A visual effect that creates a trail or streak of particles or geometry following the movement of an object. Trails are often used to depict fast motion, projectiles, or lingering effects.

A grayscale texture or mask used to define the transparency or alpha values of a corresponding color texture or image. Transparency masks allow for precise control over which areas of an asset are transparent or opaque.

A grayscale image or texture used to define threshold values for various effects, such as alpha masking, blending, or transitions. Threshold maps determine which areas are affected by specific operations based on their grayscale values.

The precise control and synchronization of visual effects, animations, and gameplay events. Timing is crucial for creating smooth and responsive experiences in games.

The specific hardware or platform for which a game or project is developed and optimized. Target platforms can include consoles, PCs, mobile devices, or virtual reality platforms.

A technique where multiple smaller textures are combined into a larger texture sheet to reduce draw calls and improve performance. Texture atlases are commonly used for optimizing the rendering of objects with multiple materials or textures.

A vector that defines the orientation or direction of a surface or mesh. Tangents are used in shading calculations, normal mapping, and other operations that require surface orientation information.


The graphical elements and controls displayed on the screen that allow players to interact with the game. UI can include menus, buttons, HUD (Heads-Up Display), and other visual elements.

The process of assigning 2D texture coordinates to the vertices of a 3D mesh in VFX. UV mapping enables the mapping of textures and materials onto the surface of 3D objects accurately.

A shader or material that doesn’t consider lighting calculations and displays colors or textures without any influence from light sources. Unlit materials are often used for UI elements, special effects, or specific art styles.

A popular game engine developed by Epic Games that provides a suite of tools and features for creating interactive experiences. Unreal Engine offers a visual scripting system, advanced rendering capabilities, and extensive content creation tools.

The process of refreshing or modifying the state of objects, variables, or parameters. Updates can include changes to particle positions, animation states, material properties, or any other dynamic aspect of the game world.

The process of increasing the resolution or quality of an image, texture, or frame. Upsampling is often used to enhance visual fidelity, reduce aliasing, or improve the level of detail in rendered images.

The distortion or stretching of UV coordinates, typically caused by non-uniform scaling, deformation, or complex geometry. UV distortion can affect the appearance and mapping accuracy of textures on 3D objects.

Another popular game engine widely used in the industry for creating games and interactive experiences. Unity provides a comprehensive set of tools and features for VFX creation, including a visual scripting system, physics simulation, and asset management.

The 2D coordinates assigned to each vertex of a 3D mesh that determine how textures are mapped onto the surface. UV coordinates provide the mapping information required to accurately apply textures and materials to objects.

The process of creating a 2D representation of a 3D mesh by flattening its surfaces onto a 2D plane. UV unwrapping allows for precise texture mapping by providing a visual template for texturing artists

The input, opinions, and observations provided by players or users of a game. User feedback is valuable for improving the gameplay experience, identifying issues, and refining elements based on player preferences.

The creation of user interface (UI) and user experience (UX) elements in a game.


The creation and implementation of visual elements in games to enhance the player’s experience. VFX includes various effects such as explosions, fire, smoke, water, particle systems, lighting effects, and more.

A proprietary shading and scripting language used in Houdini, a popular 3D animation and VFX software. VEX allows for complex procedural effects, custom shader creation, and efficient computation in pipelines.

A point in 3D space that defines the position of a corner or intersection of geometric shapes or polygons. Vertices collectively form the geometry of objects and are used for calculations like shading, deformation, and animation.

A mathematical representation of a magnitude and direction. Vectors are commonly used to describe positions, movements, forces, velocities, and other physical quantities in games.

A 3D region or space that represents a quantity or property, such as density, fog, or particle distribution. Volumetric effects are used to create atmospheric and immersive visuals, including volumetric lighting and clouds.

The graphical display area in a game engine or 3D software where artists and developers can view and manipulate the scene or assets. The viewport provides real-time feedback on the changes made to objects, materials, and VFX.

A technique where the position, orientation, or other attributes of individual vertices are animated to create dynamic and deformable surfaces without relying on skeletal animation. Vertex animation can be used for cloth simulation, fluid effects, or organic deformations.

The property of an object, particle, or effect being visible or invisible in the game world. Visibility can be controlled based on factors such as distance, occlusion, alpha values, or custom conditions.

A virtual representation of a camera in a game engine used to define the perspective and view of the player or the in-game cinematic sequences. Virtual cameras allow for controlling the framing, movement, and other parameters of the camera.

The speed and direction of an object’s motion. Velocity is often used to calculate the movement of particles, simulate physical forces, determine collision responses, or create realistic motion blur effects.

A visual effect applied to the edges or corners of the screen  that darkens or fades the image. Vignettes are commonly used to enhance focus, draw attention, or evoke a specific mood or style.


A method of creating gameplay mechanics, logic, using a visual interface or node-based system instead of traditional programming. Visual scripting allows artists and designers to create interactive experiences without extensive coding knowledge.
