I'd need to see the obj files you were trying to import. More than likely blender is using culture specifics and thus is writing decimal points using the european way ',' instead of the american way '.'. This is no problem as I added a menu option in the menu that tells the app to use culture specifics for situations like this. See here:

I'd still like to see the obj files produced by blender.
As far as exporting to tga that's the way I have the app setup currently. I was thinking about letting the user decide what format they want the images to export to via an interface. What do you think? Basically you would be able to export images in any of the formats under the misc tab.
Finished coding the extended data for when you add a new bone. Works perfectly for normal GR2 files but the special GR2 files don't work correctly yet. Should have it all fixed and completed here soon
