I've seen the example and I have my bumpmapping on a separate layer. I set the parameters x and y of the bumpmapping effect like so...
(Spaceship.x/LayoutWidth)*100
(Spaceship.y/LayoutHeight)*100
This 'should' put the bump map at wherever my spaceship is, but instead the light is offset. The more I move to the right for example, the more the light move further to the right of my spaceship. The same in all directions. Its only ever correct in my starting position.
It seems maybe there is some kind of light direction that's not definable maybe?
Is there a way to position the light 'source' exactly where I want it?
Maybe there is another alternative this?
Cheers
