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


While “UV Reference” layer is selected change it’s style from “Normal” to “Multiply”, so you can see the layers underneath. Make a new layer under the “UV Reference” and call it “Bump”.



Now, we need to gather some images to draw “CocaCola Logo”, and “small dots” on our bottle. To make the small dots under Logo I used the following texture.


The rest of small dots can be simply made by using “Ellipse Tool” in Photoshop and duplicating them using “Alt+Drag”.


Here is the “Coca-Cola Logo” I found on Google which is a nice high resolution image with transparency. Simply, convert the color to white with black background.


Now that we have all the images we need, you can start aligning them on our UV we exported from Maya. Here is what I came up with.



Save the final image as tga format and name it “CocaCola_Bump.tga”.


Step 11: Setup bump map in Maya: Simply make a blinn shader and apply our texture (“CocaCola_Bump.tga”) to its Bump mapping section. Try to reduce the “Bump depth” to something around 0.040. Also, make sure reflection is set to zero.



Apply the Blinn shader to our CocaCola bottle. Make sure “Smooth shade all”, “Textured”, “High quality” is check on, so we can see how our bump map looks like in the viewport. You should get something similar to this:
