 该网格看起来像这个 
 
 
 问题是我有大约200MB的.3ds数据，我需要转换为Roblox的.mesh，但Anim8or的.mesh导出程序崩溃。 
 
 
 有没有任何程序可以输出.mesh吗？
 
 
  PS：我知道Roblox已禁用.mesh上传但我有一个脚本将其转换为常规的Roblox地形
解决方案
在 Blender 和将其导出到Roblox的.mesh

 对不起，我刚才指出在某些我认为会工作的东西，但是当我尝试它时，我注意到附件是有缺陷的（没有太多的工作），所以我编辑了一点（这是我做的第一个搅拌机附件，我不太了解.mesh部分，但它可能会工作，但是期待错误）：

我在猴头上尝试过，似乎工作。 
还要注意的是，我删除了UV映射并更改了很多东西（不知道如果它在内存中正确处理等等）。
 
 
 记住激活它
导出到.mesh的选项应该出现在文件菜单的导出部分。
 
 
 
 
 
 另一种方法您可以使用的是将其导入Blender，将其导出为.obj，并将导入它在roblox 。
 
I need to export some USGS (U.S. Geological Survey) DEM (Digital Elevation Model) data into .mesh format. I need it to be in the Roblox's .mesh format though. The only program that I know that does this is Anim8tor's program. Basically it makes the .mesh look like this:

That mesh looks something like this

The problem is that I have about 200MB of .3ds data that I need to convert to Roblox's .mesh but Anim8or's .mesh exporter crashes. 

Is there any program that exports .mesh like that?

PS: I know Roblox disabled .mesh uploading but I have a script that converts it into regular Roblox terrain

Open the model in Blender and export it to Roblox's .mesh

==Edit==

Sorry, I just pointed at some stuff that i thought would work, but when I tried it I noticed that the add-on was flawed (not much of it was working) so I edited it a bit (it is the first blender add-on I have made, and I am not too sure about the .mesh part, but it might work, however expect bugs):

if __name__ == "__main__":
    register()
I tried it on the monkey head, and it seems to work.
Also to note is that i removed the UV mapping and changed lots of stuff (no idea if it is handled correctly in memory and so).

Remember to activate it.
The option to export to .mesh should appear in the export section of the file menu.



Another method you could use is to import it in Blender, export it as .obj, and import it in roblox.
