Streamline: Universal Scene Streaming & Management

Streamline is the definitive solution for developers seeking AAA-grade scene management in Unity. Say goodbye to "Magic Strings" and CPU spikes during level loads. This system transforms scene handling into a robust Data-Driven workflow, optimized for peak performance and enterprise-level scalability.

Whether you are building a simple mobile game or a massive open world divided into "chunks," Streamline provides the tools necessary to deliver fluid transitions and an uninterrupted user experience.

Core: Data-Driven Architecture

The heart of Streamline lies in its SceneProfiles. Every scene is defined as a ScriptableObject, allowing you to visually configure loading behavior, background music, and specific transition effects, completely decoupling configuration from your code.

Open World Streaming & LRU Caching

Streamline features an advanced streaming engine designed for seamless world segments or "Chunks."

• Zero-Allocation Scene Caching: Powered by a Least Recently Used (LRU) memory algorithm. When a chunk is unloaded, the system keeps it hidden in RAM rather than destroying it. This allows for instant, 1-frame reloads if the player returns, eliminating loading times entirely.
• Intelligent Stream Zones: Implement streaming based on player distance (with visual hysteresis to prevent loading flickers), physical triggers, or narrative-driven events.

Advanced Portal System (Entry Points)

Moving players between scenes with pinpoint precision has never been easier. Using the global ID database, you can utilize ScenePortals to teleport players to specific coordinates in a target scene via SceneEntryPoints upon arrival.

Visual Excellence & UX

• AAA Transition Engine: Includes a library of professional shaders such as Grid Shatter, Whirlpool, Iris, Dissolve, Blinds, and Double Wipe.
• Universal Pipeline: Native support for both Built-in and URP (via Scriptable Renderer Features).
• Dynamic Loading Screens: A theme-based system featuring random backgrounds and a "Loading Tips" database to maximize player engagement.

Key Features

• Editor Control Center: A centralized hub (Tools > SceneLoader) to manage profiles, registries, portals, and theme settings without digging through folders.
• Type-Safe Code Generator: Automatically generates a constants script, allowing you to call your scenes from code safely while preventing typos and refactoring errors.
• Async Task Queue: Register custom processes—such as procedural generation or network syncing—that keep the loading screen active until your logic is 100% ready.
• Third-Party Integrations: Out-of-the-box support for Addressables, Unity Timeline (via custom tracks), and DOTween.
• 6 Demo Scenarios: Ready-to-play examples ranging from enterprise sub-scene workflows to full open-world streaming setups.
