So I'm going to say this from now on, because clearly this is a benefit for normal maps.
Here's the benefit - you do not need to specify the correct depth to achieve a specific shape that you were using in the modeling tool.
That's good.
The downside is that is the ONLY shape you can get with the normal map you have. If you want any variation of that, you have to get a new normal map. With a bump map, you don't.
Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
