Hi Burr, check these out:

I think the original discussion was here:

http://moi3d.com/forum/index.php?webtag=MOI&msg=987.8

That was one where you would control it by generating a .js text file with a line in it for each file you wanted to convert. Then you pass that .js file as a command-line argument to moi.exe (use " " if it has spaces in it) so it will load that script and execute it when launched.

And then later on there was another discussion here:
http://moi3d.com/forum/index.php?webtag=MOI&msg=2100.1

That second one had a script that would handle looping through a directory and converting all the files of a particular type it could find in there. Something like that anyway.

Let me know if what you need is not covered in either of those threads.
