Field Procedural Affector
Method #
This node affects a field’s velocities by attracting or repelling it using a procedural’s surface. The affector may apply as a force, which injects it into the simulation; or as a velocity modifier, which injects it each frame post-simulation without feeding into the simulation itself.
Parameters
These properties control the core behaviours of the node.
Parameter Details Direction
The direction of effect.
- Attract : The field is attracted towards the procedural surface.
- Repel : The field is repelled away from the procedural surface.
Velocity Scale
The scale of the applied velocity.
Affector Mode
The method by which the affector is applied to the field.
- Force : The results of the affector are added to the simulation as forces.
- Velocity Modifier : The results of the affector are added each frame after the results of the simulation, and not injected into the simulation itself.
Modulate By Temperature
The strength of the affector is modulated per cell by the temperature of the cell, so movement is stronger in hotter areas.
Modulate By Velocity
The strength of the affector is modulated per cell by the magnitude of the velocity of the cell, so movement is stronger in faster-moving areas.
