SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Controlling celestial visuals in Ultra Dynamic Sky involves many scattered settings across Sun, Moon, Stars, Aurora, Sky Glow, and Space Layer categories, and common issues like planets not rendering or stars looking tiled are hard to diagnose without knowing the underlying systems. ## Core Features & Use Cases - Sun and Moon Positioning: Set sun/moon paths via Yaw, Pitch, and Vertical Offset, or disconnect them from time entirely using the Manually Position Sun/Moon Target widgets. - Appearance and Phases: Tune sun disc scale, softness, color, and eclipse behavior; control moon textures and phases, including disabling Render Moon Phases for custom moons. - Stars, Aurora, and Space Layer: Swap tiling stars for a 360 star map, enable 2D or Volumetric Aurora, add night sky glow and light pollution, and place planets, moons, and nebula via DBuffer decal rendering. - Use Case: A user wants a giant alien moon with aurora borealis in a night scene. Disable Render Moon Phases with a custom moon texture, enable Use Auroras with a compatible Sky Mode, and raise Night Sky Glow so the scene stays readable without moonlight. ## Quick Start Ask the agent to position the sun manually with the Sun Target widget and add a visible planet using the Ultra Dynamic Sky Space Layer.

Frequently Asked Questions about ue-uds-sun-moon-stars

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I manually position the sun in Ultra Dynamic Sky?▼

Enable Manually Position Sun Target in the Sun category, then move the blue diamond Sun Target widget in the level viewport. The sun points from the UDS actor toward the widget, and this method overrides both time-based paths and the simulation.

How do I add aurora borealis in Ultra Dynamic Sky?▼

Enable Use Auroras in the Aurora category with a compatible Sky Mode for the 2D shader effect, or set Sky Mode to Volumetric Aurora for full 3D aurora the camera can fly through. Note that Volumetric Aurora disables volumetric clouds.

Why is the Space Layer not rendering planets in Ultra Dynamic Sky?▼

The Space Layer renders via DBuffer mesh decals, so the DBuffer Decals project setting must be enabled on desktop, or Mobile DBuffer Decals on mobile. If planets, moons, or nebula render nothing, this setting is almost always the cause.

Why are my sun position settings ignored in Ultra Dynamic Sky?▼

Sun Yaw, Pitch, and Vertical Offset are ignored when Simulate Real Sun/Moon is enabled, since the simulation overrides manual path settings. Manually Position Sun Target also takes priority over everything else if it is enabled.

Why do stars look pixelated and tiled in Ultra Dynamic Sky?▼

That is the default Tiling Stars texture, a simple repeating pattern. Enable Simulate Real Stars to switch to the 360-degree star map, or swap the Tiling Stars texture for a higher-resolution one.

Why does changing Sun Scale at runtime have no effect?▼

Sun Scale is a static property, so runtime changes do not apply until you call Static Properties - Sun on the UDS actor. For an instant full refresh of all static properties, call Hard Reset Cache.
