Which costs less, IFL or particles?

I'd like to implement a chandelier that contains 8 candles, and hence 8 candle flames. I'm debating whether to try and implement the flames as 8 individual IFLs or as 8 particle emitters.
Just wondering if anyone has insight into which is probably more processor-intensive.

Using IFLs would be nice since I'd like to turn off the animation while the player isn't in the vicinity of the candles. A static IFL would look better than a particle emitter turned off if the player somehow could see it...

Thanks, Matt. I suspected as much...just looking for some thoughts before we try to do a bunch of work to test this.Using IFLs would be nice since I'd like to turn off the animation while the player isn't in the vicinity of the candles.

It would be harder LOD out the particle systems.

You could possibly also LOD the IFL out whenever the Player is further away since a static candle flame would look decent at a distance.It would be harder LOD out the particle systems.

Yeah, that's the idea...I'll have to look into how to do that, thanks...

today 2009 and games like TGA 4 uses ifl for fire in the game.

And it is easy to organize them using dds (if TGE supports dds).

Texel lods are also called mip levels.And it is easy to organize them using dds (if TGE supports dds).
