The white and red icon which defaults at the center of the scene. The 3D Cursor is used as a reference point for many operations in the 3D viewport.
The main visual editor in Blender where the 3D scene can be viewed.
A third-party extension which can be installed in Blender to extend functionality or simplify a function. Find the best Blender Add-Ons here.
A greyscale image used as an input to an alpha socket in a node. Purely black areas of the image will be purely transparent. Pure white areas will not be transparent at all. Grey areas will be translucent based on how dark or light they are.
A Blender modifier which creates instanced copies of the object and then arranges them according to settings established by a user in the modifier properties panel.
A feature introduced in Blender 3.0 to organize and quickly import objects, materials, collections and more. A full guide on the Asset browser can be found here.
The shape of a bevel as seen from its side. These default to “Superellipse” but can be customized.
A Creative Commons license which allows full use of an asset (personal or commercial) without requiring attribution to the creator.
A node-based editor in Blender which allows for image post-processing after a rendered image is complete. We can non-destructively adjust the look of a rendered image using this editor.
Blender’s built-in ray-tracing render engine. A very realistic render engine, but demanding on memory.
A modifier in Blender which reduces the geometry of a mesh while striving to maintain the object’s shape. It’s a great tool to significantly reduce the face count of an object and make it more efficient.
A rendering process to reduce noise and firefly artifacts in the final render.  Blurring the image is often a side-effect. Blender has a series of denoising options that can be accessed in the Render Properties or in the Compositor.
Mode in Blender to edit an individual object. Pressing “Tab” toggles between Edit Mode and Object Mode in the 3D Viewport.
Blender’s built-in real time render engine. It is faster than Cycles but at the cost of realism.
An object type in Blender which is not rendered. These commonly serve as reference points and parent objects.
Term to describe a data block (such as an object or material) with no current users, but which has been marked as “fake” so it is not purged when Blender closes. We mark data blocks as “Fake Users” when we don’t have them actively assigned but want to save them in the .Blend file for...
The grid that is visible at zero on the Z axis in the 3D viewport. It is used for reference of distance and height in a scene. Its visibility can be toggled off in the Overlay Settings.
High Dynamic Range Images: Images with high range of color depth can be used as background images and can provide lighting to a scene. These images are formatted to replace the “world” and wrap 360 degrees around a scene.
A light with strength, output and shape characteristics provided by an IES file. IES files are standardized data files which can simulate real world lights by various manufacturers. IES stands for Illuminating Engineering Society.
Index of Refraction (IOR) In physics, is a measurement of how much light bends when it passes from one medium to another. In Blender, this can be simulated when working with glass or translucent material shaders.
A copy of an object which does not use its own data. It uses the data of the original object it is copying. Instancing saves memory and data.
A process in computer animation that calculates the change in an object from one key frame to another. Rather than manually calculating the value for each frame, the computer “interpolates” it. Blender has different methods of interpolation (linear, bezier, constant, etc).
Designated frames where a value (location, scale, rotation or other) is set. A second key frame can be set with a different value and the value will change over the frames between the key frames.
A term for the list of modifiers in the modifier properties panel. The modifiers take effect in order from top to bottom of the “stack.”
An add-on which comes installed with Blender. It extends the functionality of nodes within Blender and adds numerous shortcuts for node management.
Every face and vertex in 3D software faces a direction. This direction is called the “normal” and it is used to determine how light interacts with the geometry. Normals can be manipulated to change the lighting effect.
Mode in which Objects can be moved and arranged in a scene, but individual objects can not be edited. Use “Tab” while in the 3D Viewport to toggle between Edit Mode and Object Mode.
An options panel which appears in the bottom left corner of the 3D viewport after certain operations. Once we move to the next operation, these options are no longer available.
An editor in Blender for organizing objects and collections. It acts as a folder system to organize a scene.
A powerful shader in Blender used as the default for new materials. It has many settings to simulate real-world materials.
An editor in Blender which displays property settings. Many settings are dependent on the selected object. Properties tabs include: Tool, Render, Output, Layer, Scene, World, Collection, Object, Modifiers, Particles, Physics, Constraints, Data, Materials, Textures (and more depending on the object type).
A method of editing elements of a mesh, curve or even objects themselves. When an element is moved, the surrounding elements are moved with it and proportionally. The falloff can be adjusted for different effects.
A grey scale image texture which defines the roughness for a PBR material. Roughness refers to how smooth the surface of a material is.
A mode in Blender designed specifically for sculpting meshes.
An editor in Blender for creating materials and editing the world backgrounds with nodes.
An animation feature which allows morphing an object from one shape key to another. They are managed in the Data Properties tab within the Properties Panel.
Menu on the right side of most editors (including 3D viewport) which is toggled open and closed with “N” on the keyboard.
The screen displayed when Blender opens. Contains new and recent file settings as well as helpful links.
Menu at the top of Blender where we find File, Edit, Render, Window and Help options.  
A setting which tells Blender what the pivot point or origin point for certain operations will be. It is used in transformations such as moving, rotating and scaling, but also for operations such as extrude. 
Menu for adjusting preferences, controls and settings. Also where we install and manage add-ons. Found under Edit in the Top Bar.
A drop-down menu located at the top of the 3D Viewport. From the menu, several display options can be toggled on and off, including: grid, floor, extras, 3D cursor, face orientations and normals.   Options available in the overlays menu differ between object and edit mode.
