System: warp_mesh

Structural

Parameter	Default	Range	What it does	Group
deposit_arms	0	0 – 16	How many arms the ring is broken into, as a whole number of arms; 0 leaves it whole.	shape
echo_orient	0	0 – 3	Which way the echoed copy is flipped before it is blended.	post
color_source	0	0 – 1	Where the field takes its colour: 0 the deposit’s own angle, 1 the light it has built up.	colour
palette_steps	0	0 – 16	Quantizes the palette into this many flat bands; 0 leaves it continuous.	colour
palette_contour_style	0	0 – 3	Which line the contour draws: 0 a soft darkening, 1 a hard one, 2 a soft ink, 3 a hard ink.	colour

Modal

Parameter	Default	Range	What it does	Group
zoom	1	0.5 – 2	Scale the previous frame is resampled at, per vertex; above 1 the past is magnified and the image travels outward.	motion, main
rot	0	-1 – 1	Turns per second the resample is rotated by, per vertex.	motion, main
cx	0.5	0 – 1	Horizontal point the per-vertex zoom and rotation pivot about, in uv.	shape
cy	0.5	0 – 1	Vertical point the per-vertex zoom and rotation pivot about, in uv.	shape
dx	0	-1 – 1	Sideways offset of the resample, in frame widths.	motion
dy	0	-1 – 1	Vertical offset of the resample, in frame heights.	motion
sx	1	0.5 – 2	Horizontal stretch of the resample, independently of zoom.	shape
sy	1	0.5 – 2	Vertical stretch of the resample, independently of zoom.	shape
warp	0	0 – 2	Amplitude of the travelling ripple added to the resample.	shape, main
warp_scale	1	0.1 – 4	Spatial frequency of the ripple; higher makes it finer.	shape
warp_speed	1	0 – 4	How fast the ripple travels, as a multiple of its base rate.	motion
decay	0.72	0 – 1	How much of the field survives each second, which is what sets the trail’s length.	light, main
deposit	1.6	0 – 8	How much light the source figure adds into the field each frame.	shape, main
deposit_x	0.5	0 – 1	Horizontal position of the deposited figure, in uv.	shape
deposit_y	0.5	0 – 1	Vertical position of the deposited figure, in uv.	shape
deposit_radius	0.45	0 – 1	Radius of the deposited ring.	shape
deposit_width	0.11	0 – 0.5	How thick that ring is; narrow reads as a wire, wide as a disc.	shape
deposit_twist	0	-2 – 2	Sweeps the arms into a spiral rather than leaving them radial.	shape
deposit_spin	0	-2 – 2	Turns per second the deposited figure rotates by.	motion
gamma	1	0.25 – 4	Shapes the field’s tone curve on its way out; below 1 lifts the mid tones.	light
wrap	0	0 – 1	Wraps a sample that leaves the frame back in at the opposite edge, instead of clamping.	shape
darken_center	0	0 – 1	Pulls brightness down toward the middle of the frame.	light
brighten	0	0 – 1	Lifts the field’s bright end, MilkDrop’s own brighten switch.	light
darken	0	0 – 1	Pushes the field’s dark end down, MilkDrop’s own darken switch.	light
solarize	0	0 – 1	Inverts the field above its midpoint, so highlights fold back into shadow.	colour
invert	0	0 – 1	Inverts the whole field.	colour
echo_alpha	0	0 – 1	How strongly a second, scaled copy of the field is blended over the first.	post
echo_zoom	1	0.25 – 4	How much larger or smaller that echoed copy is.	post
hue	0	0 – 1	Where this scene reads from the palette, as a coordinate along it rather than a colour.	colour, main
color_span	1	0 – 1	How much of the palette the field’s range covers.	colour
color_center	0	-1 – 1	Shifts which part of that range lands in the middle of the palette.	colour
coverage_threshold	0	0 – 1	In level mode, the coverage a pixel needs to hold the ink: at or above it the palette’s colour, below it the backdrop. 0 is off.	light
saturation	1	0 – 1	Pulls the scene’s colour toward grey; 0 is fully desaturated, 1 is the palette’s own.	colour
palette_mix	0	0 – 1	Crossfades from the preset’s palette to its second one; 0 is the first, 1 the second.	colour
palette_contour	0	0 – 1	Draws a line at each band edge when the palette is stepped; 0 draws none.	colour
palette_contour_ink	0	0 – 1	Where along the palette an ink contour takes its colour; unread by the two black styles.	colour
brightness	1	0 – 2	The scene’s overall light level, multiplying what it draws before the composite.	light, main
