I'm jumping into the middle of your conversation so I hope you don't
mind....
Thank you for the wonderfully improved particle system!
I've never been able to get shaded balls to look quite like I wanted for
dust / smoke trails so on the weekend I tried using the "volumetric"
elements (e.g. clouds, fire, fog, volumetric clouds, etc..) as
primitives and they don't seem to work. If I understand the new
particle emitter correctly I must tell the emitter to use "objects" as
the emitter particles then make "objects" children of the emitter. That
works for me when I use "polygon" or "primitive" (e.g. sphere, cube)
objects but not when I use "volumetric" objects. Did I miss something?
Also, I noticed something else regarding the particles... the "local
gravity" seems to ignore the particle "mass" when calculating climb and
fall rates even though "local gravity" is shown as "in/s^2/kg". In
other words, with the local gravity set to z = -9 a 100kg particle seems
to climb and fall to the ground at the same speed as a 0.01kg particle.
Did I miss something?
Thank You,
Michael
