1. Download the latest fbx exporter from Autodesk website and install it. \u4eceAutodesk Website\u4e0b\u8f7d\u6700\u65b0\u7684Fbx\u8f93\u51fa\u63d2\u4ef6\u5e76\u5b89\u88c5.
2. Export your scene (File->Export <\/strong>or File->Export Selected<\/strong>) in .fbx <\/strong>format on your PC. Using default export options should be okay. \u5728Pc\u4e0a\u8f93\u51fa\u4f60\u7684\u573a\u666f\u4e3a.fbx\u683c\u5f0f(File->Export <\/strong>\u6216 File->Export Selected<\/strong>),\u7528\u9ed8\u8ba4\u8f93\u51fa\u9009\u9879\u53ef\u80fd\u4e0d\u9519.

Using default FBX exporter options (that basically export everything) should be okay in all cases. \u53ef\u4ee5\u7528Fbx\u9884\u7f6e\u7684\u9009\u9879\u5904\u7406\u5927\u591a\u6570\u7684\u8f93\u51fa\u60c5\u51b5. <\/p>\n

Exporting Bone-based Animations<\/strong><\/p>\n

\u8f93\u51fa\u57fa\u4e8e\u9aa8\u9abc\u7684\u52a8\u753b. <\/strong>
There is a procedure you should follow when you want to export bone-based animations: \u5982\u679c\u4f60\u60f3\u5bfc\u51fa\u57fa\u4e8e\u9aa8\u9abc\u7684\u52a8\u753b,\u53ef\u4ee5\u53c2\u8003\u4e0b\u9762\u7684\u6b65\u9aa4.
1. Set up the bone structure as you please. \u503e\u529b\u67b6\u8bbe\u4e00\u4e2a\u9aa8\u9abc\u7ed3\u6784
2. Create the animations you want, using FK and\/or IK \u521b\u5efa\u4f60\u60f3\u8981\u7684\u52a8\u753b,\u7528FK\u6216IK
3. Select all bones and\/or IK solvers \u9009\u62e9\u6240\u6709\u7684\u9aa8\u9abc\u6216\u8005IK
4. Go to Motion->Trajectories <\/strong>and press Collapse<\/strong>. Unity makes a key filter, so the amount of keys you export is irrelevant \u8f6c\u5230Motion->Trajectories\u5e76\u6309\u4e0bCollapse.Unity\u8fc7\u6ee4\u6389\u4e0d\u76f8\u5e72\u7684\u5173\u952e\u5e27
5. “Export” or “Export selected” as newest FBX format “Export” \u6216”Export selected”\u4e00\u4e2a\u65b0\u7684Fbx\u6587\u4ef6.
6. Drop the FBX file into Assets <\/strong>as usual \u548c\u5f80\u5e38\u4e00\u6837\u62d6\u62fdFbx\u6587\u4ef6\u5230Assets
7. In Unity you must reassign the Texture to the Material in the root bone \u5728Unity\u4e2d\u4f60\u5fc5\u987b\u5728\u6307\u5b9a\u8d34\u56fe\u6750\u8d28\u5230\u57fa\u672c\u9aa8\u9abc. <\/p>\n

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. \u5f53\u4ece3dsMax\u4e2d\u8f93\u51fa\u4e00\u4e2a\u542b\u6709\u9aa8\u9abc\u7684\u7f51\u683c\u548c\u52a8\u753b, \u6e38\u620f\u7269\u4f53\u5c06\u4ea7\u751f\u5bf9\u5e94\u7684\u5c42\u7ea7,\u4f60\u53ef\u4ee5\u57283dsMax\u7684”Schematic view”\u770b\u5230.\u4e0d\u540c\u7684\u662f,Unity\u4e2d\u5c06\u8bbe\u7acb\u4e00\u4e2a\u7269\u4f53\u505a\u4e3a\u65b0\u7684\u542b\u6709\u7f51\u683c\u548c\u6750\u8d28\u8d34\u56fe\u7684\u57fa\u7840\u9aa8\u5934. 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. \u5982\u679c\u4f60\u5e0c\u671bUnity\u4e2d\u5728\u540c\u4e00\u4e2a\u6e38\u620f\u7269\u4f53\u4e0a\u62e5\u6709\u52a8\u753b\u548c\u7f51\u683c\u4fe1\u606f,\u52303ds Max\u7684\u5c42\u7ea7\u89c6\u56fe,\u548c\u5728\u9aa8\u9abc\u5c42\u7ea7\u5230\u7236\u7f51\u683c\u8282\u70b9.

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\u7684\u6e32\u67d3\u5230\u7eb9\u7406\u548c\u81ea\u52a8\u5c55\u5f00\u529f\u80fd\u53ef\u4ee5\u7528\u6765\u5efa\u7acb\u5149\u5f71\u56fe.\u901a\u5e38\u4e00\u5c42UV\u662f\u7528\u4e8e\u4e3b\u8981\u7eb9\u7406\u6216\u51f9\u51f8\u8d34\u56fe,\u800c\u53e6\u5916\u4e00\u5c42UV\u662f\u7528\u6765\u5149\u5f71\u56fe.\u6750\u8d28\u57283ds Max\u4e2d\u901a\u8fc7\u6807\u51c6\u7684\u56fa\u6709\u8272(\u4e3b\u7eb9\u7406)\u548c\u81ea\u53d1\u5149(\u5149\u5f71\u56fe)\u6765\u8bbe\u5b9a: <\/p>\n
