Thinking about that some more, there is a variation on that benefit that is likely even more important.
If you have a prop with a bump map for the purpose of altering the virtual shape, and you SCALE the prop, you have to scale the bump depth as well, or you end up with a new virtual shape!
WIth a normal map, you do NOT have to adjust anything - the virtual shape will automatically be scaled as well. That's a very good point and I'm glad to see it.
For that reason, and that reason alone, I now believe that normal maps are better than bump maps for some things. For other things, like my virtual tiles on a single polygon, the bump map is better.
Fugazi gets the full prize, guys.
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)
