Summary: Ask all your nooby normal mapping questions in this thread, and we'll compile the info in a sticky to lower the level of noise on this subject and make things clear once and for all. I just say one thing to those wanting to volunteer answers: Get your facts right. I'm up to here with people trying to educate who have no idea what they're talking about and just make the situation worse, like saying that the low and hipoly models shouldn't intersect or some messed up stuff like that. Sorry, you guys just make the situation a lot worse.
Long rambling version of the above:
ok.. this... wtf...
I know there are moments when I don't understand shit of something and have such a lack of confidence in that subject that I just want to be let through the thing from step one. So I can understand that whole deal. It's like when I'm in bed with a woman, I still didn't figure out what goes where. You're right, Alex, there should be some sticky, if only to shut people up about this stuff because the same questions are answered I feel several times a week. Oh and it can be nice to be helpful. I just remember now how a lot of the people that now teach this stuff needed a hell of a lot of teaching themselves.
OK, let's do a new take on this. Of course I and some of the more experienced guys can give you all the information you need, we just think there are things so obvious you don't need to hear them. Let me get a sense of where the most nooby of the noobs are, ok? And let me understand if you're just damn lazy, or if you're actually making an effort.
So I'll try out some random questions just to test the waters.

how do you go about re-building the low poly model on top of the high poly one if the high poly one is way too many polygons for your computer to handle?

Don't you understand that you can just use a lower subdivision level of the hipoly that runs fine in the viewport? I'm not asking to insult you, I really want to get an idea of where you guys stand here. Feels like being one of those TV cops trying to track down a murderer by psychologically evaluating his crimes.
ok noobs, do you understand and can you visualize the direction that rays travel from the lowpoly to scan the hipoly model during processing time? This is vital.
What do you feel are the slowest steps of the whole modeling and generating process?
Do you have the necessary viewers/viewport shaders you need to properly check your results?
What kind of timeframes do you work with and what kind of timeframes would you LIKE to work with?
Where exactly does it fail for you?
And so on. Don't be embarrased to ask stupid questions. I might make fun of you, but hey, you'll get the information you want.
Also, let me tell you this, so you won't think that you're a complete moron to fail at this stuff: Some of the guys you look up to and who teach you about normal mapping now were completely retarded on the subject and took like years to understand the basics some of them.
I figured out all this stuff 6 years, so there's no question you won't get answered, just make at least a half-hearted attempt at prose. State which software you're using, what you're trying to do versus the results you're getting, and include illustrative images as needed.
quick addendum: Don't start moaning like a crybaby about how a poster hates you if you don't get the answer you wanted. Most likely you have to rephrase or elaborate on your question.
