I'm hoping someone could tell me what I would need to do to adjust a refraction map that was created in a 3D program for compositing. Currently I can render out a refraction map, but I'm not sure how to composite, would just a blending mode work ?

You're going to need to talk to users of that 3D app, I should think. A refraction map won't do you much good in AE, AFAIK. You can use the output, which I assume is a grayscale movie, for various purposes with a number of different compound effects in AE but you won't find a specific "refraction filter." Reflections are a bit easier accoriding the cow's AE wonks. http://forums.creativecow.net/thread/2/926454
I've read about using normals for refraction. I know that compositing refractions is not common from what I've read from others. The first two links you've posted, return a 404 error :(
I'm taking a look at the refraction tutorial on Video Co-pilot which are one of the links you posted there is a plug in for using refraction maps with normals, I'll try that out see what I come up with, hopefully it works.
Search the index of AE tutorials for RE_FREAKING_FRACTION. It simply cannot be too difficult.
Childish is the wrong word !
Anyhow, how am I suppose to know if the information is even available or where the link, links too ? I'm well aware of the search function, I don't need you to address it to me.
Besides the information was not was I was after but I do want to thank the person for posting the links, I really do not know, where your comment came into the thread, but you do have the freedom to post, regardless if it was uncalled for.
