hello,
i’m working on a particles system that simulate smoke from a mecha robot.
my probleme is that if i make walking the mecha, smoke velocity is modified and goes sometimes faster than the mecha…
i dunno how to correctly modify parameters…
i want to preserve a local direction from axe of mecha.
You should check out Particle Emitter (especially the difference between world velocity and local velocity, and “Emitter Velocity Scale” that might create the problem you’re describing).
Also look at Particle animator (specifically the force parameter).
To make smoke look just right you need to combine those. Use force on the particle animator to make the smoke go down (simulating gravity) or up (if it’s supposed to be a gas that rises, like chimney smoke). Use local velocity to achieve what you’re describing… and make sure the Emitter Velocity Scale is set correctly.
ok,
emiter velocity scale was to big (1)
thanks
