3d model texture conversion

Is there any way to convert textures from a 3d model from 3ds max to the same model except in .obj format?

I find when converting my models into .obj format and import them into zbrush, the texture maps no longer apply as they should because the model becomes all one object. Is there a quickie solution to this? I dont want to have to retexture all my models

I suppose that you remember that ZBrush needs vertically flipped textures You may export each element as separate obj file and import them to ZBrush as subtools. You'll have each needed element separate in ZBrush then.
