one of the coolest things I find is to meet new people and check out their workflows and templates , so I wanted to see how the sfx/sound designers arrange pre dubs, specifically with regard to tracks intended for LFE.
Eg in the past I may have splits such as cars, weapons, household etc with a specific pre dub for LF. The idea being that a dedicated VCA could be available for more or less of that. It works, its pretty clear but it does separate lf elements from their parent pre dub group. So for the next feature I was considering adding 2-3 mono tracks to be dedicated LFE sweeteners per pre dub (maybe not inc house hold etc) but def for impacts, vehicles , weapons etc
I'm on the 'simple' (but you can call it 'cheap') side. Usually just one or two dedicated mono tracks per project. I don't like sending stuff from regular tracks to the LFE (except for the upmixed music), because in that case I don't have an easy overview of what has been sent and when. With a dedicated LFE track(s), you see at a glance the temporal and amplitudal structure of your LFE usage.
I tend to use a handful of specific lfe tracks (filtered between 100 and 120 depending on what sounds best - I am not too pedantic)
the I sue Auxes to derive through something like a dbx box or lowender/lowair etc.
ButI think I may create specific lfe tracks per pre dub , so that they groups correctly on a via and so if I end up printing some I will have the printed lfe too.
I never use the pro tools panner to send to lf. May work ok in the 6 track but it all turns to custard when you down mix as what you are in effect doing is adding a duplicate to the stem that is only filtered in the processor (CP650 etc)
