Rendering Sims Separately

[nelpiper]

Hello.
I have 3 sims in which 1 of them are fire and smoke and the other 2 are only smoke.
The fire sim cast light on the other 2 smoke-only sims. I like this interaction but I´d like to have control over all the sims.
Is there a way to render the sims separately from each other but still have the interaction of the light on the others?

Thanks.
