Hehe, even if 3DS Max is better, I still prefer Blender, as it's more user-friendly.
Here's a step-by-step tutorial on how to apply textures in Blender :
1. In Blender, import the OBJ file.
2. Select to separate as Material, Group and Object (I think it's that, not sure. You have to press the three buttons at the middle.)
3. Left-click on a part to select it. Then you can move it around. Do it for every part.
4. Next, in another window (to the right/bottom of the screen) you change it for "UV/Image Editor"
5. Next, go into "Textued" mode (you have to click on a little dropdown box with some kind of a spehre on it, then select Textured)
6. Go into Edit Mode (click on "Object Mode" and choose Edit Mode)
7. Image > Open Image then select the texture. If it's not the right one you open another. Don't replace, or else every other part that use this texture will also be changed.
8. Once it's done, go back into Object Mode to see! It's done, you have your model textured.
Of course there could be different stuff sometimes. If you need more precise help, you can add me to MSN (
