Thank God! You didn’t blame me to steal you idea. By the way after watching Inception, I knew the trick how to steal someone’s idea getting into his/her dream. ;)

I don’t know Spencer which tut you are saying about, but my this tut is about compositing 3d renders using object IDs and this is the successor of my previous tut RGB Pass compositing, and it was very much relevant to put it here since object id thing makes the life more easier for those who use 3ds Max instead of Maya. And I guess you have not seen RGB pass compositing tut anywhere else. However you can do some R & D on net to prove me wrong and make you happy, if you could do so.
AeTuts+ is a great site for both learners and authors. I have never seen such a great site and its incomparable. Andrew kramer’s much hyped Videocopilot is at 6831 in the traffic ranking of Alexa but AeTuts+ is at 578 in the traffic ranking. See the difference yourself. And this site doesn’t publish bad tuts at all. And if it publishes a tut, it means its original, delivers good knowledge, not published anywhere else and ofcourse will be paid in the beginning of the next month. I hope you have now got the answer of your question (doubt) till your satisfaction level ;)
