Cinematic split-screen interaction system for Unity with smooth camera transitions, multiple layouts, interaction prompts, control locking, and optimized rendering.Compatible with Built-in Render Pipeline and URP. Uses standard Unity cameras, UI, and scripting workflows without relying on pipeline-specific shaders. For best performance and visual stability, use dedicated culling layers for interaction cameras and avoid heavy post-processing effects such as TAA or Motion Blur. HDRP compatibility is not officially tested in this version.Cinematic Split Interaction System is a complete interaction framework built for Unity that helps developers create immersive split-screen gameplay moments with cinematic presentation and smooth transitions.The system activates when the player interacts with a gameplay object, such as a vault terminal, puzzle machine, control panel, or security system. Once activated, the screen smoothly transitions into multiple camera views, allowing the player to simultaneously observe both the interaction itself and the result of that interaction.For example:A player enters a vault roomPresses E to interact with a keypadThe player camera smoothly moves to a cinematic close-up of the keypadA secondary camera displays the vault door reacting in real timeThe screen splits dynamically to show both perspectives togetherThe framework includes multiple display modes:Side-by-side split screenTop-bottom split screenPicture-in-picture modeAll layouts are customizable directly through the inspector.The system is built with usability and performance in mind:Secondary cameras activate only during interactionsLayer-based rendering reduces unnecessary rendering costLightweight UI keeps runtime overhead lowStable viewport transition logic minimizes rendering artifactsAdditional features include:Smooth camera blendingInteraction promptsPlayer movement locking during interactionEscape-to-exit supportCinematic camera target framingInspector-driven workflow for quick setupThe package is modular and reusable, making it suitable for many gameplay scenarios including:Puzzle mechanicsSecurity systemsCCTV monitorsHacking terminalsReactor controlsSci-fi interfacesObservation gameplayHorror interaction systemsWhether used in indie projects, technical art workflows, gameplay prototypes, or production-ready mechanics, the Cinematic Split Interaction System provides an easy and scalable way to create cinematic gameplay interactions inside Unity.
