Modeling of Coca-Cola Bottleby Hamed Sabri Web: www.hamed3d.org


Step 8: UV Mapping - To setup the UVs I used “UV Layout 2”. Select “Coca_Bottle” in the scene and export it as obj. Load the obj file in “Uv Layout 2” and layout the UVs as following. I am not going to cover how to use UV layout in this tutorial but if you are not familiar with it you can easily learn it by following the tutorials that’s on their website. Here is the link:

Once, you are done with UV’s Export the model back to Maya.

UV mapping the Cap’s treads can be easily done in Maya using simple planar map. We apply a planar map to one tread and then we transfer its UV information to rest of 19 treads. This way all UVs pile up exactly on top of each other.


Transfer UV maps:

To transfer one object’s UV map to another object, first select the object that has proper UV layout and then the second object with no proper UV layout, then go to Meshà “Transfer Attribute Options” and in this case set the options as following:


Do this step for the rest of 19 treads. Once you are done, all the UV’s are perfectly piled up on top of each other. Merge all the tread to one object. Call the new object “Cap’s Tread”


Step 9: Exporting “Coca_Bottle” UV to Photoshop for bump mapping: Select “Coca_Bottle”, and then go to “UV Texture Editor”. Once UTE pops up, go to “Polygonsà UV snapshots… set its options as following:


Step 10: Setting up UV as a guide in Photoshop: Once UV image is loaded in Photoshop, press “Ctrl+I” to invert the colors. Double click on the lock icon to pop up the new layer window. Call the new layer “UV_reference” and hit ok.
