Sometimes we need to make objects in our renderings dirty. Why? Because nothing in real life is polished clean to perfection. There are always imperfections, no matter how miniscule: scruff marks, swirls, fingerprints, scratches etc. With that in mind, today I'm going to talk about how to use various tools within Vray and 3ds to simulate dirty, smudgy wine glasses, as well as how to create wine legs dripping down the interior of the glass. This will be part of a series of tutorials I will be doing analyzing how we can continue to add imperfections to our renderings in order to elevate their photorealism and just make them overall more interesting.
I've also made a video version of this tutorial, split into two parts. You'll find a link to each at the bottom of the page.
Also, I've made the files available to download so that you can follow along. Make sure you're using the latest Max and Vray:
