**Unreal Engine** is a high-performance, real-time 3D creation tool developed by Epic Games. Originally created in 1998 for the first-person shooter game *Unreal*, it has evolved into the primary engine behind AAA video games, film/virtual production, architectural visualization, automotive design, and real-time simulation.
---
### Core Pillars & Capabilities
* **Modern Rendering (UE5):**
* **Nanite:** Virtualized geometry system that allows the direct import of film-quality source art (millions of polygons) without manual LOD authoring.
* **Lumen:** Dynamic global illumination and reflections that instantly react to scene and lighting changes without pre-baked lightmaps.
* **Virtual Shadow Maps (VSM):** High-resolution, cinematic contact shadowing.
* **Logic & Visual Scripting:**
* **Blueprints:** A node-based visual scripting system that enables game logic, prototyping, and complex scene automation without writing C++.
* **C++ Backend:** Full native source-code access for performance-critical systems, engine extensions, and low-level optimization.
* **Cinematics & Linear Content:**
* **Sequencer:** A multi-track non-linear editor for cinematic camera animation, shot composition, and audio synchronization.
* **Movie Render Queue (MRQ):** High-end offline rendering pipeline with temporal anti-aliasing, render passes (cryptomatte, depth, normals), and EXR support.
* **World Building:**
* **World Partition:** Grid-based data streaming that replaces manual level streaming, allowing large open worlds to load dynamically based on player or camera distance.
* **PCG (Procedural Content Generation):** Node-based procedural scattering and biome layout tools built directly into the engine.

![Nuke 15 – Node Editing and Cloning Tips
Welcome back! As **Nuke Master**, here is the simple, step-by-step breakdown of the second module image (**Session Topic: Understanding Nodes**) and how every tool, option, and workflow operates inside **Foundry Nuke 15**.
### Step-by-Step Breakdown of Session Contents in Nuke 15
#### 1. Working with Nodes
In Nuke, **Nodes** are the building blocks of every compositing script. Instead of layers, each node performs a specific task (e.g., reading a file, color grading, or keying) and passes visual data down the pipe.
* **Adding Nodes:** Press `Tab` in the Node Graph (DAG) and type the node name, or click tools from the Left Toolbar.
* **Connecting Pipes:** Drag the arrow inputs (like `A`, `B`, `mask`) onto other nodes. In Nuke 15, `B` is always the background/main stream, and `A` is the foreground/overlay stream.
* **Bypassing/Disabling:** Press `D` on your keyboard to disable or re-enable any node quickly without disconnecting it.
#### 2. Selecting Nodes
Navigating your script efficiently requires quick node selection shortcuts:
* **Single Selection:** Left-click (`LMB`) on any node.
* **Multi-Selection:** Drag a marquee box around nodes, or hold `Shift` + click individual nodes.
* **Select Connected Tree:** Click a node and press `Ctrl/Cmd + Alt + A` to select all connected upstream and downstream nodes.
* **Select Upstream Stream:** Hold `Ctrl/Cmd` and drag a node to grab all nodes feeding into it.
* **Search Node by Name:** Press `/` (forward slash) or `Ctrl/Cmd + F` to open the search bar and find specific nodes by name across complex scripts.
#### 3. Renaming Nodes
Keeping the Node Graph structured and readable is essential for pipeline production:
* **Properties Method:** Double-click a node to open its **Properties Panel**, click the top header field (where the node name sits), type the new label, and press `Enter`.
* **Node Labels:** In the properties panel, you can also use the `label` parameter to add helpful text directly underneath the node box in the Node Graph (e.g., adding `[value size]` to show blur radius).
* **Backdrop Node:** Select nodes and press `Alt + N` to wrap them inside a color-coded backdrop box for visual organization.
#### 4. Editing Nodes
Modifying node properties and behaviors:
* **Tweak Parameters:** Adjust numerical values, sliders, wheel controls, or checkboxes inside the Properties Panel.
* **Resetting Values:** Click the small `Ctrl` / reset arrow icon next to a parameter to restore its default value.
* **Replacing Nodes:** Select an existing node, hold `Ctrl/Cmd`, and create a new node (via Tab or Toolbar)—the new node automatically replaces the old one inline.
* **Extracting Nodes:** Select a node inline and press `Ctrl/Cmd + Shift + X` to pull it out of the pipe without breaking the main connection.
#### 5. Cloning Nodes
Cloning creates a live-linked copy of a node. Any parameter change made in the parent node instantly updates all cloned copies.
* **Create Clone:** Select a node and press `Alt + K` (or select `Edit - Clone` from the top menu).
* **Copy as Clone:** Select a node and press `Ctrl/Cmd + K` to copy it, then paste (`Ctrl/Cmd + V`) anywhere else in your script.
* **Visual Indicator:** Cloned nodes in Nuke 15 display a distinct orange connection line linking them together and feature a `C` indicator on the node block.
* **Decloning:** Select a cloned node and press `Alt + Shift + K` to un-link it into an independent node.
#### 6. Roto-scoping
**Rotoscoping (Roto)** is the process of manually creating masks/shapes around elements in a frame to isolate them from their background across time.
* **Keyframes:** Roto shapes use Bézier or B-Spline handles animated over keyframes on the timeline.
* **Sub-frame Motion Blur:** Nuke 15 allows real-time motion blur calculations directly inside the Roto tool using the `Motion Blur` parameter slider.
* **Feathering:** Adjust inner or outer feather handles (`Shift + Drag` points) to create smooth alpha blending on edges.
#### 7. Roto Node
The **Roto Node** (Keyboard Shortcut: `O`) is the dedicated node for vector masking in Nuke:
* **Shape Tools:** Includes **Bézier**, **B-Spline**, **Ellipse**, and **Rectangle** vector toolsets in the Viewer overlay.
* **Layer/Shape List:** The Properties Panel contains a hierarchical folder list where shapes can be grouped, renamed, locked, or hidden.
* **Output Modes:** Channels can be set to write directly to `Alpha`, `RGBA`, or custom user-defined channels.
* **Blending Operations:** Each shape layer offers individual boolean operations like `Over`, `Minus`, `Plus`, `Multiply`, or `Difference` to cut out complex organic forms.
