This is the thing.
I'm pretty new with autodesk maya, I googled this question and I did everything they told me to do (Plug-in manager, select obj and export the obj file) but when i loaded the obj. file it doesn't apear anything, it's like nothing happened.
I don't know what I did wrong... I tried more than once and its always the same...
Help me please (Sorry for my english)
PD: I'm using Autodesk maya 2013
To confirm that the .obj file was exported properly you should try to import it back into Maya, into a new scene to see if it comes in.
If it does come in, then its possible that the issue is on the other applications side that you are importing into.
Another thing to check is the Placement and Scale of the object. Sometimes importing a mesh into another software will set the mesh out in space (not centered on the grid) or the scale may be really large or small.
Best Regards.
