Overview
The plugin allows you to display multiple independent viewports simultaneously:
- inside the main Unreal Engine viewport,
- in standalone OS-level windows,
- as fully customizable split-screen and grid layouts.
MultiViewProjectionTools does NOT use SceneCapture2D.
All rendering is performed directly through Unreal Engine’s native viewport pipeline, providing:
- correct Lumen, Nanite, shadows, and post-processing,
- full Temporal AA / TSR support,
- no additional render targets or capture latency,
- significantly better performance compared to SceneCapture-based solutions.
Core Features
- Multiple independent viewports per camera
- Per-camera rendering without SceneCapture2D
- Standalone viewport windows (separate OS windows)
- Custom layouts: split-screen, multi-window, grid
- Camera or PlayerController-based viewport binding
- Dynamic viewport size and position control
- Works in Editor, PIE, and runtime
- Designed for complex multi-camera workflows
Feature 1: Separate Window Viewports
- Creates standalone viewport windows using Unreal Engine’s native window system (Slate).
- Renders real camera views through the full engine rendering pipeline (no SceneCapture2D).
-
Automatic window lifecycle management:
- windows are created and destroyed automatically.
- Supports multiple independent windows simultaneously.
- Works in both Editor and packaged builds (Runtime).
Feature 2: Widget Viewport (UMG / Slate)
Embeds a real Unreal Engine viewport directly into UMG or Slate UI.
- Uses the native rendering pipeline (post-process, lighting, TAA/TSR supported).
- Supports dynamic resizing, DPI scaling, and aspect-ratio–aware rendering.
- Can render a specific camera or player view.
- Designed for high-performance camera previews and multi-view UI panels.
- Control Main Viewport: allows you to control the position and size of the main viewport.
