Quote - 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.

A prize how marvelous :) though I have a small question.  I did try a range of values for the bump map, without magically stumbling on the right value.  Is there any way of calculating the correct bump value, or is it educated guesswork? John
