Fractal skies¶

NeoForge 26.1.2 and 1.21.1.

A sky drawn per pixel by Fundamentum's fractal shader in place of the vanilla one, while a moon, a night event or a dimension calls for it. Players can turn fractal skies and the melt effect off in config/fundamentum-sky-client.toml.

File: data/<ns>/fundamentum/fractal_skies/<name>.json. At least one of moon, event and dimension must be given, and all that are given must match. Everything else is optional.

Field	Default	Meaning
`moon`		while this moon is up
`event`		while this night event runs
`dimension`		in this dimension (alone: always there)
`priority`	0	the highest of the skies that match is drawn
`fractal`	`mandelbrot`	`mandelbrot`, `julia` or `burning_ship`
`iterations`	160	16 to 500
`palette`	`rainbow`	`rainbow`, `fire`, `ice`, `acid`, `neon` or `void`
`tint`	`#FFFFFF`	multiplies the colours
`mapping`	`zenith`	`zenith` (centred overhead) or `axes` (seen along each axis and blended, with no seams)
`center`	`[-0.7436, 0.1318]`	where the zoom heads
`scale`	2.5	how much of the plane the sky spans at its widest
`zoom.speed` / `zoom.depth`	0.01 / 4	zoom cycles per second, and how deep
`tour`	false	Mandelbrot only: the whole set spans the sky and each zoom dives into a different spot, then back out
`palette_speed` / `morph_speed` / `rotation_speed`	0.02 / 0.005 / 0.002	cycles per second
`brightness`	0.8
`horizon`	0.25	elevation where the sky is fully shown; it fades out below
`fade_seconds`	4	in and out
`melt`	0	0 to 1: the melting-vision effect over the world while it shows (the client config scales it)

To preview a sky without waiting for its moon, use the client command /fundamentum_sky preview <id>, and /fundamentum_sky off to stop.
