纹理编辑器
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:
You can also use the Shift+2 hotkey to activate the tool.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:
