Fluid AffectorApplies a fluid simulation to a field.
This node applies a fluid solver to the velocities of the field system, creating eddies and swirls like a gas or liquid. This solver uses the grid-based Navier Stokes method, maintaining incompressible pressures using multiple iterations of a process over the field’s voxel grid, and can have a sizeable performance impact with high-resolution fields.
These properties control the 3D transforms of the node. Transforms will generally be inherited by child nodes, although they can be ignored through the Inherit Transform Channels attributes.
|Position X||Move along the local x-axis.|
|Position Y||Move along the local y-axis.|
|Position Z||Move along the local z-axis.|
|Rotation Heading||Rotate around the local y-axis.|
|Rotation Pitch||Rotate around the local x-axis.|
|Rotation Bank||Rotate around the local z-axis.|
|Scale X||Scale along the local x-axis.|
|Scale Y||Scale along the local y-axis.|
|Scale Z||Scale along the local z-axis.|
Toggle which transform channels should be inherited from the parent node. By default, all transforms will be inherited.
|Position X||Toggle inheritance of the X Position from the parent.|
|Position Y||Toggle inheritance of the Y Position from the parent.|
|Position Z||Toggle inheritance of the Z Position from the parent.|
|Rotation Heading||Toggle inheritance of the Rotation Heading from the parent.|
|Rotation Pitch||Toggle inheritance of the Rotation Pitch from the parent.|
|Rotation Bank||Toggle inheritance of the Rotation Bank from the parent.|
|Scale X||Toggle inheritance of the X Scale from the parent.|
|Scale Y||Toggle inheritance of the Y Scale from the parent.|
|Scale Z||Toggle inheritance of the Z Scale from the parent.|
|World Position Only||Inherit the world position from the parent only, rotation and scale will be ignored. Overrides above properties.|
|Inherit Time||Toggle inheritance of time from the parent.|
These properties control the core behaviours of the node.
|Simulation Speed||Controls the speed of the fluid simulation.|
|Vorticity Confinement Scale||Controls the amount of vorticity confinement, which increases the number of small swirls in the fluid system.|
|Diffusion Amount||How much the field colours are diffused to neighbouring voxels.|
|Velocity Dampening||How much velocities are dampened and averaged across the field system.|
|Solver Iterations||How many times the fluid system solver is run. Higher values improve accuracy, but lower performance.|
