Studio Max导入物体 If you make your 3D objects in 3dsMax, you can export them into
Unity using the Autodesk .FBX format. 如果你在3dsMax中制作你的3D物体,你可以输
出为格式到Unity中使用.
本帖隐藏的内容需要回复才可以浏览
1. Download the latest fbx exporter from Autodesk website and install it. 从
Autodesk Website下载最新的Fbx输出插件并安装.
2. Export your scene (File->Export or File->Export Selected) in .fbx format on
your PC. Using default export options should be okay. 在Pc上输出你的场景为.fbx
格式(File->Export 或 File->Export Selected),用默认输出选项可能不错.
3. Move the exported fbx file into your Unity project folder on the Mac. 移
动输出的Fbx文件到你Mac上的Unity工程文件夹.
4. When you switch back into Unity, the .fbx file is imported automatically.
当你切换到Unity,这个.Fbx文件将自动导入.
5. Drag the file from the Project window into the Scene view. 从工程窗口拖拽
这个文件到场景视图中.
Unity currently imports from 3ds Max Unity
可以从3dsMax导入的:
1. All nodes with position, rotation and scale. Pivot points and Names are also
imported. 所有节点的位置,旋转和缩放,轴心和名字都可以被导入.
2. Meshes with vertex colors, normals and one or two UV sets. 和网格有关顶点
颜色,法线和一个或二个Uv
3. Materials with diffuse texture and color. Multiple materials per mesh. 固
有纹理和颜色的贴图.多维材质.
4. Animations. 动画
5. Bone based animations. 基于骨骼的动画.
Exporter options
输出选项
Using default FBX exporter options (that basically export everything) should
be okay in all cases. 可以用Fbx预置的选项处理大多数的输出情况.
Default FBX exporter options (for fbx plugin version 2006.11.1) 预置Fbx输出
选项(fbx plugin version 2006.11.1))
Exporting Bone-based Animations
输出基于骨骼的动画.
There is a procedure you should follow when you want to export bone-based
animations: 如果你想导出基于骨骼的动画,可以参考下面的步骤.
1. Set up the bone structure as you please. 倾力架设一个骨骼结构
2. Create the animations you want, using FK and/or IK 创建你想要的动画,用FK
或IK
3. select all bones and/or IK solvers 选择所有的骨骼或者IK
4. Go to Motion->Trajectories and press Collapse. Unity makes a key filter, so
the amount of keys you export is irrelevant 转到Motion->Trajectories并按下
过滤掉不相干的关键帧
5. "Export" or "Export selected" as newest FBX format "Export" 或"Export
selected"一个新的Fbx文件.
6. Drop the FBX file into Assets as usual 和往常一样拖拽Fbx文件到Assets
7. In Unity you must reassign the Texture to the Material in the root bone 在
Unity中你必须在指定贴图材质到基本骨骼.
When exporting a bone hierarchy with mesh and animations from 3ds Max to Unity,
the GameObject hierarchy produced will correspond to the hierarchy you can see in
"Schematic view" in 3ds Max. One difference is Unity will place a GameObject as the
new root, containing the animations, and will place the mesh and material information
in the root bone. 当从3dsMax中输出一个含有骨骼的网格和动画, 游戏物体将产生对应
的层级,你可以在3dsMax的"Schematic view"看到.不同的是,Unity中将设立一个物体做为
新的含有网格和材质贴图的基础骨头. If you prefer to have animation and mesh
information in the same Unity GameObject, go to the Hierarchy view in 3ds Max, and
parent the mesh node to a bone in the bone hierarchy. 如果你希望Unity中在同一个
游戏物体上拥有动画和网格信息,到3ds Max的层级视图,和在骨骼层级到父网格节点.
Exporting Two UV Sets for Lightmapping
为光影贴图输出两个Uv贴图
3ds Max' Render To Texture and automatic unwrapping functionality can be used
to create lightmaps. Usually one UV set is used for main texture and/or bumpmaps,
and another UV set is used for the lightmap texture. For both UV sets to come through
properly, the material in 3ds Max has to be Standard and both Diffuse (for main
texture) and Self-Illumination (for lightmap) map slots have to be set up: 3dsMax
的渲染到纹理和自动展开功能可以用来建立光影图.通常一层UV是用于主要纹理或凹凸贴
图,而另外一层UV是用来光影图.材质在3ds Max中通过标准的固有色(主纹理)和自发光(光
影图)来设定:
Material setup for Lightmapping in 3ds Max, using self-illumination map 在
3dsMax中调整光影图材质,使用self-illumination map. Note that if object uses a Shell
material type, then current Autodesk's FBX exporter will not export UVs correctly.
提示:如果物体用一个外壳材质类型,那么现在的Autodesk’s Fbx输出器还不能正确的输出
Uvs. Alternatively, you can use Multi/Sub Object material type and setup two
sub-materials, using the main texture and the lightmap in their diffuse map slots,
like shown below. However, if faces in your model use different sub-material IDs,
this will result in multiple materials being imported, which is not optimal for
performance. 另外,你可以用多为材质类型和设定两个子材质,使用主纹理和其光影图在他
们的固有贴图槽.如下所示.但是,如果在你的模型上使用不同的子材质ID,这将导致多个材
质导入,这将不是最佳的性能.

material 在3dsMax中调整光影图,用多维子材质.
Troubleshooting
故障处理
If you have any issues with importing some models: ensure that you have the latest
FBX plugin installed. It can be downloaded Autodesk website. 如果你对导入物体有
任何问题,请确保你的Fbx插件是最新的.你可以从AutodeskWebsite更新.
