资源类型
There are a number of file types supported by the UNIGINE assets system. This page contains a categorized list of these file types along with a brief description.UNIGINE支持多种文件类型资源系统。此页面包含这些文件类型的分类列表以及简要说明。
Geometry and Animation几何与动画#
Mesh is the basic unit, that consists of a set of polygons and is used to create geometry for worlds in a UNIGINE project.网格是基本单位，由一组多边形组成，用于为UNIGINE项目中的世界创建几何。
Some meshes can be animated, apart from a set of polygons representing its surfaces, such mesh has a hierarchical set of interconnected bones (a skeleton or a rig) which can be used to animate the vertices of the polygons. Another way to animate a model is to create morph targets (or blend shapes), these are "deformed" versions of a mesh, stored as a series of vertex positions. In each key frame of an animation, the vertices are interpolated between these stored positions.除了代表其表面的一组多边形外，某些网格还可以进行动画处理，这种网格具有一组层次化的互连骨骼（骨骼或装备），可用于为多边形的顶点设置动画。制作模型动画的另一种方法是创建变形目标（或混合形状），它们是网格的“变形”版本，存储为一系列顶点位置。在动画的每个关键帧中，在这些存储的位置之间插入顶点。
Exported 3D model导出的3D模型You can create 3D models, rigs, and animations in an external modeling application (3DSMax, Maya, Softimage, etc.), and then import them to your UNIGINE project via the Asset Browser.您可以在外部建模应用程序（3DSMax，Maya，Softimage等）中创建3D模型，装备和动画，然后通过资源浏览器。
It is recommended to use FBX as an intermediate file format to bring your 3D models to UNIGINE. This format is supported by the most popular 3D editors: Autodesk Maya, Autodesk 3ds Max, Blender, Modo, etc.建议使用FBX作为中间文件格式，以将3D模型带入UNIGINE。最受欢迎的3D编辑器支持这种格式：Autodesk Maya，Autodesk 3ds Max，Blender，Modo等。| Format | Description |
|---|---|
| .fbx |
|
| .dae |
|
| .3ds |
|
| .obj |
注意
If you want to import your 3d model with all materials assigned, you should import all corresponding material library assets (*.mtl files) either prior to importing the *.obj file or together with it.如果要导入已分配了所有材质的3d模型，则应在导入*.obj文件之前或与其一起导入所有相应的材质库资源（*.mtl文件）。 |

Textures贴图#
Textures are images that are commonly used in materials. When a material is applied to a surface, textures are mapped to it. They can be either applied directly, as albedo textures, for instance, used as masks, or the values of the texture's pixels can be used for other calculations. Textures can also be used directly, e.g., as environment cubemaps, or to draw a projection of a Projected Light Source.纹理是通常用于材质。将材质应用于表面时，纹理将映射到该表面。它们既可以直接应用，例如作为反照率纹理用作遮罩，也可以将纹理像素的值用于其他计算。纹理也可以直接使用，例如，作为环境立方体贴图，或绘制对象的投影。投射光源。
A texture mapped to a 3D mesh映射到3D网格的纹理Textures are generally created using an external image-editing application, such as GIMP or Photoshop, and then imported via the Asset Browser. Some textures, such as render textures, are generated by the UNIGINE Engine. They generally take some information from the scene and render it to a texture to be used elsewhere.通常使用外部图像编辑应用程序（例如GIMP或Photoshop）创建纹理，然后通过Asset Browser导入。一些纹理（例如渲染纹理）由UNIGINE Engine生成。他们通常从场景中获取一些信息，并将其渲染为纹理以在其他地方使用。
Several textures can be used in a single material for different purposes. For instance, a material may have an albedo texture, an ambient occlusion texture, a normal map, etc. In addition, there may be a map for the Emission and Roughness stored in the alpha channels of one or more of these textures. 可以在一种材质中使用多种纹理以达到不同的目的。例如，一种材质可能具有反照率纹理，周围遮挡纹理，法线贴图等。此外，可能存在一个或多个这些纹理的alpha通道中存储的Emission和Roughness的贴图。
