As you all know, and are struggling with, mesh exporting from blender to obj files can take quite some time and effort, since we are needing to divide up our models into x pieces and then needing to export them one-by-one and naming them while at it. So, until we get multi-import in studio we can use this sweet add-on I assembled (found the syntax somewhere, and plugged it into a .py file). It basically allows you to make an .obj export “batch,” and cycles through each model selected (very important, you have to select all the parts you want exported) and exports it to one file place (that you choose), and the names for the files are named after the actual object names in the 3D space, so thats another sweet feature.
To install this addon in blender, go to User Preferences > Addons > Install from file > select the downloaded file and click the checkmark next to it when it appears, and click save user settings.
Hope that helps, enjoy!
