SplatWarp

3Dv1app

Overview

Pushes splats around — drift, wind, swirl, scatter. On the default sweep field the push blows from your placed ▶ start point toward your ⏹ end point (click them in the 3D viewer) — wind you can aim by clicking twice. noise swirls everywhere; distance pushes away from the start point (explode) or, negative amount, pulls toward it (implode); axis shears along X/Y/Z. amount is the push in metres — keyframe it to animate. A Directed region limits it to one object. Warped splats emit motion, so they blur correctly in the 2D comp.

How to

How-to

Put it after a SplatTransform.
On the default sweep field, click the ▶ start and ⏹ end points in the 3D viewer: the push blows from one toward the other.
amount is the push in metres; keyframe it to animate. distance with a negative amount implodes.
Warped splats carry motion, so they motion-blur correctly in the comp.

Output	Type
out	Scene

Parameters

Parameter	Type	Default	What it does
field	Choice	sweep	What shapes the push: `sweep` (blow start → end), `noise` (swirl everywhere), `distance` (out from the start point — negative amount pulls IN), `axis` (shear along X/Y/Z). `sweepnoisedistanceaxis`
amount	Float	1.0	The push strength in metres. Keyframe it 0→N to animate the blow-away; negative reverses the direction.
start_x	Float	0.0	The ▶ start point's X — click it in the 3D viewer with `place start`.
start_y	Float	0.0	The ▶ start point's Y — click it in the 3D viewer with `place start`.
start_z	Float	0.0	The ▶ start point's Z — click it in the 3D viewer with `place start`.
end_x	Float	0.0	The ⏹ end point's X — click it in the 3D viewer with `place end`.
end_y	Float	1.0	The ⏹ end point's Y — click it in the 3D viewer with `place end`.
end_z	Float	0.0	The ⏹ end point's Z — click it in the 3D viewer with `place end`.
noise_scale	Float	1.0	The noise field's feature size, world units — small scatters finely, large heaves in slow lobes.
seed	Int	1	The random pattern's starting point. Change it for a different pattern of the same character; keep it to reproduce a frame exactly.
radius	Float	1.0	Distance field: the push fades out by this radius from the start point.
axis	Int	1	Axis field: which axis the shear runs along — 0 = X, 1 = Y, 2 = Z.
axis_from	Float	0.0	Axis field: the coordinate where the shear begins.
axis_to	Float	1.0	Axis field: the coordinate where the shear ends.
region	Choice	off	Limit the warp to a box or sphere so it moves one object, not the world. `offboxsphere`
region_min_x	Float	-1.0	Region box: the X of the near corner, world units.
region_min_y	Float	-1.0	Region box: the Y of the near corner, world units.
region_min_z	Float	-1.0	Region box: the Z of the near corner, world units.
region_max_x	Float	1.0	Region box: the X of the far corner, world units.
region_max_y	Float	1.0	Region box: the Y of the far corner, world units.
region_max_z	Float	1.0	Region box: the Z of the far corner, world units.
region_center_x	Float	0.0	Region sphere: the X of its centre, world units.
region_center_y	Float	0.0	Region sphere: the Y of its centre, world units.
region_center_z	Float	0.0	Region sphere: the Z of its centre, world units.
region_radius	Float	1.0	Region sphere: its radius, world units.
disabled	Bool	false	Bypass: the node passes its first input through untouched (D in the graph). The knobs keep their values for when it comes back.
label	Text		A note shown under the node in the graph — what this node is FOR. Never affects the render or the cache.
hide_input	Bool	false	Draw the node without its input wire — a tidy graph for a node whose source is obvious (a Dot, a viewer tap).
