I haven't had as much time as I would like to work with MovieSandbox but I will get to it eventually.  I need a job first.
I am curious on how exactly to work with these .spriteMesh files that the import is asking for.  I'm having trouble finding good current info online about OBJ files and its options.  
I have a few programs I use to create small objects.  I would like to be able to work this into my workflow.
For example: If I want to create a scene that happen in a room, I would like to be able to create the walls, roof, and floor in another app. I have a tiny chrome app that I like to use to make simple .obj files.  
Is there an easy way to convert these files to a structure that moviesandbox can easily read for import.
Also, on the import screen there are a bunch of non-English characters in the file type drop down.  I don't know if they should be there.
