1. Development & Ecosystem Web & Mobile Website: A collection of HTML/CSS/JS pages hosted on a server. The Frontend handles the visual aspect, while the Backend manages data (databases, servers).

Mobile App: Software designed for smartphones. It is either Native (Swift for iOS, Kotlin for Android) for performance, or Cross-platform (React Native, Flutter) to use a single codebase for both systems.

Unreal Engine 5 (UE5) UE5 is the most powerful engine for real-time rendering.

Blueprints: A node-based visual scripting system (allows for logic creation without writing C++).

Nanite: A virtualized geometry system that allows the import of millions of polygons without performance lag.

Lumen: A dynamic global illumination system where light reacts in real-time to environmental changes.

2. 3D Creation in Blender The workflow generally follows this order:

Modeling The act of sculpting or building the structure of an object.

Low Poly: Low polygon count, ideal for mobile games.

High Poly: Extreme detail, used for cinema or to "bake" details onto a simpler model.

UV Unwrapping The most critical step for texturing.

Principle: "Cutting" the 3D object to flatten it into 2D (similar to a sewing pattern).

Importance: Poor unwrapping leads to stretched or distorted textures on the object.

Shading / Texturing The application of materials (metal, glass, skin).

PBR (Physically Based Rendering): The standard method that simulates how light realistically reacts to surfaces.

Texture Nodes: In Blender, you connect blocks (color, roughness, relief/normal maps) to create a realistic render.
