Hello, me as a fellow developer know how much we all try to fight lag. So I decided to share my discovery, in case people have not discovered this themselves, in case they make their games in nontraditional ways like I have done.
In my game, I would normally keep the character model separated from the player model. My reasoning to this was that I enjoyed having reflectance beyond 1 for characters, as these effects where no doubt, cool.
However earlier today I have discovered this issue with this. It seemed to lag up the lighting engine twicefold on my end (though I must say I do not know how this will impact everyone else).
Here are some screen grabs to show the difference on the character model in the player model, and vice versa.

Img2: Character Model Inside Player Model
This, though could be a very uncommon issue, should be an issue that many devs know in case they did what I did. Which was separate the character model from the player model, to obtain cooler reflectance.
Hope this helps someone out there or at least informs someone of this issue that they may of not know.
Have a nice day,
