do you mean render it out? or actually export the objects ect to use in another package?

exporting your models, you need to have them as polygon meshes and use the export as .obj under the export all tab in the file menu.
file>export all>option box

if you are render your scene you need to go to the render tab and batch render.
window>rendering editors>render settings, change all your settings. then batch render

um yea hope that points you in the right direction
sorry its not in depth as im bnot sure if this is what you mean
