Not if you use the lights from the flames themselves to fill in the areas behind the pillars. ![]()
If that's not what you're aiming for and you really want good lights on the flames, only extend the main fill light maybe halfway past the pillars, use an additional fill light behind, and then each light from the flame is only the second light pass on most faces aside of maybe part of the pillar (which would be at 3) if you size them well.
I don't expect you'll get it right on the first or second try, and neither should you.
It's really tough to get the perfect balance of illumination and light count/shadow tris, but when you do hit the mark, the results really pop out at you... almost literally.
