Ed:

Great render.

<< I made a custom material using a flat photo of a real bottle cap as a label (decal) applied to the model, rendered in KeyShot.>>

What software did you use to apply the label?

YHWH_777 - The label is made from a straight on photo of an actual Pepsi bottle cap, copied using a round selection tool, and saved as a transparent png. The png photo is applied as a label (decal) within KeyShot's material editor. KeyShot has the ability to load images, resize and position them over the model. Great for applying graphics to cars or labels to wine bottles :) The reflections in the Pepsi bottle cap are coming from the HDRI environment I selected in KeyShot.
