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.
The pull force is a force which pulls particles towards the central axis of the vortex.
Pull force: controls the strength of the pull force.
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 follow force is a force which pulls particles along the central axis of the vortex.
Follow force: controls the strength of the follow force.
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 swirl force is a force which moves particles around the central axis of the vortex.
Swirl force: controls the strength of the follow force.
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.
