[Solved]Excluding character from scenes lightmap

Quick question, do you know if it is possible to exclude a specific character from the lightmap of a scene ? (or all of scenes for that matter)

To put it to perspective, let's say that a character is a being emmiting light (ghost, screen, hologram etc...) and you really want it as a character, not an object, since you want him to follow the main character, or even be playable.

having him changing tone when entering the dark part of the lightmap breaks the imersion quite a bit.

Any ideas ?

thank you in advance

Thanks a bunch !
