in Unity "Indie" ?

Thanks in advance :)
