纹理编辑器

章节:

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 details or fixing mistakes. Moreover, the Texture Editor allows creating a new surface custom texture and paint it from scratch.纹理编辑器允许直接在场景中绘制应用于对象的材质纹理。它主要用于绘制蒙版，但也有助于编辑现有纹理:添加细节或修复错误。此外，纹理编辑器允许创建一个新的表面自定义纹理并从头开始绘制它。

The Texture Editor is available when the Texture Paint Mode is selected on the toolbar:当在工具栏上选择Texture Paint Mode时，纹理编辑器可用:

注意

您也可以使用Shift+2热键来激活该工具。

The Active Tool window provides access to the tools of the Texture Editor:Active Tool窗口提供了对纹理编辑器工具的访问:

Common Settings常见的设置#

Depending on the selected tool, a set of available settings varies. However, there are settings common for most of the tools:根据所选工具的不同，一组可用的设置会有所不同。然而，大多数工具都有一些共同的设置:

Texture

要编辑的纹理。

Show Debug

显示每个频道的变化。

Stroke Mode

笔画模式:

Brush — draw a stroke of brush marks. Brush：画一笔笔刷标记。
Stamp — draw a sigle brush mark. Stamp：画一个西格勒画笔标记。
Lasso — fill the selected rectangular area with a specified color. By default, areas of the object that are visible in the current viewport are filled. Lasso：用指定的颜色填充选定的矩形区域。默认情况下，填充当前视口中可见的对象区域。
Gradient — draw a linear gradient. Gradient：绘制一个线性梯度。
Line — draw a line. It can be used, for example, to align edges of a mask. Line：画一条线。例如，它可以用来对齐蒙版的边缘。
Fill — fill the texture with a specified color. Fill：用指定的颜色填充纹理。

注意

工具设置集的变化取决于Stroke Mode。具体请参见笔画模式特定设置章节。

Rotate Along Stroke

Orients the brush marks to follow the stroke direction.调整笔刷标记以遵循笔画方向。


Rotate Along Stroke Disabled沿笔画旋转禁用	Rotate Along Stroke Enabled沿笔画旋转启用

Brush Texture

Texture that defines shape of the brush.定义笔刷形状的纹理。

Brush Texture Opacity

1通道不透明度纹理，控制画笔纹理的应用。纹理的白色区域使画笔纹理的相应区域完全可见，黑色区域使它们完全透明。

Brush Radius

Radius of the brush.画笔的半径。

注意

您可以通过滚动鼠标滚轮来更改笔刷半径。


Brush Radius = 0.03刷半径 = 0.03	Brush Radius = 0.01刷半径 = 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).笔画中笔画痕迹之间的距离，以百分数表示。0表示每帧绘制画笔标记(即没有空格)。


Brush Spacing = 0刷距 = 0	Brush Spacing = 100刷距 = 100

Brush Angle

Angle of the brush marks, in degrees.刷痕的角度，以度为单位。


Brush Angle = 0刷角 = 0	Brush Angle = 30刷角 = 30	Brush Angle = 60刷角 = 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.笔触的力度。更高的值会产生更不透明的笔触。在同一位置多次使用低不透明度的笔刷创建一个更不透明的图像。它可以用来绘制平滑的渐变。


Opacity = 0.3不透明度 = 0.3	Opacity = 0.3, multiple brush applcations不透明度 = 0.3，多个笔刷应用	Opacity = 1.0不透明度 = 1.0

Color

画笔的颜色。您可以指定Main和Spare颜色，并在绘制纹理时按X来切换它们。要选择纹理颜色，请按C或单击Select Color窗口中的Pick Screen Color按钮并对颜色进行采样。

Color Intensity

Intensity of the brush color. It allows changing shades of the same color: the lower the value, the darker the result. 笔刷颜色的强度。它允许改变相同颜色的深浅: 值越低，结果越深。


Color Intensity = 1.0色彩强度 = 1.0	Color Intensity = 0.5色彩强度 = 0.5	Color Intensity = 0.1色彩强度 = 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.画笔忽略表面的法线角度。它可以让您避免在某些表面上作画。


