Steven,
In order to do an "inverted" bump map, just reverse the colours of the
original cel, gif, tga, or whatever that you're using as a bump map. In other
words, if you have a cel consisting of white dots on a black background, just
reverse the colours to black dots on a white background.
Sounds relatively easy to do but in practice, with an image consisting of 64
shades of grey or something like that, it can be a little more complicated. I
suggest you use Animator Pro to do this.
Hope this helps,
Danny…
