From my experience, you need to increase standard forces for pretty much everything (Cloth, Fume, Phoenix) , except PFlow and standard Max particles .
Tyflow is no different then others in that case.
I guess, it's because "normal" particle behavior is much more affected by forces, then any type of simulation that gives them weight, and whole lots of other parameters.
But it's working fine, with exception of vortex, that really behaves crazy (as I mentioned in other thread), but we have TyVortex.
That's like irony of the destiny... I had big troubles understanding basic vortex, and after a years I get a hang of it, it 's not working anymore
Also, I haven't got time, but there's some really old forces plugins, that behave similar like Vortex (but with more "reasonable" controls).
I think it's name is Phasor, and there is one more...
Really curious to see if they work with Tyflow....
