The tyVortex helper can be used as an alternative to 3ds Max’s Vortex spacewarp, within a flow. It applies circular forces to particles along an axis.
Vortex force: controls the vortex force applied to particles, tangential to the vortex central axis.
Pull force: controls the pull force applied to particles, which pulls particles towards its central axis.
The axial influence extends outwards from the vortex’s vertical axis.
Distance: particles within this distance will be fully affected.
Falloff: the effect on particles beyond the base distance, but within this falloff distance, will diminish according to the inverse-square law.
The radial influence extends outwards from the vortex’ center.
Distance: particles within this distance will be fully affected.
Falloff: the effect on particles beyond the base distance, but within this falloff distance, will diminish according to the inverse-square law.
CW/CCW: controls the direction of the vortex (clockwise or counter-clockwise).
Force relative to distance: controls whether the force applied to particles will be relative to their distance to the vortex.
Force relative to axis: controls whether forces applied to particles will be constrained to ensure that particle trajectories remain tangential to the central axis of the vortex. Turning this on will help ensure particles move in a perfect circle around the central axis regardless of their velocity, rather than being flung away, especially when “Force relative to distance” is turned on.
Icon size: controls the size of the tyVortex icon.
