Particle Wrangle

Runs your own GPU code on every particle (velocity, colour, damage) during the simulation.

Inputs: Particles: A stream of particles or rigid pieces.; Simulation State: The solver’s result. Pass it through meshers to the Simulation

Outputs: Particles: A stream of particles or rigid pieces.; Simulation State: The solver’s result. Pass it through meshers to the Simulation; Wrangle: Attaches this wrangle to a solver’s detail input.

Setting	What it does	Default
Source Mode	Code typed in the node, or read from a Text datablock	INLINE
Snippet	Procedural VEX-style particle code	# e.g. @v.y += 0.5
Script Text	Text datablock containing wrangle code
Stage	When the code runs: every substep, once per frame after the substeps, or on newborn particles	SUBSTEP
Run Order	Wrangles run lowest number first; equal numbers run in the order the graph lists them	0

Field Wrangle

Runs your own GPU code on every voxel of a Blaze grid (density, temperature, forces).

Inputs: Detail: Extra detail for a Blaze simulation: turbulence and field wrang

Outputs: Wrangle: Attaches this wrangle to a solver’s detail input.

Setting	What it does	Default
Source Mode	Code typed in the node, or read from a Text datablock	INLINE
Snippet	Procedural VEX-style grid field code	# e.g. @temperature += 1.0 * @dt
Script Text	Text datablock containing wrangle code
Stage	When the code runs: Forces (may write @v and @force), Substep or Post-Step (scalars only)	SUBSTEP
Run Order	Wrangles run lowest number first; equal numbers run in the order the graph lists them	0
