Create realistic or stylized skies with Skyloom for Unity 6 URP: three-layer volumetric clouds, rain, snow, lightning, dynamic weather transitions, and day and night cycles. All inside one tool!Skyloom – Clouds & Weather is a highly customizable cloud and weather system for Unity 6 URP, designed to bring dynamic skies and atmospheric effects to your projects.Whether you're developing a realistic open-world environment, a stylized fantasy adventure, or an atmospheric indie game, Skyloom provides the tools to create weather conditions that match your artistic vision. Its flexible configuration makes it suitable for virtually any game genre or visual style.Create Your Perfect SkyDesign detailed volumetric skies using three independent cloud layers, each with customizable shapes, density, coverage, altitude, and wind behavior. Choose from 10 cloud formation templates, including Cumulus, Stratus, Cirrus, and Cumulonimbus, or fine-tune individual parameters to create your own unique cloud formations.Adjust cloud lighting, atmospheric haze, scattering, and optional ground shadows to achieve anything from bright, peaceful skies to dramatic storm clouds.Bring Weather to LifeGo beyond static skies with dynamic rain, snow, and thunderstorms. Rainfall can generate expanding surface ripples, splashes, and puddles, while snowfall creates temporary snow patches that gradually melt away.Procedural lightning features customizable branching bolts, synchronized flashes, cloud illumination, and optional distance-based thunder audio using your own sound clips.Dynamic Weather and Day/Night CyclesCreate immersive weather scenarios with customizable weather profiles and smooth transitions between different conditions. Use fixed weather settings for complete artistic control or configure automatic weather scheduling with adjustable durations, transition times, and probabilities.An optional day/night system controls sunlight, ambient lighting, atmospheric colors, and fog throughout the day.Designed for Customization and Workflow EfficiencySkyloom includes a dedicated Unity Editor window that brings its configuration options into one interface. Create and edit weather profiles, apply cloud and weather settings independently, preview transitions, search parameters, and validate your project setup.With 191 different parameters, adjustable rendering quality, and a scripting API for gameplay integration, Skyloom offers extensive control over the appearance and behavior of your environment.From clear summer skies to intense thunderstorms, Skyloom helps you build atmospheric worlds tailored to your project's needs.Key FeaturesThree independent volumetric cloud layers with customizable altitude, thickness, density, coverage, and wind.10 cloud formation templates, including Stratus, Cumulus, Cirrus, Altocumulus, Nimbostratus, and Cumulonimbus.Extensive procedural cloud shaping with erosion, billowing, wisps, towers, anvils, and optional custom weather maps.Customizable cloud lighting, atmospheric scattering, haze, silver linings, and optional screen-space ground shadows.Dynamic rain and snow particle effects with adjustable intensity, appearance, speed, and wind influence.Collision-based rain impacts with surface ripples, splash particles, and dynamically generated puddles.Snow surface patches with configurable accumulation appearance, retention, and melting duration.Procedural lightning with branching bolts, adjustable geometry, animated growth, flashes, and cloud illumination.Optional distance-based thunder playback with support for custom audio clips (audio recordings not included).Customizable weather profiles with built-in templates and smooth runtime transitions.Automatic weather scheduling with weighted probabilities, configurable durations, and transition settings.Optional day/night cycle with customizable sun movement, lighting curves, color gradients, and fog.Dedicated Skyloom Editor window for setup, profile management, parameter search, previews, and validation.191 documented configuration fields for extensive customization.Adjustable rendering quality, including ray-marching steps, lighting samples, and resolution scaling.C# scripting API and Unity events for gameplay integration and runtime weather control.Included HTML documentation with setup instructions, troubleshooting, API examples, and parameter references.Technical Requirements and CompatibilityUnity Version: Unity 6Renderer: Universal Renderer with Render Graph enabledColor Space: LinearGraphics Requirements: Shader Model 4.5 and 3D texture supportTarget Platform: Desktop-class graphics hardwareNot Supported: Built-in Render Pipeline, HDRP, URP 2D Renderer, Render Graph Compatibility Mode, and XR/stereo renderingAdditional Notes: Compatibility with later URP versions and individual target graphics APIs should be validated within the target project.Generative AI tools were used to assist in the development of Skyloom, including the implementation of its code and the creation of its documentation.All AI-assisted content was personally reviewed, refined, and tested by me before being included in the final package. The overall design decisions, feature integration, validation, and final quality control were carried out under my supervision and responsibility.