Culling Angle = 90剔除角度 = 90	Culling Angle = 120剔除角度 = 120

Radius Jitter

Random radius of the brush marks in the stroke. 0 means no randomness.笔画中画笔痕迹的随机半径。0表示没有随机性。

Angle Jitter

Random rotation angle of the brush marks in the stroke (in degrees). 0 means no randomness.笔画中刷痕的随机旋转角度(以度为单位)。0表示没有随机性。

Position Jitter

Random position offset of the brush marks in the stroke (in units). 0 means no randomness.笔画中笔刷标记的随机位置偏移(单位)。0表示没有随机性。

Procedural Mask

Limits brush application to a certain area:将刷子的使用范围限制在一定范围内;

Normal — paint without restrictions.Normal：不受限制的油漆。
Dark Area of Ambient Occlusion — paint only dark areas of ambient occlusion. When this option is used, settings of the ambient occlusion are available.Dark Area of Ambient Occlusion：仅绘制环境光遮挡的黑暗区域。使用此选项时，环境光遮挡设置可用。
Light Area of Ambient Occlusion — paint only light areas of ambient occlusion. When this option is used, settings of the ambient occlusion are available.Light Area of Ambient Occlusion：仅绘制环境光遮挡的浅色区域。使用此选项时，环境光遮挡设置可用。


Ambient Occlusion环境闭塞	Dark Area of Ambient Occlusion暗区域的环境遮挡	Light Area of Ambient Occlusion光区域的环境遮挡

Cavity — paint only cavity areas. When this option is used, settings of the curvature are available.Cavity：仅对空腔区域进行涂漆。使用此选项时，曲率设置可用。
Convexity — paint only convex areas. When this option is used, settings of the curvature are available.Convexity：仅绘制凸面区域。使用此选项时，曲率设置可用。


Cavity凹面	Convexity凸面

Painting the cavity/convex area can be useful when, for example, you need to paint a cavity/convexity mask for a huge building.例如，当您需要为一个巨大的建筑绘制一个凹面/凸面蒙版时，绘制凹面/凸面区域是很有用的。

Active Channels

绘制纹理时修改的通道。

UV Channel

UV channel that is used when painting the texture.在绘制纹理时使用的UV通道。

UV Channel 0 — 1st UV channel.第一个UV通道。
UV Channel 1 — 2nd UV channel.UV Channel 1：第二个UV通道。

There are no specific requirements for the number of UV channels — you can have either one or both. Just make sure to choose the correct channel when painting: you should know in advance which UV channel the texture will use. For example, if a mask for blending materials uses 2nd UV channel, you will choose UV Channel 1 when editing this mask.对于UV通道的数量没有特定的要求；您可以有一个或两个。只要确保在绘画时选择正确的通道:您应该提前知道纹理将使用哪个UV通道。例如，如果用于混合材质的蒙版使用第二个UV通道，则在编辑此蒙版时将选择UV Channel 1。

注意

使用两个通道绘制纹理会产生不正确的结果。

By default, textures use the 1st UV channel. If necessary, you can change it in the material via the Material Editor.默认情况下，纹理使用第一个UV通道。如果需要，您可以通过材质编辑器在材质中更改它。

If you want to use the 2nd UV channel when painting, but it is empty, you can perform automatic unwrapping for this channel when importing the model into UNIGINE.如果您想在绘画时使用第二个UV通道，但它是空的，您可以在将模型导入UNIGINE时执行自动展开该通道。

Stroke Mode Specific Settings笔画模式特定设置#

The Rectangle and Linear Gradient stroke modes have additional specific settings described below.Rectangle和Linear Gradient笔划模式具有下面描述的其他特定设置。

Depth Limit

填充当前视口中不可见的物体区域的深度限制(即被其他物体遮挡)。

Depth Limit Gradient Length

沿填充区域边缘的渐变大小。

Rectangle Texture

Texture that fills the selected rectangular area. Available for the Rectangle mode only.填充所选矩形区域的纹理。仅对Rectangle模式可用。


Object with Original Texture具有原始纹理的对象	Rectangular Texture Applied应用矩形纹理

Rectangle Texture Opacity

控制矩形纹理应用的1通道不透明度纹理。纹理的白色区域使矩形纹理的相应区域完全可见，黑色区域使其完全透明。
