I've recently come back to Blender after not using it for a while and I'm trying to reacquaint myself with everything.
I've been working on a model of a product to be used on a company's website. It's fairly simple, they supply boxes of different drinks to bars, restaurants etc. So the model is just a box which will have different labels on for each flavour.
There are around 50 variations and the render time takes around 25 - 30 minutes each.
Because the only thing that is changing is the textures for the labels I was wondering if there is anyway to either keep the parts of the scene that don't change pre-rendered, or to only render the areas around the labels and then layer those on top of a blank render of the box (in Blender itself or with Photoshop)?
I'm using Cycles if that makes a difference.
