Object name while OBJ exporting

 From:  falcon76

Hi all,
here is my little problem.
While waiting for the next version with Object Organization, I want to use moi to model with my laptop.I'm trying to find some render engine for texturing the model, without using a main application (I have only a license in the office for that).
Exporting inside a render engine all the model in one time can be hard to assigning material.
So I start exporting object by object in OBJ format. But in this way during import, the render engine ask everytime to replace or rename...
There is a way to rename the object inside the OBJ file (maybe with filename001, filename002...)?
Another little things is that at the end of exporting the choosed object are not selected. So I cannot Hide or delete and I have to select it again.
Someone have some tips for that? Or a totally different workflow?

Thanks
Luca
