Tsukimeguri - Lunar Cycle -

Tsukimeguri - Lunar Cycle - is a dynamic moon gimmick for VRChat avatars and Unity scenes.

It renders a circular moon with pseudo-spherical lighting on a standard Unity Quad. Simply place the included prefab in your scene or under an avatar bone to get started.

IMPORTANT:

This product is intended for the Windows PC version of VRChat.

Quest Standalone / Android VRChat is NOT supported because Tsukimeguri uses a custom shader.

Meta Quest headsets can still use Tsukimeguri when running the PC version of VRChat through PCVR, such as Virtual Desktop, Quest Link, or Air Link.

FEATURES

• Automatic lunar phases with Phase Offset

• New Moon Glow and Full Moon Glow

• Full Moon Aura Wave

• Moon Tint, Normal, Height, and Cavity controls

• Camera-facing Billboard and Ground-Locked Down Direction

• VRChat Network Time synchronization

• Dedicated Moon Shader and Custom Inspector

REQUIREMENTS & SETUP

• Windows PC version of VRChat

• Quest Standalone / Android VRChat is not supported

• Meta Quest + PCVR is supported when using the Windows PC version of VRChat

• Unity 2022.3.22f1 baseline

• No lilToon dependency

Import the included .unitypackage, then place the Tsukimeguri prefab in your scene or under an avatar bone.

The prefab already includes the Unity Quad, Material, and custom Shader, so you do not need to create a Quad manually.

Japanese and English guides (HOWTO_JA.md / HOWTO_EN.md) are included.

PC / QUEST COMPATIBILITY

Tsukimeguri uses the custom shader:

Tsukimeguri/MoonBillboard

Because of this, the product is designed for the Windows PC version of VRChat.

Supported:

• Windows PC VRChat

• Meta Quest + Virtual Desktop

• Meta Quest + Quest Link / Air Link

• Other PCVR setups running the Windows version of VRChat

Not supported:

• VRChat running directly on Meta Quest in Standalone mode

• Android VRChat

NOTES

When Synchronize Phase Timing is ON, the moon may appear paused in Unity Edit Mode because VRChat Network Time may not be available there.

Turn synchronization OFF when previewing the lunar cycle directly in the Unity Editor.

In VRChat, the final appearance of the Glow may vary depending on the world's Bloom and post-processing settings.
