What programs export .mesh?
I need to export some USGS (US Geological Survey) DEM (digital elevation) model data to .mesh format. I need it to be in Roblox.mesh format . The only program I know of is Anim8tor . It basically does the .mesh like this:

This grid looks something like this
The problem is I have about 200MB of .3ds data that I need to convert to Roblox.mesh, but it fails to export Anim8or.mesh.
Is there any program that will export .mesh?
PS: I know that Roblox turned off the .mesh loading, but I have a script that converts it to the normal Roblox environment

Open the model in Blender and export it to Roblox. grid
== Edit ==
Sorry, I just pointed out some things that I thought would work, but when I tried this I noticed that the add-on was buggy (not much work), so I edited it a bit (this is the first blender addition that i did and i'm not too sure about the .mesh part, but it might work, however expect errors):

I tried it on a monkey head and it seems to work. It should also be noted that I removed the UV mapping and changed a lot of things (not sure if it is being handled correctly in memory, etc.).
Don't forget to activate it. The export to .mesh option should appear in the export section of the file menu.
Another way you can use is to import it into Blender, export it as .obj and import it into roblox .
