The short answer for your case is that the texture mapping on the model has been normalised. I'm guessing that you edited it in Cinema 4D and exported as a Wavefront (OBJ) file to import back into BinEdit. The OBJ doesn't store any texture-mapping information, so BinEdit just applies the texture to each face as a default. If you follow the steps of the mapping tutorial above (it should be easier than as written since BinEdit 2 is greatly improved in this area) you can remap the textures, however you'll be pretty busy remapping the entire truck body. An easier way might be to discard the parts of your model that you haven't change (such as the Bigfoot body) and 'pasting' your new parts onto the original Bigfoot (which has its original texture mapping):
- Delete the faces of the original model (the truck body).
- Press Spacebar to cycle through the faces.
- When you come to a face you want to remove, press Ctrl+Del.
- In the end you should end up with just your spoiler (and perhaps some other bits if there is anything else you added or changed on the original model). Save it as a BIN model.
- Open BIGFOOT.BIN and Repeat steps 1 & 2 to remove the corresponding faces that you left behind with your spoiler model (if any).
- Go to Insert -> Model and open your spoiler.bin. Tadaa! You spoiler should now be inserted onto the Bigfoot model. Now you only have to map your new spoiler, not the whole truck body.
Note 1: You will probably have to rescale your spoiler model to make it fit, as the imported model will be a different size. Easiest way to do this would be before deleting anything, open the Bigfoot.bin and go to Model -> Resize and note the dimensions. Copy a common dimension (like the width or height), go back to your edited model and resize it to that dimension. They should then be a perfect fit when you do the insert step. Alternatively, if you have the forethought to save a vertex group of the spoiler (which I won't go into here), you can resize and move the spoiler after it has been inserted.
Note 2: After deleting faces you will have a lot of unconnected vertices. Go to Vertex -> Delete All Unused to clean them up.
