System: warp_mesh

Structural

Parameter	Default	Range	What it does
echo_orient	0	0 – 3	Which way the echoed copy is flipped before it is blended.
palette_steps	0	0 – 16	Quantizes the palette into this many flat bands; 0 leaves it continuous.

Modal

Parameter	Default	Range	What it does
zoom	1	0.5 – 2	Scale the previous frame is resampled at, per vertex; above 1 the image tunnels inward.
rot	0	-1 – 1	Turns per second the resample is rotated by, per vertex.
cx	0.5	0 – 1	Horizontal point the per-vertex zoom and rotation pivot about, in uv.
cy	0.5	0 – 1	Vertical point the per-vertex zoom and rotation pivot about, in uv.
dx	0	-1 – 1	Sideways offset of the resample, in frame widths.
dy	0	-1 – 1	Vertical offset of the resample, in frame heights.
sx	1	0.5 – 2	Horizontal stretch of the resample, independently of zoom.
sy	1	0.5 – 2	Vertical stretch of the resample, independently of zoom.
warp	0	0 – 2	Amplitude of the travelling ripple added to the resample.
warp_scale	1	0.1 – 4	Spatial frequency of the ripple; higher makes it finer.
warp_speed	1	0 – 4	How fast the ripple travels, as a multiple of its base rate.
decay	0.72	0 – 1	How much of the field survives each second, which is what sets the trail’s length.
deposit	1.6	0 – 8	How much light the source figure adds into the field each frame.
deposit_x	0.5	0 – 1	Horizontal position of the deposited figure, in uv.
deposit_y	0.5	0 – 1	Vertical position of the deposited figure, in uv.
deposit_radius	0.45	0 – 1	Radius of the deposited ring.
deposit_width	0.11	0 – 0.5	How thick that ring is; narrow reads as a wire, wide as a disc.
deposit_arms	0	0 – 16	How many arms the ring is broken into, as a real angular frequency; 0 leaves it whole.
deposit_twist	0	-2 – 2	Sweeps the arms into a spiral rather than leaving them radial.
deposit_spin	0	-2 – 2	Turns per second the deposited figure rotates by.
gamma	1	0.25 – 4	Shapes the field’s tone curve on its way out; below 1 lifts the mid tones.
wrap	0	0 – 1	Wraps a sample that leaves the frame back in at the opposite edge, instead of clamping.
darken_center	0	0 – 1	Pulls brightness down toward the middle of the frame.
brighten	0	0 – 1	Lifts the field’s bright end, MilkDrop’s own brighten switch.
darken	0	0 – 1	Pushes the field’s dark end down, MilkDrop’s own darken switch.
solarize	0	0 – 1	Inverts the field above its midpoint, so highlights fold back into shadow.
invert	0	0 – 1	Inverts the whole field.
echo_alpha	0	0 – 1	How strongly a second, scaled copy of the field is blended over the first.
echo_zoom	1	0.25 – 4	How much larger or smaller that echoed copy is.
hue	0	0 – 1	Where this scene reads from the palette, as a coordinate along it rather than a colour.
color_span	1	0 – 1	How much of the palette the field’s range covers.
color_center	0	-1 – 1	Shifts which part of that range lands in the middle of the palette.
saturation	1	0 – 1	Pulls the scene’s colour toward grey; 0 is fully desaturated, 1 is the palette’s own.
palette_mix	0	0 – 1	Crossfades from the preset’s palette to its second one; 0 is the first, 1 the second.
palette_contour	0	0 – 1	Draws a line at each band edge when the palette is stepped; 0 draws none.
brightness	1	0 – 2	The scene’s overall light level, multiplying what it draws before the composite.
