Tips: v-ray for nuke
Advanced compositing techniques
In last month’s article I went over how to create and use the Position pass in order to generate custom mattes, to speed up our V-ray for Nuke workflow. This issue I’m going to go over some more advanced V-ray for Nuke techniques and ways to use them.
The majority of the V-ray for Nuke nodes may feel familiar, allowing us to figure them out using logic and experience of standard Nuke nodes. Understanding these should complete your introduction to the plug-in and put you in a good place to efficiently use V-ray for Nuke on any project. Here I’ll give you an intro to a selection of these nodes as well as some tips, so you feel comfortable using them. You don’t have to use V-ray for Nuke primarily for rendering. I’ve personally used the plug-in to enhance initial renders that I’ve been given. For instance, you can create your own fake fog, to give you volumetrics in the places you need it. I’ve even added rim lights which I’ve then added over the render that I’ve been given. Being able to adapt the plug-in to the way I work has made it incredibly powerful. As you use the plug-in more you’ll want to understand how you can optimise your render times. The V-ray Sample Rate AOV that we can get V-ray for Nuke to kick out for us is incredibly useful when refining your render settings to get the render time down.
The AOV gives you a colour guide as to where you subdivisions are being used, so that you can decide if they are being used in the correct places and make decisions accordingly.
Ideally you don’t want your AA (Antialiasing) being calculated on glossiness and shadows. In this article I’ll also show you how to set this up. For all the assets you need go to creativebloq.com/vault/3dw208
