Setup for a wine bottle with multiple labels I have modeled a wine bottle and created various wine label designs for a client. The labels were created in Illustrator and so I have PNGs. I want to present a render of the same bottle with each label the client. The labels are not simple rectangles. 

Should I: 


"model" each label and wrap it on the bottle, or 
try to map each label image to a portion of the bottle's surface? 


I've seen lots of tutorials showing option #2, but something is telling me that the glass of the bottle should be separate from the "paper" label.

Also, with #1, couldn't I use the same bottle blend file and use a different layer for the each label, then turn on a different layer for each new render?

Maybe there's an even better strategy?

thanks,
Create an object that surrounds the bottle, but it's but that is just a bit bigger than the bottle (to avoid Z fighting errors). Unwrap it to get something like this:



Assign a texture using the alpha channel of the texture to control a transparent shader. A mapping node will also help you with the positioning of the label.



Now by changing the image on the Image texture node (and sometimes the scale and placement) you can preview your different labels.
