- It's tough sometimes to convince clients that the real world works a certain
- way and you can't do something another way. However, if he doesn't want a
- recognizable or fractal pattern then you can always use a real photo of
- clouds or something like that. Placing a bump map on your rectangle will
- distort the image so that even if you use a reflection map of someone's
- face you would not be able to see a face at all.
-
- If you use a subtle bump map using fractal noise pattern at 5-10%
- intensity, you may end up with an effect that is suitable.
-
- If your client wants it to flare, (that overused effect which shows
- glistening areas going all over the object) then you can use another
- technique:
-
- Create a graphic on black of white diagonal bars with soft edges (that
- go to black) and use it as your reflection map. You must parent all
- objects in your scene to a central point (including the camera) so that
- you can then spin your whole set around. The result will be a diagonal
- flare flashing across your object, and no recognizable or fractal
- patterns in the rectangular face. You can still use the bump mapping
- technique to slightly distort the flare.
-
- Since the camera moves with the object, the whole effect is static. (This
- can also work on gradated backgrounds as long as your spin is not on an
- angle to the gradation.
