Blueprint a character with three-point light technique

hi, I want to apply a three-point light technique to a character using a blueprint and these lights should not affect other blueprints containing the same kind of characters with lights in the blueprint.

That will cost a lot, can very easily break immersion, and is a nightmare to do in anything but a static shot with someone facing 1 direction. Its not a bad idea, but, I wouldnt do it. Not bad practice, just mostly an unwalked road (To do intentionally, that is). You could place the lights just perfectly around the scene so lighting just happens to be coming from the right direction.

Thanks! actually, I want to try it for CG animation which contains 5 characters and I want Rim/backlight on the characters, and light should not affect other characters.
