| Keyword | Definition |
|---|---|
| Alignment | The alignment is how a brush will be oriented toward the 3D mesh when painting. |
| Alpha | An alpha is a mask that can be used to paint details or complex shapes, for example a bar-code or a logo. |
| Bake | A bake (or baking) refer to the action of computing information from a 3D mesh and saving it into a Texture based on the UV information of a mesh. |
| Bit Depth | The bit depth is the amount of information that can be stored in a texture (per color). The higher the number, the better the precision of the information. However performance decrease with high numbers when doing computations. |
| Brush | A brush is a tool to paint on a mesh. A brush is defined by multiple parameters that control its behavior (such as the size and the opacity). |
| Camera | The camera is the object that allow to control the position and the direction of where you look at in a 3D or 2D viewport. |
| Channel | A channel is a texture with a specific behavior. Some channels are used to define the color of a material, some other channel are used to control the behavior light over a surface. |
| Clone | The clone is a tool used to replicate part of the painting/texture at other location. |
| Content / Mask | The content and the mask refer to the two main properties of a layer. The content is the actual painting stored in the channels that are contained in a layer, while the mask is used to display/hide the content. A black mask is equal to an invisible content. |
| Diffusion | The diffusion is a way or generating information outside the UV island of a mesh. It works by bleeding the last pixels near the border of an UV island, creating blurred colors. |
| Dilation / Padding | On the same idea as the diffusion, the dilation is a way of generating information outside UV island by extending pixels colors. |
| Effect | An effect is an element that can be added on a layer, either on the content or the mask. Substance 3D Painter support various type of effects such as filters. |
| Environment | An environment is an image that is used to compute the lighting of a scene, it is a usually an HDR texture that represent a wide range of color information. |
| Export | The action of exporting is the way of generating flattened textures from the painting realized inside the application. The textures created from the export can be used in other application. |
| FOV / Field of View | The FOV is the extent of the observable world by the Camera. |
| Fill | The Fill is an action (which can be an effect or a layer) that can load a color, a texture or even a material over the whole 3D Mesh. |

| Jitter | The jitter is a property of the brush to produce random behavior when painting. |
| Layer | A layer is an element that contains multiple channels with additional property such as a blending mode and an opacity. |
| Layer stack | A layer stack is a place where layers can be managed and organized. Layers are organized from bottom to top. The bottom layer will be drawn first and then each layer above will be added one by one on top of eahc other. |
| Lazy Mouse | The lazy mouse is a behavior of the brush tool. It slow down the brush path to enhance the precision when painting, created a delay/offset between the mouse cursor and the actual painting. |
| Level | A level is an effect that allow to control a range or color/grayscale information via an histogram. It can be used to invert color or darken/brighten color for example. |
| Log | A log is a text file where are wrote information from the software, usually related to the computer running the application. |

| OpenGL / DirectX | OpenGL and DirectX are both an application programming interface (API) used for rendering 2D and 3D information. They also define the normal map format. |
| Orthographic | An Orthographic projection is a means of representing three-dimensional objects in two dimensions in which all the projection lines are orthogonal to the projection plane. |
| PBR / PBS | Physically based Rendering (PBR) or Physically Based Shading (PBS) is a model in computer graphics that seeks to render graphics in a way that more accurately models the flow of light in the real world. |
| Packing | Packing is the action of storing multiple images inside one texture. Because textures are composed of separated Red, Green, and Blue channels, they can store different information which can be read independently in an other application. |
| Particles | Particles are a kind of tool that generate brush strokes based on physical properties or other complex behaviors. |
| Perspective | Perspective is an approximate representation or a object or scene seen by the human eye on a flat surface (like a screen). It’s a simulation of depth and scale. |
