2.4版本的Blender API和2.5以上版本的API有很大的不同，这里只是提供了思路和2.4版本的导出方案。

先提供一个脚本，这个是由Blender调用的，用于转换Ogre的Mesh文件的脚本

import Blender
import bpy
import sys
import os,glob
sys.path.append(r"D:\Program Files\blender-2.49b-windows\.blender\scripts\torchlight");
sys.path.append(r"D:\Program Files\blender-2.49b-windows\.blender\scripts");

import importTL,export_fbx

def ImportMesh(file):
    print file;
    scn = bpy.data.scenes.active
    #Scene.Unlink(scn);
    importTL.ImportOgre(file);

    output = file.replace(".mesh", ".fbx");
    output = output.replace(".MESH", ".fbx");

    export_fbx.fbx_default_setting();
    export_fbx.fbx_write(output);
    return True;


ImportMesh(sys.argv[5].replace("--", ""))

import glob,sys,os

DUMMY_BLEND = r"E:\MyProj\unity3d\arpg36\ARPG\Tool\auto_convert_mesh\dummy.blend"
CONVERT_SCRIPT = r"E:\MyProj\unity3d\arpg36\ARPG\Tool\auto_convert_mesh\convert_mesh.py"

def convert_path(path):
    for root, dirs, files in os.walk(path):
        for dir in dirs:
            strDir = os.path.join(root, dir);
            #print(strDir);

        for file in files:
            file = file.lower();
            strFile = os.path.join(root, file);
            #print(strFile);
            if strFile.find(".mesh") != -1:
                os.system("Blender -b {0} -P {1} --{2}".format(DUMMY_BLEND, CONVERT_SCRIPT, strFile));

    for root, dirs, files in os.walk(path):
        for file in files:
            file = file.lower();
            if file.find(".mesh") != -1 or file.find(".skeleton") != -1 or file.find(".xml") != -1 or file.find(".material") != -1 or file.find(".animation") != -1 or file.find(".adm") != -1:
                strFile = os.path.join(root, file);
                os.remove(strFile);

convert_path(r"E:\MyProj\unity3d\arpg36\ARPG\Assets\Model\Media\Level");

最核心的内容就一样代码 "Blender -b 项目文件 -P 脚本文件 --参数"
