Baiyu Milky Way Skybox

Introduction

This is a Milky Way space skybox based on the FabricSkyboxes mod. The resource was converted from the Scientific Sky Simulator and currently only provides a night starfield sky effect. Skyboxes for sunrise or rainy weather are not included at this time.

Dependencies

Need Nuit (formerly FabricSkyboxes) : nuit in modrinth

Quick Start

1.1 Install Nuit

1.2 Download resource

Download the latest resource, place it in the folder \resourcepacks\

Advanced

2.1 Extract

Extract \resourcepacks\Baiyu Milky Way Skybox.zip to \resourcepacks\Baiyu Milky Way Skybox\. Open the folder \resourcepacks\Baiyu Milky Way Skybox\assets\nuit\sky\ ，edit sky6_starfield.json.

2.2 simplest, during the Winter Solstice

In fact, I do not know whether this specifically refers to the Winter Solstice or January 1st.

"mapping": {
    "0": [latitude, 0.0, 0.0]
},
"axis": {
    "0": [-90 + latitude, 0.0, 0.0]
}

latitude: your located latitude. Positive for North, negative for South (e.g., 22.54 for 22.54°N, -33.87 for 33.87°S).
Leave the other two numbers (0.0) unchanged.

2.2.1 Example Shenzhen (approx. 22.54°N)

Latitude = 22.54
mapping: [22.54, 0.0, 0]
axis: -90 + 22.54 = -67.46, so use [-67.46, 0.0, 0]

"mapping": {
    "0": [22.54, 0.0, 0]
},
"axis": {
    "0": [-67.46, 0.0, 0]
}

2.2.1 Example Sydney (approx. 33.87°S)

Latitude = -33.87 (remember the minus sign for South)
mapping: [-33.87, 0.0, 0]
axis: -90 + (-33.87) = -123.87, so use [-123.87, 0.0, 0]

"mapping": {
    "0": [-33.87, 0.0, 0]
},
"axis": {
    "0": [-123.87, 0.0, 0]
}

2.3 during the Summer Solstice

This configuration sets the initial sky to the Summer Solstice (around June 21). The second number in mapping is fixed at 180.0 to represent the half‑year phase shift.

"mapping": {
    "0": [180 - latitude, 180.0, 0.0]
},
"axis": {
    "0": [-90 + latitude, 0.0, 0.0]
}

• latitude: your located latitude. Positive for North, negative for South.
• Leave the other two numbers (0.0) unchanged.

2.3.1 Example Shenzhen (approx. 22.54°N)

Latitude = 22.54
mapping: [180 - 22.54 = 157.46, 180.0, 0]
axis: -90 + 22.54 = -67.46, so use [-67.46, 0.0, 0]

"mapping": {
    "0": [157.46, 180.0, 0]
},
"axis": {
    "0": [-67.46, 0.0, 0]
}

2.3.2 Example Sydney (approx. 33.87°S)

Latitude = -33.87 (remember the minus sign for South)
mapping: [180 - (-33.87) = 213.87, 180.0, 0]
axis: -90 + (-33.87) = -123.87, so use [-123.87, 0.0, 0]

"mapping": {
    "0": [213.87, 180.0, 0]
},
"axis": {
    "0": [-123.87, 0.0, 0]
}

2.4 On any day of the year

idk.I've been deriving it for several days, but I still don't know how to tackle it. The mapping is really strange; x, y, and z seem to be coupled.But the celestial sphere rotates a bit more each day, so you can wait for the in-game time to pass, and the celestial sphere will also change at the same fixed time each day accordingly.
