Texture Editor

The Texture Editor allows painting textures of the materials applied to objects directly in the scene. It is mainly used for painting masks, but also helps editing the existing textures: adding some details or fixing mistakes.

The Texture Editor is available when the Texture Paint Mode is selected on the toolbar:

The Active Tool window provides access to the tools of the Texture Editor:

To edit a texture via the Texture Editor, do the following:

1. Select an object, a texture of which should be edited.
2. In the Texture field of the Texture Editor, choose the required texture from the drop-down list.

   

3. Paint directly on the object using the available tools.
   Notice

   When painting, the original asset is edited.

To undo all changes, select another object in the scene and decline saving changes in the window that opens:

Saving Changes#

The following tools are available:

• Brush tool (B hotkey) allows painting arbitrary shapes on the texture.
• Pencil tool allows painting hard-edged texels on the texture.
• Eraser tool (E hotkey) removes changes.
• Smooth tool (V hotkey) blurs texels of the texture.
• Smudge tool smudges the texture.
• Contrast tool changes the texture contrast.
• Brightness tool changes the texture brightness.
• Saturation tool changes intesity of the texture colors.
• Replace Color tool replaces all texture colors with the specified one.
• Invert tool inverts texture colors.
• Draw Flowmap tool allows painting a flow map.
• Draw Mesh Data tool allows drawing textures that store mesh data (positions, mesh normals).
• Ambient Occlusion tool allows drawing an ambient occlusion texture.
• Curvature tool allows painting a curvature texture.
• Leaks tool allows painting leaks.
• Color Picker tool allows picking a texture color.

Depending on the selected tool, a set of available settings varies. However, there are settings common for most of the tools:

Texture	Texture to be edited.
Show Debug	Show per-channel changes.
Stroke Mode	— draw a stroke of brush marks. — draw a sigle brush mark. — fill the selected rectangular area with a specified color. By default, areas of the object that are visible in the current viewport are filled. — draw a linear gradient. — draw a line. It can be used, for example, to align edges of a mask. — fill the texture with a specified color. Notice The set of tool settings changes depending on the Stroke Mode. See the Stroke Modes Specific Settings chapter for details.
Rotate Along Stroke	Orients the brush marks to follow the stoke direction. Rotate Along Stroke Disabled Rotate Along Stroke Enabled
Brush Texture	Texture that defines shape of the brush.
Brush Texture Opacity	1-channeled opacity texture that controls application of the Brush Texture. White areas of the texture make the corresponding areas of the Brush Texture fully visible, black ones make them fully transparent.
Brush Radius	Radius of the brush. Notice You can change the brush radius by scrolling the mouse wheel. Brush Radius = 0.03 Brush Radius = 0.01
Brush Spacing	Distance between the brush marks in the stroke, in percent. 0 means the brush mark is drawn each frame (i.e. no spaces). Brush Spacing = 0 Brush Spacing = 100
Brush Angle	Angle of the brush marks, in degrees. Brush Angle = 0 Brush Angle = 30 Brush Angle = 60
Opacity	Strength of the brush. Higher values create more opaque bush strokes. Multiple applications of the brush with low opacity to the same place create a more opaque image. It can be used for drawing smooth gradients. Opacity = 0.3 Opacity = 0.3, multiple brush applcations Opacity = 1.0
Color	Color of the brush. You can specify the Main and the Spare color and switch them by pressing X when painting the texture. To pick a texture color, press C or click the Pick Screen Color button in the Select Color window and sample the color.
Color Intensity	Intensity of the brush color. It allows changing shades of the same color: the lower the value, the darker the result. Color Intensity = 1.0 Color Intensity = 0.5 Color Intensity = 0.1
Brush Backface Culling Angle	Normal angle at which the surface is ignored by the brush. It allows you to avoid painting across certain surfaces. Culling Angle = 90 Culling Angle = 120
Radius Jitter	Random radius of the brush marks in the stroke. 0 means no randomness.
Angle Jitter	Random rotation angle of the brush marks in the stroke (in dergees). 0 means no randomness.
Position Jitter	Random position offset of the brush marks in the stroke (in units). 0 means no randomness.
Procedural Mask	Limits brush application to a certain area: Normal — paint without restrictions. Dark Area of Ambient Occlusion — paint only dark areas of ambient occlusion. When this option is used, settings of the ambient occlusion are available. Light Area of Ambient Occlusion — paint only light areas of ambient occlusion. When this option is used, settings of the ambient occlusion are available. Ambient Occlusion Dark Area of Ambient Occlusion Light Area of Ambient Occlusion Cavity — paint only cavity areas. When this option is used, settings of the curvature are available. Convexity — paint only convex areas. When this option is used, settings of the curvature are available. Cavity Convexity Painting the cavity/convex area can be useful when, for example, you need to paint a cavity/convexity mask for a huge building.
Active Channels	Channels that are modified when painting the texture.
UV Channel	UV channel that is modified when painting the texture. UV Channel 0 — 1st UV channel. UV Channel 1 — 2nd UV channel. For example, if the 2nd UV channel stores a mask for blending materials, you will choose UV Channel 1 when editing this mask.

Stroke Modes Specific Settings#

The Rectangle and Linear Gradient stroke modes have additional specific settings described below.

Depth Limit	Depth limit for filling areas of the object that are not visible in the current viewport (i.e. occluded by other objects).
Depth Limit Gradient Length	Size of the gradient along the edges of the filled area.
Rectangle Texture	Texture that fills the selected rectangular area. Available for the Rectangle mode only. Object with Original Texture Rectangular Texture Applied
Rectangle Texture Opacity	1-channeled opacity texture that controls application of the Rectangle Texture. White areas of the texture make the corresponding areas of the Rectangle Texture fully visible, black ones make them fully transparent.
