oh yaeh, I also forgot to mention to you when exporting to obj format. I would not suggest texturing you objects in any kind of 3d app if your only going to export as an obj file afterwards. The reason being is because you will do all that hard earned work laying out the uv's and mapping your textures into your object to find out that none of this will be included in the export. Obj format is the most standard format their is when it comes to 3d modeling. It is like you creating a Microsoft word document with all the fancy fonts and then saving it as a txt file which will result in lost of the different fancy fonts and font sizes that you used to create your document.
